摘要：

Removing the calf after bonding may induce acute stress in the dairy cow. We examined the responses of dairy cows immediately after the removal of their calves, Eight dairy cows were successively separated from their calves on the third day post-partum and heart rate and behaviour of the cows were recorded. In addition, the cows were blood sampled before and after the separation for cortisol analysis. After separation, cows vocalised initially and moved to the feeding rack but started feeding shortly after that. Heart rate effects were restricted to the first minutes after separation and cortisol effects were not found. We conclude that multiparous dairy cows respond only mildly immediately after their calves have been removed, Feasible explanations for the observed mild response are discussed.
