SHEEP: Oestrus induction and increased ovulation rates

CATTLE: Anoestrus

PIGS: Anoestrus
Injection of 500 to 1500i.u. Pregnecol to gilts or sows. Anoestrus during lactation: Injection of 1000 to 2000i.u. Pregnecol 10 or more days after farrowing followed 3 to 4 days later by injection of 500 to 1000i.u. hCG (Human Chorionic Gonadotrophin).

BITCH: Anoestrus
Injection of 100 to 500i.u. Pregnecol per kg bodyweight at 7-day intervals until oestrus occurs, followed by injection of 500 to 1000i.u. on day 4 of oestrus. Or daily injections of 20i.u. Pregnecol per kg bodyweight over 10 days followed by injection of 500 to 1000i.u. S.C. on day 10.
Anoestrus is often caused by inadequate management (feeding and housing), therefore optimum management is a prerequisite for effective treatment.
