![]() Such animals can be recorded with a breed registry, the organisation that maintains pedigrees and/or stud books. By "breeding the best to the best", employing a certain degree of inbreeding, considerable culling, and selection for "superior" qualities, one could develop a bloodline or " breed" superior in certain respects to the original base stock. Opposite to the practice of mating animals of different breeds, purebred breeding aims to establish and maintain stable traits, that animals will pass to the next generation. Mating animals of the same breed for maintaining such breed is referred to as purebred breeding. While breeding animals is common in an agricultural setting, it is also a common practice for the purpose of selling animals meant as pets, such as cats, dogs, horses, and birds, as well as less common animals, such as reptiles or some primates. For example, when breeding swine for meat, the "breeding stock should be sound, fast growing, muscular, lean, and reproductively efficient." The "subjective selection of breeding stock" in horses has led to many horse breeds with particular performance traits. When individuals are looking to breed animals, they look for certain valuable traits in purebred animals, or may intend to use some type of crossbreeding to produce a new type of stock with different, and presumably super abilities in a given area of endeavor. ![]() The scientific theory of animal breeding incorporates population genetics, quantitative genetics, statistics, and recently molecular genetics and is based on the pioneering work of Sewall Wright, Jay Lush, and Charles Henderson.īreeding stock is a group of animals used for the purpose of planned breeding. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has revolutionized livestock production throughout the entire world. For other uses, see Animal breeding (disambiguation).Īnimal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. For breeding of animals in the wild, see Breeding in the wild. This article is about breeding of animals by humans.
