Abstract

The efficacy of using progesterone releasing interavaginal device (PRID), PRID without estradiol benzoate, veramix sheep sponge and prostaglandin F2α in inducing and synchronizing estrus were evaluated in Naeimi ewes. All four treatments were successfully able to synchronize estrus. The interval to induce estrus was significantly (P<0.05) shorter and estrous intensity was significantly higher in PRID-treated group compared to other treatment groups. Serum progesterone values during subsequent estrous cycle and pregnancy rate were similar in all treatment groups. The results indicated that progestagens and prostaglandin F2α can effectively be used in management of reproduction in Naeimi sheep.
