Abstract: Rumination time (RT) was an important indicator to evaluate health in dairy cattle. Recent researches showed that daily RT at estrus significantly reduced compared with that on nonestrus days. Based on this results, RT could be acted as a new method of heat detection in dairy cattle. In the article, the relation between daily RT and estrus, as well as the application prospects of the potential heat detection method, were reviewed in order to improve the production efficiency of dairy cattle.

Key words: dairy cattle; rumination time; heat detection
