College publications are given 2-part "pub numbers" that are used to identify them. The first part (the prefix) is a set of letters that indicates which series the document belongs to. A series is a grouping of documents that share similar content. The second part of the pub number is just a sequential number.
In descending order, by date published.
The objective of this publication is to provide practical tips for installing electrified offsets that can effectively control livestock and extend the life of new and existing fencing.
A University of Kentucky research collaboration analyzed footing samples for metal concentrations as part of a larger study on indoor arenas. By determining what metals are present within the indoor arena footing, we can begin to develop an idea of the metals which could potentially become airborne particulates as horses are worked in the arenas. To date, metals havenít been as widely considered when considering respirable particulate matter (PM) that can impact horses and humans in the arena environment.

Kentucky is ideally suited for cattle production. The main feed for cattle is a renewable resource Kentucky has in abundance--forages. The majority of the state's terrain favors cattle production over row crops. Kentucky farms cover 14 million acres, with approximately half of that occupied by forage grasses and legumes. Our natural resources and climate permit the growth of most cool-season and warm-season species. Water is readily available in all areas of the state, and we have a relatively long growing season.

Blackpatch is an important fungal disease of forage legumes in Kentucky. A metabolite produced by the fungus can result in slaframine toxicosis or "slobbers" in many animals. The fungal disease was first reported in Kentucky in 1933 on red clover. Most Extension literature associates blackpatch and slaframine with red clover, which is very susceptible to the disease. However, many forage legumes including alfalfa can be infected by the causal fungus.
A well-planned and properly kept garden should produce 600 to 700 pounds of produce per 1,000 square feet and may include many different crops. Consult "Vegetable Cultivars for Kentucky Gardens" (ID-133) for the latest recommendations on home vegetable varieties.

Once wheat and other small grains adapt to cooler weather in the fall, they are relatively tolerant of cold temperatures and freeze injury. Frost injury in the spring normally occurs when February and March are unusually warm and small grains initiate growth earlier than normal or from an unusually late frost event. Freezing temperatures during sensitive growth stages can significantly impact grain yield. In some cases, the impact on yield can be moderate to severe.
This guide gives a basic overview of drags, their component parts, and other arena maintenance equipment. Selecting the proper equipment and maintenance protocol is essential for keeping a usable and well-maintained arena. Because there is variation in the terminology used between manufacturers, this compilation of basic terms, descriptions, and pictures will improve the arena manager's understanding of common terms.
Maintenance is a key aspect to extend an arena's lifespan, and it is extremely important for the horses and riders who use the surface. Arena maintenance is essential for the casual recreational rider up to the high-performance athlete. The surface the horse encounters during work has a profound impact on the horse's biomechanics, which can affect the horse's soundness over time. Having a well-maintained surface increases your horse's performance capabilities and enhances training.
This publication provides an overview of riding arena characteristics, and in particular, footing. Many different factors must be considered when planning to build an arena or determining how to care for an existing arena. This basic guide explains how arenas are structured, describes the components that generally make up arena surfaces, and discusses various considerations that all arenas need.
Kentucky is in the upper transition zone which allows for the growth of warm- and cool-season forages. Corn, a warm season grass, grows well in the state and may be harvested for either grain or silage. Corn harvested as silage can be an economical alternative for beef cattle. Implementing sound management strategies and determining the nutrient content to balance rations will allow for successful feeding of corn silage to beef cattle.
Will pasture-finished beef eventually become a commodity with lowered product prices? These and other questions must be evaluated by those considering pasture-based beef finishing. As with any new enterprise, however, the learning curve is steep, and success requires a commitment to working through the many production, marketing, and processing details. This reference guide provides a foundation for this process.
Kentucky has several bourbon distilleries and one fuel ethanol plant. The spent grains from the production of ethanol is utilized as a protein source in livestock feed. Shutdowns for fuel ethanol plants may also occur as a result of unfavorable profit margins when crude oil prices are low. Most distilleries and fuel ethanol plants will have a scheduled maintenance shutdown each year. During a shutdown, availability of distillers grains and other coproducts from these plants may be limited or unavailable. So, the question is what else can I feed in place of distillers grains?
Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky peach plantings.
During summer months, horse owners hang fans around their barn and stalls in an effort to increase air movement to reduce temperature and flies in stall areas. These fans typically are 20-inch 3-speed box fans or 20-inch high velocity mounted fans. Both fans are easy to find at any home improvement or big box store and are ready to use with little to no assembly. But are these commonly used fans really serving these intended purposes?
Many horse owners involved in the industry look for an indoor arena in which to work horses regardless of weather. These facilities might be at home or at a community location for many riders to access. The following highlights some common characteristics and requirements of indoor arenas. While these act as minimums, many disciplines and activities may require additional investment in facilities, such as larger dimensions, more lighting, special footing, etc.
Weaning is the process of separating suckling offspring from their dam. Weaning is a management procedure applied by the herd manager. Cattle are herd animals and their gregarious nature can lead to stress as a result of this separation. Managing the weaning process can aid in reducing stress for the animals and livestock managers.
Tree failures, especially in urban and recreational areas can result in harm to human life and property. While this is rare, it is important to recognize that the environmental and sociological benefits provided by trees significantly outweighs the limited risks presented by trees. This is especially true when defects and species profiles that increase the potential for failure can be observed or detected. Many of these defects are associated with certain species. This is referred to as the species failure profile.
For those with a green thumb, growing plants may seem easy. However, when plant problems arise, determining the cause of these issues can be difficult. Developing the skills necessary to determine the cause of a plant problem takes experience and time. The steps involved in the diagnostic process first require analysis of information regarding the history of the symptomatic plant and the surrounding area. Plant symptoms and signs provide additional evidence to aid in determination of a possible cause.

