Hormonal control of fertility in sheep. 5. Use of rams in natural mating on ewes synchronized with FGA and PMSG



Hormonal control of fertility in sheep. 5. Use of rams in natural mating on ewes synchronized with FGA and PMSG



Annali della Facolta di Agraria, Universita di Bari80 1983; 31: 175-184



120 Altamura females at the end of lactation (around 150 days post partum) were given vaginal sponges containing 30 mg FGA for 14 days followed by 400 IU PMSG. They were then put with rams for 7 days at a ratio of 1 male :6 or 10 females , beginning immediately or 48 h after PMSG injection. The ram:ewe ratio had no significant effect on reproductive performance.
