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.
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 ...
Crossbreeding, the process of breeding an animal with purebred parents of two different breeds, varieties, or populations; Mating; Preservation breeding, a selection practice to preserve bloodlines; Selective breeding, an animal selection practice to encourage chosen qualities; Smart breeding, a plant selection practice to encourage chosen ...
The genetic differences both within and between populations, species, or other groups of organisms. It is often visualized as the variety of different alleles in the gene pools of different populations. genetics The field of biology that studies genes, genetic variation, and heredity in living organisms. genic balance
Some registries, such as American Kennel Club, may include a record of the absence of certain genetic defects, known as a certification, in an individual dog's record. For example, the German Shepherd Dog national breed club in Germany recognizes that hip dysplasia is a genetic defect for dogs of this breed. Accordingly, it requires all dogs to ...
Animal breeding as an ancient human occupation, can be traced back to domestication and dates back to at least 14 thousand yrs ago. The modern processes of purebred breeding evolved between the late 18th century and the late 20th century, influenced significantly by advancements and increased understanding of genetics and eugenics.
The education of fish biologists paid less attention to quantitative genetics and breeding plans. [25] Another was the failure of documentation of the genetic gains in successive generations. This in turn led to failure in quantifying economic benefits that successful selective breeding programs produce.
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 smell (), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species.