Pollution in the environment cannot always be avoided. However, eating for good health may help reduce the effects of pollution in the body. Choosing more nutritious foods, such as those high in phytonutrients, may reduce oxidative stress and protect the body from the negative health effects of pollution.
Blackberries are fresh and in season during the mid summer months. But this does not mean you cannot eat them year round. In addition to buying frozen berries during the winter months, you can also plan ahead and freeze your berries when they're in season. Frozen berries are just as healthy and easy to use as fresh.
So you've heard how blackberries are good for your health. Growing blackberry bushes as a garden project can be quite rewarding, especially if you do it as a group. Your local Cooperative Extension Office or non-profit organization may have the perfect place for planting the bushes where berries can be shared with an identified community. With a little sunshine and good drainage, the right variety, and proper blackberry plant care, a group can work towards a successful harvest.
Winter feeding of cattle is a necessary part of nearly all cow-calf operations. In winter months, livestock producers often confine animals to smaller "sacrifice" pastures to reduce the area damaged from winter feeding. A poorly chosen site for winter feeding can have significant negative impacts on soil and water quality. Such areas include locations in floodplains, such as those along creek bottoms or around barns near streams. These locations are convenient, flat areas for setting hay ring feeders; however, their negative effects on water quality outweigh the convenience.

Many urban homeowners are not sure what to do about the stream in their backyard. Who owns it? How can I take care of it? What plants are good for my streambanks? These common questions lead to some confusing answers. This publication is designed to help the homeowner of a backyard stream appreciate this resource, protect personal property, and improve water quality and habitat.
Pituitary pars intermedia dysfunction (PPID) is one of the most common endocrine diseases in horses, generally affecting those over the age of 15 years. It is also frequently referred to as Equine Cushing's Disease. PPID is caused by degenerative changes in an area of the brain known as the pituitary gland, hence the name of the disease. This gland is located at the base of the brain. In horses with PPID, the specific section of the pituitary gland that is most affected is called the pars intermedia. Unfortunately, in horses with PPID, changes occur within this gland, which results in increased production of a hormone called adrenocorticotropic hormone (ACTH).
Scouting and monitoring diseases, insects, weeds, and abiotic disorders in order to identify potential problems before they result in serious losses is essential to the IPM approach. The key to effective monitoring is accurate identification. The pictures included in this guide represent the more common abiotic and biotic problems that occur on vegetable crops grown in high tunnel and greenhouse structures in Kentucky. This manual is not all-inclusive, and growers may encounter problems not included here. Please contact a local Cooperative Extension Service office for assistance.

Cannabis sativa is a summer annual plant that is strongly photoperiod-sensitive (flowers according to day length/photoperiod; not physiological maturity). It is mostly dioecious in that male and female flowers occur on separate plants (i.e. there are both male plants and female plants). However, there are also several monoecious commercial varieties (male and female flower parts on the same plant). Different plant parts are harvested for specific purposes, and modern day hemp may be produced for one or more purposes. Depending on the harvestable component of interest, (i.e. fiber, grain or cannabinoids) male plants and/or pollen might be vitally necessary or completely unwanted.

This publication provides information on soybean growth and development, principles of variety selection, and management practices to maximize soybean profitability in Kentucky.
Although most would agree that gardening is a worthwhile endeavor, traditional gardening with long neat rows spaced 3 or 4 feet apart to allow cultivation by a tractor or tiller may not be feasible for everyone. Individuals that live in urban areas, especially those living in townhomes, condominiums, and apartments may not have the outdoor space needed for this conventional style of gardening. In addition, those with limited mobility may not be able to establish and maintain this type of garden. For many, raised bed gardening and container gardening may be a more practical and manageable choice for those gardening in small spaces and those with limited mobility.
Potential producers should realize that while thornless semi-erect varieties produce superior economic returns, thorny and thornless erect varieties may hold some marketing advantages that can command superior prices and result in better returns than those estimated using these standard assumptions.
There has been an increased interest in pasture-raising poultry for both meat and egg production in the last decade. Raising poultry on pasture was a common occurrence until the latter half of the 20th century. Fresh forage provided an important ration balancing factor during the years before poultry nutritionists fully understood the required essential vitamins and minerals for growth and optimum meat and egg production. With the development of balanced rations, poultry no longer require access to pasture and year-round production of meat and eggs is possible. However, there are still some benefits from the lush forage, invertebrates, and exercise that pasture provides. In addition, we continue to learn more and more about the positive influence that fresh grasses and legumes have on fatty acid profiles and general bird health. As a result, there is an increased interest in pasture-raised poultry for both meat and eggs.
The most common reason trees and shrubs fail to perform as anticipated is that their cultural requirements differ from the site characteristics. People often plant things they know and love from a distant state, purchase because they are on sale, or find attractive but don't understand the environmental requirements. In some cases, a site can be easily modified to make it more suitable for a desired species. Most of the time, it is difficult or impossible to change the site characteristics enough for the plant to thrive. Appropriate watering is essential for establishment of recently transplanted trees and shrubs. This becomes even more important (and challenging) for plants poorly matched to their sites. Selecting plant species that will thrive under particular site conditions is an easier and less expensive option. The first step in doing this is to understand the site where you plan to plant.
The scientific scale for measuring how acidic or basic a substance is when it is dissolved in water is called pH. The pH scale runs from 0 - 14. 0 means it is very acidic, 7 means it is neither acidic nor basic, but just right in the middle like plain water (neutral), and 14 means it is very basic. If you are producing a food product that depends on the acidic components or ingredients of the product to extend its shelf life and ensure the safety of the product, monitoring the pH of food products is very important. Food safety is the biggest reason for monitoring pH, but pH also influences the quality of food products.

