Plasma FSH, LH, the positive feedback of oestrogen, ovulation and luteal function in the ewe given bromocriptine to suppress prolactin during seasonal anoestrus

Abstract: Summary. The It is concluded that treatment with bromocriptine alone is unlikely to restore oestrous cycles to ewes in seasonal anoestrus.

“…Whether prolactin is related to cyclic activity has been quite controversial, and although most investigations have not found a clear relationship [43,46], the timing of prolactin secretion manipulation may be crucial for an effect on reproductive activity. Indeed, when prolactin was suppressed towards the end of the estrous season, the season was found to be extended [6], whereas suppression of prolactin during the anestrous period did not affect the timing of onset of cyclic activity [19,33].…”

“…A common approach to this question has been to use pharmacological sup pression of plasma PRL by treatment with the dopamine ago nist bromocriptine. In several such studies there has been no effect of treatment on pulsatile LH secretion [28,29] or oestrous cyclicity [7,30]. However, as well as inhibiting PRL secretion, dopamine D?…”
