Cattle feedlot in Colorado, United States. Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, or other products.It includes day-to-day care, management, production, nutrition, selective breeding, and the raising of livestock.
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 ...
Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species. Bos indicus (or Bos taurus indicus) cattle, commonly called zebu, are adapted to hot climates and originated in the tropical parts of the world such as India, Sub-saharan Africa, China, and Southeast Asia.
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.

An American breeder, Richard Gradwohl, has developed eighteen different strains of miniature cattle. [3] Miniature Galloway, Hereford and Holstein have been bred. [2]: 245 [3] In the United States, small zebuine cattle deriving from stock imported from Brazil, the Dominican Republic and Sweden may be registered as "Miniature Zebu"; [2]: 245 Similar cattle are known as "Nadudana" in Australia.

Pig farming, pork farming, pig production or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food (e.g. pork: bacon, ham, gammon) and skins.

Polled strains have been developed of many cattle breeds which were originally horned. This has usually been done by crossing with naturally polled breeds, most commonly Angus and Galloway cattle. For example, polled Jersey cattle originated in Ohio sometime prior to 1895. Two strains were developed, the first to appear being founded by crosses ...
