Gonadotrophin-induced ovulation in melengestrol acetate treated female goat.

Adult, Black Bengal goats synchronized to oestrus with Melengestrol Acetate (MGA) could be subjected to superovulation with 1000 IU of the Pregnant Mare Serum Gonadotrophin (PMSG). However, with 500 IU of PMSG higher rate of ovulation observed only in goats above one year age was not significant. Results indicate that the successful superovulation in MGA synchronized goats depend both on the dosage of the PMSG, as well as upon the age of the treated animal.
