Calves have been fed colostrum at birth will be randomly assigned two groups starting on day two after birth until weaning at 8 weeks old. Calves of the control group will be kept in individual pen and offered two times of milk replacer feeding daily as commonly done in current dairy farming. Calves of treatment group will be kept in group pen with automatic milk replacer feeding system and offered preset amount of milk replacer according to individual age. Data collection includes activity pattern, automatic milk replacer feeding record, weekly body weight, daily health monitoring (diarrhea and respiratory disease), weaning body weight and body weight changes two weeks after weaning.乳用仔牛飼養管理行為監測dairy calffeeding managementbehavior monitoring
