Abstract

The present study was aimed to assess the impact of post-insemination human chorionic gonadotropin (hCG) administration on mid-luteal functions and conception rate in Murrah buffalo. The study was conducted on 2 buffalo treatment groups viz., estradiol + controlled internal drug releaser (CIDR) + gonadotropin releasing hormone (GnRH, n = 27) and ovsynch + CIDR (n = 22). Half of the animals in each group received intramuscular (i.m.) hCG (3000 IU, i.m.) on day 12 post-ovulation while groups served as control. The CG administration on day 12 post-ovulation improved corpus luteum size and progesterone level as well as first service conception rate after timed insemination in buffaloes.
