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.
