Ovarian responses to intramuscularly administered pregnant mare serum gonadotropin (PMSG) were measured in 23 mouflon ewes (Ovis musimon). Ovulation rates increased significantly with 1,000 i.u. PMSG or higher. PMSG at 1,200 i.u. also produced a significant increase in follicles !10 mm. Ova flushes showed recovery rates lower than for controls. Fertility rates were also lower, with zero fertility at 1,100 and 1,200 i.u. PMSG. Ten fertilized ova were transferred from mouflon to domestic sheep, re- sulting in 3 pregnancies, and 2 births. Pregnancies were established only with 16-32 cell ova and when estrous synchrony of donor and recipient was within 4 hours.
