Cattle have some 22,000 genes, of which 80% are shared with humans; they have about 1000 genes that they share with dogs and rodents, but not with humans. Using this bovine "HapMap", researchers can track the differences between breeds that affect meat and milk yields. [65]
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.
A fresh cow is a dairy term for a cow (or a first-calf heifer in few regions) who has recently given birth, or "freshened." The adjective applying to cattle in general is usually bovine. The terms bull, cow and calf are also used by extension to denote the sex or age of other large animals, including whales, hippopotamus, camels, elk and elephants.
The Holstein is arguably the most well-known and easily recognized breed of cattle on Earth, and their appearance is an iconic component of many depictions of pastoral life in art and media. Holsteins have very distinctive markings, usually black and white or red and white in colour, typically exhibiting piebald patterns. [4]
Crossbreeding through the use of Limousin terminal sires in purebred British breed cow herds allows the complementary traits of higher marbling and fat cover provided by the British breed cows, and required or preferred by some markets, [74] [75] to be combined with the higher yield and feed conversion efficiency of Limousin sires.
The Brahman is an American breed of zebuine-taurine hybrid beef cattle. It was bred in the United States from 1885 using cattle originating in India, imported at various times from the United Kingdom, India, and Brazil. These were mainly Gir, Guzerá and Nelore stock, with some Indu-Brasil, Krishna Valley and Ongole. The Brahman has a high ...
If it was a cow's first time calving, she will take longer to re-breed by at least 10 days. [4] 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]
Beefalo constitutes a hybrid offspring of domestic cattle (Bos taurus), usually a male in managed breeding programs, and the American bison (Bison bison), usually a female in managed breeding programs. [1] [2] The breed was created to combine the characteristics of both animals for beef production.