La sociedad moderna demanda alimentos variados y de buena calidad, esto implica un reto para los agricultores de frutas, hortalizas y granos, ya que deben producir lo suficiente para obtener ganancias y al mismo tiempo, evitar la contaminacion del producto requerido por la poblacion. El Manejo Integrado de Plagas, es una herramienta importante en el manejo de los cultivos, ya que propone alternativas de control que no se limitan unicamente al uso de pesticidas, sino tambien, a tomar ventaja de los recursos existentes en el campo, tales como, organismos beneficos, plantas florales, biologia de la plaga, rotacion de cultivos, labores culturales apropiadas y otros mas que permiten manejar con perspectiva ambiental los problemas encontrados.
As urban expansion spreads, there is a loss of natural habitat for wildlife. Wildlife has come into closer contact with livestock operations, and some of these animals are predators of poultry.
Good Agricultural Practices (GAPs) are necessary to ensure that fresh fruits and vegetables are harvested, handled, and packaged in a sanitary manner. Field crops are at a higher food safety risk than processed foods because of regular exposure to several sources of contamination, including soil, manure, human handling, domestic and wild animals, and water. While it is impossible to completely eliminate these risks, GAPs ensure that these risks are as small as possible when implemented correctly.
Unfortunately the emerald ash borer is only the latest in a series of invasive pests that have recently decimated our trees. Here, we provide basic information on the death of our ash trees and what types of species are less likely to be impacted by invasive insects and diseases in the future.
Occasionally, through no fault of your own, your valuable trees and landscape plants may be damaged. Landscape appraisers are called on to assess individual plants and entire landscapes as a result of storms, human damage, destruction, and failure. Appraisals are an estimate of the nature, quality, value, or utility of an interest or an aspect of real estate.
A rotational grazing program can generally be defined as use of several pastures, one of which is grazed while the others are rested before being regrazed. Continuous grazing is the use of one pasture for the entire grazing season.
Integrated Pest Management (IPM) uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The pictures included in this guide represent the more common abiotic and biotic problems that occur in Kentucky strawberry plantings.
Equine Metabolic Syndrome (EMS) is an endocrine disorder that affects equids (horses, ponies, and donkeys) in three defining ways: they are obese and/or have localized fat deposits, they are in an insulin resistance (IR) state, now referred to as insulin dysregulation (ID), and they are predisposed to developing laminitis.
Eighty to 90 percent of disease and insect problems on landscape plants can be traced back to soil problems. Plants must be adapted to the site if they are to meet our expectations of growing, remain healthy, and attractive.
Water is the most essential nutrient for cattle production. Water is used in almost every bodily function, including digestion, milk production, and excretion. Given the role and function of water in relation to animal production, health, and welfare, it is critical that abundant, clean water is available in any livestock production operation. Livestock must have immediate access to water within every paddock of a rotational grazing system to realize maximum efficiency and production.
Nutrients are constantly cycling through farms. Nutrients come onto a farm in the form of feed, commercial fertilizers, manure, or compost, and they leave the farm with harvested crops, sold livestock, and off-site disposal of manure and other waste. Sometimes nutrients are even lost to the air, soil, or water. Nutrient management allows farmers to use nutrients wisely for optimal economic benefit with minimal impact on the environment.

The soft red winter wheat grown in Kentucky is the fourth most valuable cash crop in the state. Winter wheat has been an integral part of crop rotation for Kentucky farmers. Wheat is normally harvested in June in Kentucky and provides an important source of cash flow during the summer months.
Grain sorghum can be used for a variety of purposes including animal feed, unleavened breads, cakes, wallboard, starch, dextrose, brooms, ethanol, high quality wax, and alcoholic beverages. Grain sorghum produced in Kentucky is most commonly used for animal feed and was first grown here in the 1920s. Although acreage in Kentucky has fluctuated considerably over the years, yields have generally exceeded the national average since the 1970s, indicating that grain sorghum is an option for producers interested in diversifying grain crop operations.
Soil acidity is one of the most important soil factors affecting crop growth and ultimately, yield and profitability. It is determined by measuring the soil pH, which is a measure of the amount of hydrogen ions in the soil solution. As soil acidity increases, the soil pH decreases. Soils tend to be naturally acidic in areas where rainfall is sufficient to cause substantial leaching of basic ions (such as calcium and magnesium), which are replaced by hydrogen ions. Most soils in Kentucky are naturally acidic because of our abundant rainfall.

