Effect of CIDR and PGF2α to Improve the Conception Rate in Repeat Breeding Buffaloes

The study was conducted to evaluate the effect of CIDR and PGF 2  to improve the conception rate in Repeat breeding buffaloes under field condition. The buffaloes were divided into group I (n = 32) and group II (n = 112). Group I animals were served as control and were inseminated during natural estrus and Group II animals were treated with an intra vaginal P4 device (CIDR) for 9 days and PGF2? was given intramuscularly 24 hrs prior to CIDR removal. Fixed time Artificial insemination was carried out at 48 and 72 hrs after CIDR removal. The overall conception rates obtained was 37.50% in group I animals and 79.46% in group II animals treated with CIDR and PGF 2 
