Treatment of postpartum cows with an oestrogen preparation (Folliculin) shortened uterine involution and increased CR at the 1st postpartum oestrus. THe use of Folliculin + PGF2 alpha during the 1st month post partum reduced the service period by 16 days, compared with untreated cows. The use of PGF2 alpha in heifers and in cows with a long open interval after calving resulted in CRs to 1st insemination of 36.0-83.3% in heifers and 34.4-66.6% in cows.
