Vitamin Supplementation for Beef Cattle

7/18/2022 (new)
Authors: Les Anderson, Darrh Bullock, Kevin Laurent, Jeff Lehmkuhler, Katherine VanValin

Beef cattle have defined requirements for vitamins. In some instances, vitamin supplementation may be necessary to avoid deficiencies. Vitamins are classified into two categories: water-soluble and fat-soluble. Water-soluble vitamins include the B vitamins, such as riboflavin, thiamin, and niacin, as well as vitamin C. Fat-soluble vitamins include vitamins A, D, E, and K. Supplementation for beef cattle generally focuses on vitamins A and E. This is because the rumen microbes synthesize the water-soluble vitamins and vitamin K in sufficient quantities to avoid deficiencies. Vitamin D requirements can often be met by exposure to the sun and would therefore only be of concern for cattle in confinement housing.

The Kentucky Beef Book, 2021

3/23/2021 (major revision)
Authors: Les Anderson, Michelle Arnold, Darrh Bullock, Kenny Burdine, Roy Burris, Ben Crites, Jimmy Henning, Steve Higgins, Steve Isaacs, Kevin Laurent, Jeff Lehmkuhler, Lee Moser, Gregg Rentfrow, Kylie Schmidt, Ray Smith, Chris Teutsch, Lee Townsend, Katherine VanValin, Paul Vijayakumar

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.

Alternative Protein Sources for Cattle

7/2/2020 (new)
Authors: Les Anderson, Darrh Bullock, Darrell Johnson, Kevin Laurent, Jeff Lehmkuhler, Katherine VanValin

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?

Feeding Distillery Stillage to Beef Cattle

6/1/2020 (new)
Authors: Les Anderson, Darrh Bullock, Kevin Laurent, Jeff Lehmkuhler

The growth of the bourbon industry has provided an increase in distillery byproduct feedstuffs that can be utilized by cattle as a source of energy and protein. Learning the nutritional characteristics of these feedstuffs will facilitate proper feeding, allowing for improved cattle performance.

Weaning Beef Calves

9/17/2019 (new)
Authors: Les Anderson, Michelle Arnold, Darrh Bullock, Jeff Lehmkuhler

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.

Authors: Glen Aiken, Les Anderson, Darrh Bullock, Roy Burris, Lowell Bush, J.R. Bussard, Andrew Foote, Ben Goff, David Harmon, V.B. Holder, Isabelle Kagan, Nicole Kenney, D.H. Kim, S.E. Kitts, Jim Klotz, Anne Koontz, Jeff Lehmkuhler, Kyle McLeod, Jim Strickland, Eric Vanzant, Bill Witt

The intent of this report is to provide highlights of our research and extension activities. We have a vested interest in the beef industry in the state and nation, and hope this report provides a window into our programs. We believe that after viewing this report, a greater appreciation will be garnered with respect to our involvement in the multiple fields of study related to beef production. The faculty, staff and student activities are advancing our understanding of basic science principles of livestock production as well as applied research that producers and the industry can benefit from immediately, as well as in the future. Extension educational programs, on-farm demonstrations, and other activities aid in transferring this knowledge to producers, allowing for increased awareness and adoption of management change.
