| Abstract | ||||
| Estrus was synchronized in Saanen goats by using vaginal sponge during breeding and non breeding season. Two experiments were conducted (60 treated and 30 non treated goats in each exp < /strong>eriments). In the breeeding season, the goats were injected with 400 or 500 IU PMS, which was carried out at the day of sponge removal. While outside the breeding season, the doses of PMS were 700 or 600 IU and the injection was 2 days before sponge removal. The goats exhibiting cyclicity were allowed to be serviced by fertile bucks. The pregnant does were detected at day 50 post service by using the scanning technique. The total numbers of parturient does" and type of birth were recorded. The results of the present investigation indicated that all the treated goats exhibited cyclicity during the breeding and non-breeding season. The treated goats gave a higher percentage of pregnancy and kidding rates during breeding season than outside the breeding one. The animals that were injected with low doses of PMS gave a high percentage of pregnancy and kidding rates during the breeding and outside the breeding season, a high incidence of twins and triplets was recorded between the goats that were injected with low doses of PMS. | ||||