Tomato is, by far, the most common vegetable crop grown in greenhouses in Indiana and Kentucky. This publication examines common tomato diseases of the greenhouse and provides management recommendations.
Strategically locating the watering facility will also provide production benefits such as increased forage utilization and improved access to water, and may possibly reduce the cost per pasture of providing water. This publication will provide guidelines for the location, design, and construction of all-weather surfaces for cattle watering facilities.
In the Southeastern United States, acute interstitial pneumonia has been produced by ingestion of the leaves and seeds of perilla mint (Perilla frutescens). Perilla ketone is the toxin absorbed from the rumen into the bloodstream and carried to the lungs where it damages the lung tissue in cattle.
Esta guia cubre los problemas abioticos y bioticos mas comunes que ocurren en cucurbitaceas (Familia Curcubitaceae) en Kentucky. Este grupo de plantas, al que tambien se refiere como enredaderas trepadoras, incluye al pepino, melon (cantalope), sandia, melones especiales, calabazas (o zapallos), calabacines, y cogordas (conocidas tambien como calabazas de peregrino, ayotes, jicaras, o porongos [gourds en ingles]).
Streams are an important part of the landscape. Streams transport water, sediment and energy; provide habitat for aquatic life and support terrestrial life; provide a place for recreation; and in many cases serve as a water supply. The health of streams---or their ability to perform these important functions---is dependent on the conditions of the watersheds which they drain. Changes in land use within a watershed can affect a stream's health.
Beef Quality Assurance (BQA) is a program developed to ensure that beef and dairy cattle are managed in a manner that will result in safe and wholesome beef and milk products for the consumer. Specifically, BQA is designed to enhance carcass quality by preventing drug residues, injection-site blemishes, and bruises. The Kentucky Beef Quality Assurance Program is based on recommended national guidelines and scientific research. This program enables beef and dairy producers to enhance their product, maximize marketability, and strengthen consumer confidence.

