摘要
在奶牛养殖中,为增加牛奶产量,使奶牛及时受孕、产犊并提高泌乳期是非常重要的,而要达到上述目的,正确、高效地预测以及检测奶牛的发情期,并适时配种尤为关键。因此,奶牛发情的及时和准确识别则变得举足轻重,在牛群管理中具有重要地位。传统的奶牛发情检测方法愈加不能满足现代化奶牛养殖场的需求,基于微机系统的自动化电子检测技术迫切需要应用到奶牛发情检测中。对奶牛的发情行为的影响因素、传统检测方法以及数字化的检测方法进行了阐述,并对其数字化检测趋势进行了系统深入的探讨。
Economic efficiency in milk production is influenced by feeding,good health of the herd,and high-reproduction results from dairy cows.Undetected or late detection of oestrus or of illness of animals has a negative impact on milk and fertility results as well as serviceable life of the herd.Commonly,oestrus detection is performed by visual observation,but this is particularly difficult on large dairy farms because of short observation periods during feeding and milking.As a result of technical progress in monitoring cows using computers,automatic oestrus detection has become possible.The influence factor,the detection methods and the future of the oestrus detection in dairy cows are discussed in this paper.
