Artificial breeding via artificial insemination or embryo transfer is often used in sheep and cattle breeding to quickly expand, or improve purebred herds. Embryo transfer techniques allow top quality female livestock to have a greater influence on the genetic advancement of a herd or flock in much the same way that artificial insemination has ...
Breeding stock is a group of animals used for the purpose of planned breeding. 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 superior abilities in a given area of endeavor. For ...
Most mating done by purebred breeders is linebreeding which is the mating of animals of different families within the same breed to bring in desirable traits that are not present in the original animals. [11] Unlike commercial producers, purebred breeders cannot use crossbreeding as it would dilute the breed's purity, resulting in a mixed breed ...
Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed. Planned matings can be used to produce specifically desired characteristics in domesticated horses. Furthermore, modern breeding management and technologies can increase the rate ...
One example of this change in breeding goals is the pronounced sloped back in the modern German Shepherd breed, compared to the straight back of working pedigrees. The Shar Pei is an example of how differing breed standards can influence the direction breeders take a dog and which traits are exaggerated.
One aim of modern human behavioral ecology is to determine how ecological and social factors influence and shape behavioral flexibility within and between human populations. Among other things, HBE attempts to explain variation in human behavior as adaptive solutions to the competing life-history demands of growth, development, reproduction ...
Purebred dogs have been, for the most part, artificially created from random-bred populations by human selective breeding with the purpose of enhancing desired physical, behavioral, or temperamental characteristics. Dogs that are not purebred are not necessarily a mix of such defined breeds. [61]
