An ox (pl.: oxen), also known as a bullock (in British, Australian, and Indian English), [1] is a large bovine, trained and used as a draft animal. Oxen are commonly castrated adult male cattle, because castration inhibits testosterone and aggression, which makes the males docile and safer to work with. Cows (adult females) or bulls (intact ...
A castrated male steer, occasionally a female or in some areas an intact bull that is trained and kept for draft or riding purposes is called an ox (plural oxen); ox may also be used to refer to some carcass products from any adult cattle, such as ox-hide, ox-blood, oxtail, or ox-liver. [3] A springer is a cow or heifer that is close to calving ...
Livestock grazing comparison is a method of comparing the numbers and density of livestock grazing in agriculture. Various units of measurement are used, usually based on the grazing equivalent of one adult cow, or in some areas on that of one sheep. Many different schemes exist, giving various values to the grazing effect of different types of ...
This simple method is sometimes used for cattle. The number of animal units represented by one or more head of cattle may be calculated by dividing their total body mass in kg by 454 (or dividing their weight in pounds by 1000). Thus an 800-pound steer would be considered equivalent to 0.8 animal units. [4] Estimation based on metabolic body size.
The female counterpart to a bull is a cow, while a male of the species that has been castrated is a steer, ox, [2] or bullock, although in North America, this last term refers to a young bull. [citation needed] Use of these terms varies considerably with area and dialect. Colloquially, people unfamiliar with cattle may also refer to steers and ...
Goats and sheep were domesticated in multiple events sometime between 11,000 and 5,000 years ago in Southwest Asia.

The High Plains ecology region is designated by 25 on this map. Childress County, Texas, June 1938.. The High Plains are a subregion of the Great Plains, mainly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains.
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]
