Body Condition Scoring Ewes
8/25/2017 (new)

Body condition scoring is a system of classifying breeding ewes on the basis of differences in body fat. While it is subjective, with practice it can be accurate enough to indicate the nutritional status of individual ewes as well as the entire flock. Thus, it allows the shepherd to identify, record, and adjust the feed intake of ewes determined to be thin, in average flesh, or fat. In the long run, this can save money for producers and/or prevent problems attributable to ewe condition. | ASC-228

Keeping and Using Flock Performance Records
12/17/2014 (new)

Performance records serve as the cornerstone of any good livestock management program. Unfortunately, the task of collecting, maintaining and using performance records is the one area of livestock production in general that gets the least attention. This fact sheet provides ten reasons why all sheep producers need to keep performance records on their flocks. Then, some ways of maintaining and using those records are discussed. | ASC-221

Crossbreeding Considerations in Sheep
12/16/2014 (new)

Crossbreeding is the mating of individuals from different breeds. To a certain extent, it is a simple concept, but embarking upon a crossbreeding program, in sheep or any other livestock species, involves long-term decisions. The primary benefits of a crossbreeding program are heterosis and breed complementarity. | ASC-224

Inbreeding in Sheep
12/16/2014 (new)

Inbreeding is broadly defined as the mating of individuals that are related. Strictly speaking, however, all animals within a breed are related. So, in a sense, every purebred sheep producer practices some degree of inbreeding. In most cases this relationship is very slight. Therefore, inbreeding is more practically defined as the mating of individuals more closely related than the average of the breed. This practice includes mating brother to sister, sire to daughter and son to dam. | ASC-223

Sheep Breeding: Heritability, EBVs, EPDs, and the NSIP
12/16/2014 (new)

Genetic improvement in a flock depends on the producer's ability to select breeding sheep that are genetically superior for traits of economic importance. This is complicated by the fact that an animal's own performance is not always a true indicator of its genetic potential as a parent. | ASC-222

Basic Sheep Genetics
12/16/2014 (new)

Genetics is the science of heredity. It seeks to explain differences and similarities exhibited by related individuals. The application of genetics to livestock improvement is known as animal breeding. The objective of this fact sheet is to provide a refresher course on basic genetics and to show how knowledge of genetics can be used to improve sheep production. | ASC-220
