Abstract
Successful oestrous synchronization protocol must support a reasonable level of pregnancy in the synchronized cycle. Premature luteal regression and a drop in progesterone, the pregnancy hormone and concentration is a common phenomenon in goats following oestrus synchronization. Therefore, this study was undertaken to evaluate the comparative efficacy of two oestrus synchronization protocols on the progesterone profile of the Malabari cross bred goats which would be of practical significance for estrous synchronization of goats. It was observed in this study that the progesterone profile in goats did not vary with the treatment regimens to which they were subjected. Curiously, we observed that the progesterone concentrations on the day of insemination showed significant difference (P<0.05) between the goats those conceived and those failed to conceive. We could make the earliest detection of pregnancy using progesterone estimation by ELISA by day 17th post insemination, while it could be confirmed only on day 20th by ultra-sonography.
