| Abstract | ||||
| This study was carried out on 60 normal cycling Saanen goats to investigate the occurrence of estrus following treatment with PGF2 and subsequent fertility. The animls were assigned into two groups (30 each). The animals were injected with 8 mg of PGF2 and saline in treated and control groups respectively. The injection was repeated after 11 days later. The incidence of estrus and the time interval from the last injection to the appearance of estrus signs was reported. The bucks were used to help in the detection of the hidden estrus signs and for breeding the does. Pregnancy diagnosis was done at day 50 post breeding using ultrasonic scanning. The parturient does, type of birth, gestation length and time of placental drop were estimated. The results revealed that, all the treated does came to heat within 48 hours after the last injection with PGF2, 80% of them proved to be p < /strong>regnant. All the pregnant does kidded normally. Three does gave single kid, 18 gave twin kids and the remainder (9) kidded triplet kids. The average gestation length in treated does was 148.4 days. The p < /strong>lacenta was exp < /strong>elled within 180 minutes from exp < /strong>ulsion of the last kid. Low percentage of estrus, pregnancy and kiddding does were observed in control animals. Finally, it could be suggested that the use of PFG2 during the breeding season was effective in estrus synchronization without any adverse effect on the fertility. | ||||
