Female cattle in oestrus may mount any adult cattle, especially a bull (fertile male) if one is present, but they will also mount castrated males or other females. A bulling female will often also be mounted by other cattle, both male and female (only fertile males are usually capable of mating). A dominant bull will defend the bulling female from being mounted by other cattle. Bulling is used by farmers to recognise oestrus, which is important to determine the fertile period when cows may be artificially inseminated.〔 Care is needed to identify whether the animal in oestrus is the one mounting or being mounted, and of course sometimes ''both'' animals may be in oestrus. Mounting behaviour is also sometimes seen between adult cattle in the absence of a female in oestrus. ==See also== *List of mammals displaying homosexual behavior 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bulling (cattle)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