The number of organic dairy cows in Kentucky has been steadily increasing for years, yet there's not enough organic corn produced in the state to feed the growing herds. In short, a new market has developed in the state, but few local farmers are taking advantage of it. While Kentucky farmers are no strangers to corn, growing corn organically utilizes different management, cultural and marketing practices and requires new skills. And, importantly, organic production must follow an approved farm plan that allows farmers to sell their corn as certified organic. This publication is designed to be both an introduction to a new enterprise as well as a practical manual for those interested in pursuing organic corn production on their own farms.
Magnesium is a vital component of normal nerve conduction, muscle function, and bone mineral formation. Hypomagnesemic tetany or "grass tetany" is a disorder caused by an abnormally low blood concentration of the essential mineral magnesium (Mg). Synonyms for this disorder include spring tetany, grass staggers, wheat pasture poisoning, or lactation tetany.
Although infrequent, brassica crops can cause animal health disorders if grazing is managed improperly. Most brassica-related disorders in cattle tend to occur during the first two weeks of grazing while adjusting to the forage. The primary potential disorders are polioencephalomalcia or PEM, hemolytic anemia (mainly with kale), nitrate poisoning, and pulmonary emphysema. Other possible clinical disorders include bloat and rumen acidosis, and metabolic problems such as hypomagnesemia and hypothyroidism with goiter. Glucosinates present in brassicas are precursors of irritants that can cause colic and diarrhea. Large bulbs may lodge in the esophagus and lead to choking. Certain brassicas (specifically rape) can cause sunburn or "scald" on light-skinned animals, especially when grazed while the plants are immature. Other potential problems include oxalate poisoning and off-flavoring of meat and milk.
Most people do not realize the environmental benefits of lawns. Lawns are known to cool the air, reduce soil erosion, remove dust and pollutants (including CO2) from the air, reduce run-off of water and pollutants, create oxygen for humans, and improve soils over time by supplying organic matter. Lawns are also important aesthetically and have been shown to improve human well-being. However, to be 100 percent environmentally friendly, we could never fertilize or water our lawns and only mow with a self-propelled reel mower. Or, we could get rid of our lawn altogether. Neither of these options is particularly appealing for most people. We can, however, have a high quality lawn and reduce our impact on the environment by doing some very simple things at the right times of the year. The following guide will walk you through a series of steps that are important for keeping your lawn looking thick and healthy and at the same time reducing pests and the need for chemicals and other inputs.
La identificacion correcta de los patogenos y de insectos plagas, asi como los trastornos nutricionales y fisiologicos e incluso derivas de herbicidas es esencial para determinar el curso apropiado de accion. Las imagenes incluidas en esta guia representan algunas plagas o problemas comunes que los agricultores pueden encontrar cuando se producen cultivos de solanaceas (tomates, pimientos, berenjena y papas) en Kentucky.
"Fescue toxicosis" is the general term used for the clinical diseases that can affect cattle consuming endophyte-infected tall fescue. Tall-fescue pastures containing ergot alkaloids are responsible for the toxic effects observed in livestock, including hyperthermia (elevated body temperature), gangrene of the extremities, decreased weight gain, and poor reproductive performance. Clinical signs vary depending on the cattle, the environmental conditions, and the level and duration of the exposure. Early clinical signs are often reversible after removal from contaminated pastures or hay.
Pattern, frequency, and amounts of rainfall are important components to plant health. Water is an essential plant component, making up 70 percent to 90 percent of plant mass. During dry seasons and drought conditions, plants become stressed. Growth ceases, nutrient transport slows, and plants wilt as cells become water-deficient. Severe, long-term, or consecutive drought events may cause permanent damage.
Woody plant stress has many causes that might ultimately lead to plant decline. Tree and shrub degeneration is often referred to as a "complex," meaning the condition is usually caused by multiple factors. Typically, one or more primary stresses cause deterioration of plant health, followed by secondary pathogens and/or insects that further decline or destroy plants. Determining causes of decline requires careful examination of plants and growing sites, as well as knowledge of site history. Nevertheless, diagnoses may be difficult, as the original cause(s) of plant stress may be obscure or no longer present. Some of the most common plant stresses are addressed in this publication. A wider range of possible causes of plant stress and decline should be considered during evaluation of woody plant material.
In terms of acreage, sweet corn is the largest commercial vegetable crop grown in Kentucky. Integrated Pest Management (IPM) programs have played an important role in its production and have enabled growers to improve quality and minimize input costs. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are employed in such a way as to minimize environmental risks, economic costs, and health hazards. Pests are "managed" but not necessarily eliminated in order to reduce their negative impact on the crop.
Blueberries are one of the few fruit crops native to North America. Wild blueberries were utilized by Native Americans for making medicines, dyes, and flavorings, as well as for direct consumption. Once a small-scale crop produced within limited regions, blueberries are now grown throughout the United States and the rest of the world.
The National Integrated Pest Management Network defines IPM as "a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health, and environmental risks." One of the key components of IPM is to continually scout and monitor crops to identify problems before they result in significant economic losses. Proper identification of pathogens and insect pests as well as nutritional and physiologic disorders and even herbicide drift is essential to determining the proper course of action. The pictures included in this guide represent some common pests or problems that growers may encounter during apple production in Kentucky.
Many homeowners in Kentucky grow a variety of fruits in their garden and are rewarded for their effort. One distinct advantage homeowners have over commercial orchardists is the diverse ecosystem of the home landscape (vegetable gardens, flower and fruit plantings intermixed with turf and landscape plants). Diversity often reduces the spread of insect and disease organisms and tends to keep their populations at lower, more manageable levels.
Cyanide poisoning of livestock is commonly associated with johnsongrass, sorghum-sudangrass, and other forage sorghums. Choke-cherry or wild cherry, elderberry, and arrow grass are less frequent causes. Young plants, new shoots, and regrowth of plants after cutting often contain the highest levels of cyanogenic glycosides. The risk from potentially dangerous forages may be reduced by following the management practices in this publication.
In developing individual farm mastitis control and treatment strategies, it is often necessary to characterize the types of bacteria that are present on your farm. To answer this question, a microbiological analysis, or milk culture, must be performed on milk samples collected from cows showing clinical or subclinical signs of mastitis. Results of the milk cultures will help identify which bacteria are causing the mastitis. In turn, this information can be used to alter mastitis control, prevention, and treatment options to fit your herd's conditions.
Researchers at the University of Kentucky combined existing disease detection systems to produce a fresh cow examination system that may help producers detect diseases earlier by monitoring subtle changes every day during a cow's fresh period. Compiling daily information about each animal will enable producers to notice changes in health that may otherwise have been overlooked. These records may help producers detect illnesses early, thus reducing the long-term effects (reduced milk production or fertility) and costs (re-treatment, milk loss, or death) of a disease. Learning what diseases are common on a particular farm can focus producers' efforts towards preventive measures specific to their operation. Preventing disease, rather than treating, can save producers time and money and can improve overall cow well-being.
Few plants normally contain high nitrate levels, since under normal growing conditions the nitrates are converted to protein as quickly as they are absorbed from the roots. However, under certain conditions plants can develop dangerously high nitrate levels which can cause nitrate intoxication. Death or abortion may result. Care must be taken to recognize possible toxic forages and manage them appropriately to avoid animal loss.
Iron deficiency is a nutritional deficit that can occur in woody and herbaceous plants in landscapes, nurseries, greenhouses, and production fields. It is most often associated with soils that have neutral or alkaline pH (pH 7.0 or above). Plants that grow best in acidic soils are particularly vulnerable to this condition. In Kentucky, iron deficiency is most commonly observed on pin oak, willow oak, azalea, rhododendron, and blueberry, but other woody plants are also susceptible.
Cole crops are important as a group, particularly when all acreage of cabbage, broccoli, cauliflower, and brussel sprouts are combined. Spring planted crops may have very different problems associated with them compared to fall crops. Integrated Pest Management (IPM) programs fill an important role in production of these crops and have enabled growers to improve quality and minimize input costs. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are employed in such a way as to minimize environmental risks, economic costs, and health hazards. Pests are "managed," but not necessarily eliminated, in order to reduce their negative impact on the crop.
As our population has grown, so have our towns and cities, and this growth has led to an increase in stormwater runoff. Stormwater best management practices help mitigate the impact of stormwater runoff on water quality by reducing pollutant loads through physical, chemical and/or biological processes. One of the most effective BMPs at improving stormwater quality is the stormwater wetland.
Taxus (yew) is an evergreen shrub commonly found in Kentucky landscapes. Numerous conditions can cause these shrubs to exhibit yellowing and browning symptoms. While diseases and insect pests can result in damage, Taxus troubles are often the result of adverse growing conditions. Pinpointing the specific cause requires a thorough examination of the affected shrub, an investigation of the surrounding area, and knowledge of possible stress factors.
Animal mortalities are an expected part of animal production. Depending on the scale of the animal enterprise, animal mortalities can overwhelm the producer with a large number and mass of dead animals. This publication provides guidance to the producer for handling animal mortalities in accordance with Kentucky law.
