Estrous, ovulation and reproductive responses of ewes synchronized with a long interval prostaglandin-based protocol for timed AI.

The aim was to characterize and assess the reproductive performance of a long interval prostaglandin (PG)-based protocol for timed AI (TAI) at different times. During breeding season three experiments were done involving 622 Merino ewes, 11 rams, and five androgenized wethers per 100 ewes. All ewes were estrus synchronized with two PG injections 15-day apart (PG15): Day -15 and 0 (Hour 0).
