Abstract
The present study was conducted to know the effect of CIDR and it’s combinations with
prostaglandin F2a (PGF2a) and gonadotrophin releasing hormone (GnRH) in postpartum anestrous
buffaloes in terms of estrus signs, estrus induction rate and pregnancy rate. Thirty two healthy
Graded Murrah buffaloes were selected after clinical, gynaecological and ultrasonographic
examination and divided in to 4 groups comprising of 8 animals in each group viz. Group 1 (Control,
not received any treatment), Group 2 (CIDR inserted intravaginally for 10 days), Group 3 (CIDR
insert for 10 days plus 500 μg cloprostenol i/m on 9th day) and Group 4 (CIDR insert for 10 days,
500 μg cloprostenol i/m on 9th day and 10 μg of Busereline 24 hours after CIDR removal). The
animals detected in estrus were bred through AI. The group 4 buffaloes exhibited estrus in 67.10
± 12.5 hrs after CIDR removal with higher estrus induction (87.5%) and pregnancy rate (87.5%)
than other groups.
