title: Ovulation rate in induced oestrous cycles of anoestrous ewes given bromocriptine.
abstract: The suppression of prolactin in anoestrous ewes by daily injections of bromocriptine reduced the average number of corpora lutea on Day 8 after induced oestrus from 2.8 to 1.6 (P less than 0.02). There was a significant correlation (r = 0.87, P less than 0.05) between the preovulatory peak values for prolactin and ovulation rate in treated but not in control ewes. Bromocriptine failed to prevent the ewes from returning to anoestrus after the induced oestrus.
