Different oestrous synchronizing protocols like CIDR-controlled internal drug-releasing, Ovsynch and Co-synch are used for enhancing the reproductive efficiency of buffaloes but the conception rates are variable. A total of 32 true anoestrous buffalo were selected for the study and were divided into four groups (T1, T2, T3 and T4) each group comprising eight anoestrous buffaloes. T1 group was kept as control. The blood plasma progesterone (P4) was estimated on day ‘0’ (just before treatment), day 7 (at the time of PGF2 alpha administration), day 9 and day 21 post-AI. The overall higher conception rate of 62.5% was observed in the CIDR protocol followed by Ovsynch and Co synch. The mean progesterone level was significantly (p<0.05) higher in CIDR protocol on day 21 post-AI and on day 7 followed by days 0 and 9.
