Intravaginal hCG administration increases pregnancy rate in artificially inseminated cyclic dairy goats subjected to estrous synchronization.

Pregnancy establishing after artificial insemination (AI) in goats depends on many important aspects, including time of AI, ovulation and premature luteal regression. The knowledge of ovulation in relation to estrus onset, ovulation induction and strategies to prevent PLR can be valuable tools to increase pregnancy rate. This study tested the effect of hCG administration on pregnancy rate in artificially inseminated dairy cyclic goats after estrus synchronization Results of this study showed that hCG administration associated to AI significantly increased pregnancy rates in goats after estrus synchronization with dcloprostenol, which can be a valuable and promising tool to be applied in field conditions.
