Rut (mammalian reproduction) : ウィキペディア英語版 | Rut (mammalian reproduction)
The rut is the mating season of ruminant animals such as deer, sheep, camel, goats, pronghorn and Asian and African antelope. During the rut (also known as the rutting period and in domestic sheep management as tupping), males often rub their antlers or horns on trees or shrubs, fight with each other, wallow in mud or dust, self-anoint and herd estrus females together. The rut in many species is triggered by shorter daylengths. For different species, the timing of the rut depends on the length of the gestation period (pregnancy), usually occurring so the young are born in the spring. This is shortly after new green growth has appeared thereby providing food for the females, allowing them to provide milk for the young, and when the temperatures are warm enough to reduce the risk of young becoming hypothermic. ==Cervidae==