On-farm composting can provide animal producers with a convenient method for disposing of animal mortalities and also provide a valuable soil amendment. In addition, the finished compost can be stockpiled and reused to help compost other mortalities.
Gardening makes sense! Growing your own vegetables makes you feel self-sufficient and provides fresh, healthful food. Your surplus crop can be frozen, canned, or stored in cool, dry locations. To assure gardening success, start by selecting suitable vegetable cultivars. Planting resistant or tolerant varieties is one of the most effective ways for the home gardener to avoid destructive vegetable diseases.
Large round bales lend themselves very well to the application of mulching rows of vegetables because the bales can be unrolled to peel off layers that are about the right thickness for mulch. An innovative implement that offsets the bale so that it can be unrolled between the rows while the tractor straddles the row can make the practice of mulching with round bales considerably more efficient.
Kentucky dairy producers are adopting compost-bedded pack barns (CBP) as dairy cattle housing at a rapid rate. When properly managed, as an alternative dairy housing system, CBPs may decrease somatic cell count (SCC), increase production, and reduce lameness. Because the system is relatively new, however, many questions remain regarding best management practices and key factors for success. University of Kentucky dairy scientists and agricultural engineers conducted a comprehensive observational study of Kentucky CBPs from October 2010 to March 2011. The goal of this research was to determine key management concepts that determine success or failure in the compost-bedded pack system.
DHIA (Dairy Herd Improvement Association) records are an essential part of dairy herd management for many progressive dairy operations. However, for producers new to DHIA, interpreting the meaning of all this information can be a bit overwhelming. Even producers who have been DHIA members for many years may not fully understand all the value that DHIA records can provide for SCC management. What follows is a description and interpretation of SCC-related information available to dairy producers on DHIA test reports.
Some farmers are reluctant to talk about the environment, but because farms are under increasing review by state and federal regulatory agencies, producers need to be familiar with environmental issues and regulations. Implementing best management practices (BMPs) can help farmers continue to protect the environment and increase productivity.
Kentucky's cattle industry represents the largest beef cattle herd east of the Mississippi, ranking eighth in the nation for number of beef cows. This industry is extremely important to Kentucky's economy. This publication discusses site evaluation strategies, production area management techniques, and a variety of facility types for intensive cattle production that preserve natural resources and improve production.
Extended dry conditions have impacted the corn crop severely in many areas of the state this year. As the condition of the corn crop deteriorates, many have been forced to look at salvage options such as cutting corn for silage and possibly hay for some fields. Due to the extreme weather conditions this year, this publication will focus on valuing drought-stressed corn silage.
As we move into a new era of lower acceptable somatic cell count levels, the prevention and control of mastitis takes on increased importance. For many years, the contagious mastitis pathogens including Staphylococcus aureus, Streptococcus agalactiae and Mycoplasma bovis were the focus of control measures primarily implemented in the milking parlor to stop the spread of these organisms from cow to cow. These contagious organisms often cause high individual somatic cell counts and ultimately high bulk tank somatic cell counts. As these high somatic cell count cows have been culled due to milk marketing regulations and more dairymen have adopted NMC recommended milking procedures, the contagious pathogens are decreasing.
When it comes to minimizing mastitis and lowering somatic cell counts, the area where you have the most control is your milking procedures. Understanding and following proper milking procedures is a critical step to maintaining maximum milk quality.
The compost bedded pack barn is a housing system for lactating dairy cows. It consists of a large, open resting area, usually bedded with sawdust or dry, fine wood shavings and manure composted into place and mechanically stirred on a regular basis.
With proper facilities and education, entreprenuers can successfully produce value-added dairy products on-farm.
Infectious Bovine Keratoconjunctivitis (IBK), also known as pinkeye, is a costly disease for the beef producer. Tremendous losses stem from poor weight gain and loss of appetite in affected animals suffering from visual impairment and ocular pain.
The shade trees and fruit trees that we treasure in our landscapes were originally adapted to growing in forests in close association with other trees. In the forest they can remain small for many years. As soon as there is an opening in the canopy allowing light to reach the forest floor they grow rapidly. This great height allows trees to assume a place of dominance over other plants; their trunks lift their leaves high into the air, allowing them to intercept the maximum amount of sunlight before it reaches other plants. Thus, trees grow tall and provide us with their much-appreciated shade.
This safety bulletin is intended to offer introductory safety training to tobacco workers in conjunction with a farm walk-around. It was written as if you and your workers are standing in or around the object currently being discussed, e.g., a tractor, with you or a designated assistant pointing out the various safety issues listed in the bulletin. It is not meant to be used as a stand-alone bulletin, especially just in a room, unless you have already gone through the walk-around and are reviewing points or having a discussion. It must be used out by the barn, equipment, or other subject being discussed.
Switchgrass (Panicum virgatum L.) is a warm-season, perennial bunch-type grass native to the North American Tallgrass Prairie. It has been investigated as a renewable energy crop due to its high productivity across a wide geographic range including various environmental conditions and soil types. Switchgrass has also been used for erosion control, summer grazing in pasture and hay systems for cattle, native prairie restoration, wildlife habitat, fiber production, and as an ornamental grass.
Roses have many landscape uses. They can be placed as accent plants or used to form hedges or ground covers. They offer a rainbow of colors and a variety of forms and fragrances, and their sizes range from miniatures to tall climbing plants. Roses may be grown under many climatic and soil conditions and, with care, thrive and produce flowers for many years.
We generally view gardening as a wholesome activity that enhances our environment. But pesticides, fertilizers, and erosion from gardens and landscapes can contaminate lakes, streams, rivers, oceans, and groundwater. Since the quality of our water resources affects our quality of life, we must learn how gardening practices can contribute to water contamination and how to reduce the threat to water quality.
Management of woody plant diseases usually combines preventative and curative practices, including a focus on plant health, sanitation, cultivar selection, and pesticides.
Staphylococcus aureus is an important bacterial cause of contagious mastitis on dairy farms worldwide. More importantly, it is often at the root of chronically high somatic cell counts, recurrent clinical mastitis, and damaged mammary gland tissue. It is considered to be a contagious udder pathogen that spreads within and between cows during milking. Because it is often subclinical (milk looks normal but with a potentially high somatic cell count), infected animals pose a risk of infection to herd mates during each milking.
An enhanced vegetative strip is a best management practice that can be installed to protect surface waters from pollution produced by animal production facilities. Most people think of a vegetative strip as a grassed area or waterway, but when intentionally installed and properly managed, an EVS can be much more effective than a simple grassed filter strip. If properly managed, enhanced vegetative strips can be used to trap, treat, and absorb pollutants, which can be removed from the designated area by harvesting or grazing.
Sweetpotato (Ipomoea batatas L.) is a member of the morningglory or Convolvulaceae family. Sweetpotatoes have their origins in tropical America, with early remains having been found in Panama, Peru and Mexico. A perennial plant in their native regions, they are typically killed by frost when grown in a temperate climate. Sweetpotatoes are true roots and not tubers as is the case with the Irish Potato (Solanum tuberosum). Because they are true roots they will continue to grow and enlarge as long as the plant continues to grow.
Each year producers must decide whether to store or sell their crop at harvest. Market prices are important in guiding producers on whether to store priced grain for future delivery (referred to as a storage hedge), store unpriced grain, or sell. Generally, producers know more about deciding to sell or store unpriced grain than using the storage hedge. This publication explains how a storage hedge works, when to use it, and risks and costs involved. (See glossary for definition of terms.)
Equine viral arteritis (EVA) is a contagious disease of horses and other equine species caused by equine arteritis virus (EAV) that is found in horse populations in many countries. It was first isolated and identified in 1953 from the lung of an aborted fetus with characteristic pathologic changes in the smaller arteries, which is how the disease got its name.
Gardeners have long made and used compost to improve garden soil. Composting plant and vegetable matter is an important way to reduce the waste burned or dumped in landfills. Yard wastes and vegetable scraps can make up as much as 20 percent of household garbage. Composting effectively recycles that waste into valuable organic matter that can be used as soil amendments.
The concept of stockpiling is pretty straightforward, but the challenge each year is to determine the likelihood that this practice will be profitable given the economic and agronomic conditions present at mid-summer. This practice can yield significant benefits, but it also carries significant costs. These benefits and costs must be quantified and compared to assess the overall profitability of the practice.
Soybean cyst nematode (SCN) is the most serious disease pest of soybean in the United States (and Kentucky) and results in an estimated $1 billion in losses annually. SCN is a microscopic roundworm (Heterodera glycines) that feeds on root of soybean and reduces its capacity to absorb water and nutrients. Yield losses of 30% or more are common where SCN-susceptible soybean varieties are grown and SCN levels are high. SCN was first discovered in Kentucky in 1957 in Fulton County but is now found in every Kentucky county in which soybean is grown commercially.
Nearly all climate science experts agree that global warming is occurring and that it is caused primarily by human activity. Regardless of what you may read on blogs or in the media, there is no meaningful scientific controversy on these points. The future impacts of global warming are difficult to predict, but the changes caused by greenhouse gases are expected to increasingly affect Kentucky agriculture.

