The objective of study to compare the conception rate in repeat breeder dairy cows after using injection of GnRH (Ovulanta)@ 20 μg intramuscularly on 5th day of artificial insemination (AI). Non-infectious cows were randomly divided into two groups Group I (no treatment) and Group II (GnRH on 5th day of post AI). At the time of AI, mean serum glucose concentration recorded 58 and 61 mg/dl in Group I and II. All the cows were screened for pregnancy diagnosis on day 45. The pregnancy percentage observed in Group I and Group II were 10 and 20 % respectively. From the study we concluded that the GnRH on 5th day of post AI was not enhancing the reproductive performance up to the mark in field condition.
