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 ...
The lives of the only pair of breeding ospreys on the south coast of England are being showcased in a series of videos released by conservationists. A reintroduction programme began in Poole ...
Growth of the ABBI increased the popularity of breeding cattle specifically for their traits as bucking stock, and organized livestock breeding exploded for both genders of cattle. [7] The ABBI developed futurity programs for the bulls as it grew. A futurity is an event for younger bulls where the bull is judged solely on his own performance.
However, beef cattle can also be bred through artificial insemination, [1] depending on the cow and the size of the herd. Cattle are normally bred during the summer so that calving may occur the following spring. [1] However, cattle breeding can occur at other times of year. Depending on the operation, calving may occur all year round.
After the Second World War, artificial insemination became common in cattle and pig breeding. As a result of these developments, a limited number of transboundary commercial breeds, such as the Holstein cow and Large White pig , have become very widespread and nowadays increasingly dominate livestock production globally.

Exports of cattle and semen were for a while an important economic resource for the island, and in the early 20th century, a large number of Guernsey cattle were exported to the United States. [5] The Guernsey breed is on the watch list maintained by the American Livestock Breeds Conservancy, with fewer than 2,500 annual registrations in the U ...
Cross-fostering is a technique used in animal husbandry, animal science, genetic and nature versus nurture studies, and conservation, whereby offspring are removed from their biological parents at birth and raised by surrogates, typically of a different species, hence 'cross.'
