Therefore, there is a question, and often heated controversy, as to when or if a breed may need to allow "outside" stock in for the purpose of improving the overall health and vigor of the breed. Because pure-breeding creates a limited gene pool, purebred animal breeds are also susceptible to a wide range of congenital health problems. [3]
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 ...
[10] In all cattle species, a female twin of a bull usually becomes infertile due to intrauterine exposure to high testosterone levels. She is functionally a partial intersex, and is commonly called a freemartin. A wild, young, unmarked bull is known as a micky in Australia. [7] An unbranded bovine of either sex is called a maverick in the US ...
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 ...
A breeder can breed purebred pets such as cats or dogs, livestock such as cattle or horses, and may show their animals professionally in assorted forms of competitions. In these specific instances, the breeder strives to meet standards in each animal set out by organizations. A breeder may also assist with breeding animals in the zoo.
Puppies from mills are usually sold as purebred dogs in an attempt to attract the higher prices associated with purebreds. However, due to the indiscriminate breeding practices of puppy mills, the dog may not actually be a purebred puppy. [16] A high population of puppies from mills are inbred due to uncontrolled breeding. [17]
In late 2010, the Conservancy released a definition of "heritage cattle", to follow their earlier heritage turkey description. Requirements for heritage cattle breeds include having a long history in the US, being purebred, and being a true genetic breed. Specifications for heritage milk and beef, as well as products made from them, were also ...
Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. [5] When bred together, individuals of the same breed pass on these predictable traits to their offspring, and this ability – known as "breeding true" – is a requirement for a breed.
