Abstract:
Ovulation synchronization is an irresistible tool to augment fertility, but, efficacy of various protocols has not been reported in buffaloes. Twenty numbers of graded Murrah buffaloes were selected for the study and divided into two equal groups (I and II). The group I buffaloes were treated with Ovsynch protocol and group II buffaloes were treated with Ovsynch treatment plus CIDR protocol (Additional to Ovsynch protocol, CIDR was inserted intra-vaginally for 7 days from day 0 of Ovsynch and removed on the day of PGF2 on day 7. The buffaloes returned to estrus following TAI were inseminated artificially in the subsequent estrus. The interval to onset of induced estrus following ovulation synchronization in group I and group II buffaloes were 46.80 ±1.19 and 42.10±2.39 hours, respectively. The duration of induced estrus in groups I buffaloes differed significantly from group II buffaloes. The percentage of buffaloes with intense, intermediate and weak estrus 0 (0), 5 (50.00) and 5 (50.00) in group I and 2 (20.00), 7 (70.00) and 1 (10.00) in group II. The ovulatory response in group I and II buffaloes were 90.00 and 100.00 per cent, respectively. The conception rate after first and second insemination and overall conception rate in this study were 30.00, 20.00 and 50.00 per cent in group I buffaloes and 30.00, 40.00 and 70.00 per cent in group II buffaloes. The progesterone concentration in group I and group II buffaloes did not differ significantly, however, the progesterone concentration differed significantly within the groups. The serum estrogen concentration in group I and group II buffaloes did not differ significantly, however, the estrogen concentration differed significantly on the day of AI from other days of the treatment within the groups. The study concluded that the Ovsynch with CIDR protocol following mineral supplementation resulted in better conception than the Ovsynch group.
