Gestation length is an indicator of the probability of dystocia. The longer a calf is in utero the larger it will be at birth and the greater the chance of it having dystocia. It also gives the cow a larger postpartum interval between pregnancies. A shorter gestation length is usually preferred because of this. [2]
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.
Sheep have a breeding season (tupping) in the autumn, though some can breed year-round. [1] As a result of the influence of humans on sheep breeding, ewes often produce multiple lambs. This increase in lamb births, both in number and birth weight, may cause problems with delivery and lamb survival, requiring the intervention of shepherds. [2]

Sheep and goats are found primarily in Eurasia, though the Barbary sheep and the ibex form part of the African fauna. The muskox is confined to the arctic tundra. Several bovid species have been domesticated by human beings. The domestication of goats and sheep began 10 thousand years ago, while cattle were domesticated about 7.5 thousand years ...
In older English sources such as the King James Version of the Bible, cattle refers to livestock, as opposed to deer which refers to wildlife. Wild cattle may refer to feral cattle or to undomesticated species of the genus Bos. When used without a qualifier, the modern meaning of cattle is usually restricted to domesticated bovines. [15]
A Wiltshire Horn ewe and her triplets. The Wiltshire Horn is a breed of domestic sheep originally from Wiltshire in southern England raised for meat. [1] The breed is unusual among native British breeds, for it has the unusual feature of moulting its short wool and hair coat naturally in spring, obviating the need for shearing. [2]
Gestation crates, used on modern pig-production facilities, commonly referred to as factory farms. A gestation crate, also known as a sow stall, is a metal enclosure in which a farmed sow used for breeding may be kept during pregnancy. [1] [2] [3] A standard crate measures 6.6 ft x 2.0 ft (2 m x 60 cm). [4] [5]
