Removing the calf after bonding may induce acute stress in the dairy cow. The responses of 8 Holstein-Friesian cows were examined immediately after the removal of their calves on the third day after parturition. Blood samples were taken before and after the separation for cortisol analysis. After separation, cows vocalized initially and moved to the feeding rack but started feeding shortly after that. Heart rate effects were restricted to the first 2 minutes after separation. Cortisol effects were not found. It is concluded that multiparous dairy cows respond only mildly immediately after their calves have been removed.
