Estrus synchronization and controlled breeding in goats using prostaglandin F(2)alpha.
Estrus synchronization in the goat employing the double injection regimen of 7.5 mg of prostaglandin F(2)alpha (Lutalyse) at each injection, resulted in 64% and 84% synchronization at first and second injections, respectively. Breeding at estrus induced by the second injection resulted in 90% conception. Kidding at the end of the gestation period was spread over a 17-day period. The first and the last does had 141 and 158 days of gestation, respectively. The findings of this study indicate that two injections of prostaglandin F(2)alpha 10 days apart is superior to a single injection for estrus synchronization in the goat. Breeding following the second injection resulted in high conception rate. Due to individual differences in gestational lengths, estrus synchronization with prostaglandin F(2)alpha cannot be depended upon for synchrony of kidding.
