Calves were removed for 48 hours from cows at 2 localities in 1978. Removal shortened the interval from calving to first oestrus at both localities. It shortened the interval from calving to conception and advanced the 1979 calving date at the locality which had the better level of nutrition. Weaning weights of the removed calves were depressed at both localities. The intervals from calving to first oestrus were affected at both localities by dam age and breed, 1978 calving date and condition score at removal.
