Abstract

A trial was conducted to study the effect of CIDR on conception rate (CR) in repeat breeding (RB) Vrindavani cows following insemination with liquid semen. After insemination with liquid semen, the experimental RB cows were divided into two groups: group-I (n=13) was treated with CIDR between day 5 and 18 post-insemination, while group-II (n=12) was kept as negative control. Pregnancy diagnosis was done on day 60 post-insemination by per rectal palpation. Conception rate (%) in CIDR treated group was 5/13 (38.46%), whereas, it was 2/12 (16.67%) in the control group. Though the increase of CR by 21.79% in the CIDR treated group was statistically non-significant as compared to the control.