Cattle maintain their body temperature in winter by burning more calories, which requires them to consume more feed. Livestock producers use wooded areas to provide protection for cattle from wind and low temperatures. That protection enables the cattle to conserve energy and eat less. Using wooded areas for winter feeding makes practical sense, but producers need to consider several environmental issues when planning for it.
Proper identification of pathogens and insect pests as well as nutritional and physiologic disorders and even herbicide drift is essential to determining the proper course of action. The pictures included in this guide represent some common pests or problems that growers may encounter when producing solanaceous crops (tomatoes, peppers, eggplant, and potatoes) in Kentucky.
Ruminal tympany, or bloat, can result in lost animal performance and in severe cases, death. It occurs as a result of a buildup of fermentation gases in the rumen. Bloat may be categorized as frothy bloat, which is caused by the formation of a stable foam in the rumen, or free gas bloat, which is due to excessive production of gaseous compounds from fermentation or as a result of an obstruction preventing the escape of gas compounds. Legume bloat is a frothy bloat condition.
Actively creating a riparian buffer typically consists of six steps: site assessment, planting plan development, site preparation, species selection, planting, and protection and maintenance.
When you're trail riding, you need to be aware of safety, not only for yourself and the horse, but also as a courtesy for other trail users. You should follow all general precautions about safe riding, but also follow practices that apply specifically to trails, whether you're riding alone or in a group, for a short or long distance, or for fun or competition.
Kentucky and surrounding states are known for grass pastures and horses. Pastures supply nutrients, provide hoof support for exercise, control erosion, and add to the aesthetic value of horse farms. The ability to establish and manage horse pastures is therefore important to horse owners.
Wobbler syndrome, or cervical vertebral malformation (CVM), is a devastating disease that can affect a horse's neurologic and musculoskeletal systems. It is a structural narrowing of the spinal canal due to a variety of vertebral malformations and leads to spinal cord compression. As a result, horses exhibit clinical signs of spasticity, ataxia, and lack of coordination.
Kentucky is generally well suited for growing nut trees. Northern pecans, black walnuts, heartnuts, hickory nuts, hardy Persian walnuts (Carpathian strain), American hazelnuts, and Chinese chestnuts all grow well in the state. Although most nut trees are grown by hobbyists and backyard gardeners, several varieties appear to have potential for commercial production, particularly some of the USDA pecan selections and some Chinese chestnut varieties.
Horse owners, managers, and handlers can help to maintain the health of their animals by studying their behavior through observation and inspection, and should be able to accurately determine important measurements such as temperature, pulse, respiration, and mucous membrane color through a clinical examination. Having this information about your horse can be critical if the animal is ill or injured and you need to supply these details to your veterinarian.
The Corn and Soybean Production Calendar was developed to help producers prioritize and schedule work events in a timely fashion on the farm. Weather events and equipment breakdowns rarely follow an organized schedule. However, if other practices within the farming operation are prioritized, perhaps a producer can better address the emergencies that will occur.
In Kentucky, cattle on pastures are often watered by streams. Although this practice solves water requirements for cattle, providing livestock free access to streams and riparian areas can lead to a contaminated water supply and damaged ecosystems. A better solution is to implement riparian buffers with limited access points to streams or provide alternative water sources. This practice can protect water quality, increase herd production, and provide other landowner benefits. The purpose of this publication is to explain the role of riparian areas and how they can benefit the livestock producer, the herd, and the environment.
Choosing the environment in which lactating dairy cows will spend the majority of their time is an important decision for dairy producers. This choice has considerable influence on productivity, health, milk quality, reproduction, animal well-being, and farm profitability. Innovative dairy producers have introduced a variation on the loose-housing system, generally referred to as a compost-bedded pack barn. Its key component is a large, open resting area, usually bedded with sawdust or dry, fine wood shavings.
Historically, wheat planting in Kentucky has involved tillage. With conventional tillage practices, most residues from the previous crop are cut and buried prior to seeding wheat. No-till wheat planting eliminates tillage and reduces soil erosion, particularly on sloping soils, as well as reducing labor, machinery, and energy costs.
Most farmers in Kentucky can identify with a myriad of problems associated with mud forming around high traffic areas, including areas around horse and cattle waterers, feed bunks, round bale feeders, walk paths and gate entrances. Mud is usually a result of animals congregating in and around these areas, but increased traffic can enhance the problem. In many cases, finding solutions to mud problems on farms is not the issue--the issue is determining how to make solutions economical.
Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of integrated pest management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are used to minimize environmental risks, costs, and health hazards. Pests are managed to reduce their negative impact on the crop, although pests are rarely eliminated.
The average Canada goose produces more fecal waste than a dairy cow on a per-weight basis. In addition, gaggles of resident Canada geese have been associated with problems of over grazing. Having large amounts of fecal waste around a riparian area that has limited vegetation can lead to the runoff of nutrients, sediment, and pathogens, which can contaminate ponds, lakes, and streams in Kentucky.
This publication is written for those who wish to maintain their lawn with minimal inputs. Low-maintenance lawn care offers certain benefits, such as minimal pesticide use, reduced fertilizer input, less need for irrigation, and reduced mowing frequency. However, when choosing a low-maintenance approach, recognize that the lawn will not offer the same dark green, uniform sward of turf that is seen under a high-maintenance lawn-care program.
The corn grown in Kentucky is used mainly for livestock feed and as a cash crop. As a cash crop sold from the farm, corn ranks third behind tobacco and soybeans but is the number one row crop in terms of acreage. Because the cost of producing an acre of corn is high and the value per bushel has declined in recent years, producers must manage and market their corn crop more carefully for adequate profits. The goal of this publication is to serve as a guide for corn production strategies that focus on efficient use of resources and provide the principles and practices for obtaining maximum, profitable corn yields.
Kentucky has a long record of good grape production. As a home fruit crop or commercial crop, grapes have many benefits. Grapevines are relatively inexpensive and easy to propagate. They reach full bearing potential in four years and bear annually. The many varieties of grapes can be consumed fresh or used to make grape juice, jams, jellies, and wine. Grapes are also easy to manage. Vines are trained on trellises or arbors and easily can be sprayed using small equipment for control of insects and diseases.

