Purebred are those animals that have been bred-up to purebred status as a result of using full blood animals to cross with an animal of another breed. Artificial breeding via artificial insemination or embryo transfer is often used in sheep and cattle breeding to quickly expand, or improve purebred herds.
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 ...
The French saddle horse is an excellent example as is the Irish Sport Horse, the latter being an unusual combination between a Thoroughbred and a draft breed. The American Quarter Horse was developed early in the 18th century, mainly for quarter racing (racing ¼ of a mile). Colonists did not have racetracks or any of the trappings of Europe ...
The restructured French Herd Book is described as having a third section called certified purebred (race pure certifié in French) intermediate between the first two for recording animals that do not comply with the breed standard (for example incorrectly coloured hair in certain places), have double muscling genes, or are polled. [26]
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.
Animal 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. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
Today, the standards for defining and registration of different breeds vary. Sometimes, purebred horses are called "Thoroughbreds", which is incorrect; "Thoroughbred" is a specific breed of horse, while a "purebred" is a horse (or any other animal) with a defined pedigree recognized by a breed registry.

Braunvieh, a dairy breed [1] with high milk production and little milk fat. A breed is a specific group of breedable domestic animals having homogeneous appearance (), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species.
