Domestic sheep reproduction. A cross-bred ewe suckles her lamb, which was the first of the 2008 spring lambing at a farm in Coventry, England. Domesticated sheep are herd animals that are bred for agricultural trade. A flock of sheep is mated by a single ram, which has either been chosen by a farmer or, in feral populations, has established ...
List of mammalian gestation durations. This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically ...
These cycles are widely variable in duration and frequency depending on the species. [2] Some animals may display bloody vaginal discharge, often mistaken for menstruation. [3] Many mammals used in commercial agriculture, such as cattle and sheep, may have their estrous cycles artificially controlled with hormonal medications for optimum ...
Appearance. European mouflon have a body length of up to 120 cm, a shoulder height of 90 cm, a weight of 25 to 40 kg for ewes, 35 to 55 kg for the ram. The European mouflon has a smooth hairy coat, the rams are fox red-brown in the summer, usually with a whitish saddle patch, the ewes are brownish. Both sexes are darker in winter.

O. cervina Desmarest. O. montana Cuvier[5] The bighorn sheep (Ovis canadensis) [6] is a species of sheep native to North America. [7] It is named for its large horns. A pair of horns may weigh up to 14 kg (30 lb); [8] the sheep typically weigh up to 143 kg (315 lb). [9]
Rut (mammalian reproduction) The rut (from the Latin rugire, meaning "to roar") is the mating season of certain mammals, which includes ruminants such as deer, sheep, camels, goats, pronghorns, bison, giraffes and antelopes, and extends to others such as skunks and elephants. The rut is characterized in males by an increase in testosterone ...
The duration of this period varies between species. For most species, the amount a fetus grows before birth determines the length of the gestation period. Smaller species normally have a shorter gestation period than larger animals. [2] For example, a cat's gestation normally takes 58–65 days while an elephant's takes nearly 2 years (21 ...
