Breed

– Breeding: selection by breeders
– Breeders establish a breed by selecting animals with desired qualities.
– Selected animals become foundation stock for the breed.
– Breeders mate desirable animals to pass on characteristics through selective breeding.
– The process is guided by a breed standard describing desirable traits.
– Breeders aim to enhance the breed model through selective breeding.

– Breed characteristics
– Breed traits are inherited and passed down in purebred animals.
– Animals of the same breed share genetic characteristics from the foundation animals.
– Breeders select animals with desirable traits to maintain and develop them.
– Undesirable traits or genetic defects are avoided in breeding.
– Sufficient population size is crucial to maintain breed parameters without forced inbreeding.

– Breed formation
– Breeds are formed through genetic isolation and selective breeding.
– No universally accepted scientific definition of a breed exists.
– Breeds are groups of animals with homogeneous appearance and behavior.
– Breeds are not biologically verifiable classifications but rather consensus-based.
– Breeding true, or passing predictable traits to offspring, is essential for a breed.

– Native breeds
– Domestic animal breeds vary between countries and nations.
– Breeds originating in a specific country are known as native breeds.
– Native breeds reflect the characteristics and adaptability to their home environment.
– Preservation of native breeds is important for biodiversity and cultural heritage.
– Native breeds often possess unique traits suited to local conditions.
