Abstract

Abstract:

Automation and information are the important development directions of technologies in dairy industry. To break through the bottleneck of automatically monitoring technology for quiet estrus cows, the regulation pattern of body temperature has become another study focus related to reproductive cycle of dairy cattle after the regulation pattern of activity quantity. Both age and diurnal variation characteristics of body temperature in cow have been shown. Meanwhile, the regulation pattern of body temperature related to estrus, pregnancy and delivery on reproductive cows was observed, and the regulation patterns varied with different measurement sites. Among these detection sites, the regulation pattern of viginal temperature plays a more instructive role in marking reproductive behavior for its close relationship to reproductive activities. Additionally, the body temperature was usually affected by reproductive hormones, environmental conditions, diseases, measurement methods and other factors. The premises of making better use of body temperature data are scientific analysis of factors affecting body temperature and construction of an automatic collection technology and database for it, which will promote the automation, elaboration and intelligentization of both cow reproduction and health management.