Cover crops have long been used to reduce soil erosion, add organic matter to improve the soil, and provide some winter and early spring grazing. With the develop ment of no-till cropping systems, cover crops were recognized for their ability to provide moisture-conserving residues as well as nitrogen for the succeeding crop. Recent concern for water quality has provided additional reasons to use cover crops. Cover crops take up and hold nutrients, especially nitrogen, that were not used by the previous crop. Because they remove water from the soil, they may reduce the risk of nutrients and pesticides moving through the soil. Cover crops may reduce weed problems and the need for herbicides by competing with them for space and nutrients and by providing a mulch to cover the soil surface. Some also release chemicals that suppress weed growth and may reduce populations of soil-borne plant pathogens.

Grading and marketing lambs is the culmination of a year-long program. Decisions concerning marketing and the management of lambs still on the farm markedly affect the success of a sheep producing program. By its prices for different types of lambs, the market sends signals about what should be produced. Managers must look at price trends over time and compare them with production costs. Your income is the true measure of success in any production program. The steps to a good marketing program include analyzing both the market and the product you plan to market.

Proven management practices such as castrating, dehorning, pregnancy examination, controlling parasites, implanting, vaccinating, etc. are essential if profits are to be realized in beef herds. Although most practices are relatively simple, they cannot be done easily without some type of restraining equipment which will prevent injury to both man and animal. The absence of cattle handling facilities probably contributes more than anything else to failure to perform these money-making procedures.
