A study was carried out under field conditions on 50 acyclic/anestrus buffaloes to evaluate the efficacy of four standard estrussynchronization protocols, viz., Doublesynch, Estradoublesynch,Ovsynch, and Ovsynch Plus (10 buffaloes in each protocol, andin untreated control group) in terms of estrus induction response,conception rates at induced estrus with FTAI and monitoringplasma progesterone, protein and cholesterol profile at differenttime intervals during treatment and day 12 post-AI. All the animalsreceived pre-synchronization treatment, i.e., Inj. 100 mg ivermectins/c, Inj. tono-vita 20 ml, and multi-minerals 1 bolus daily for 7days. The conception rates obtained at induced estrus (FTAI)were 50.0, 40.0, 30.0 and 50.0 % with Doublesynch,Estradoublesynch, Ovsynch and Ovsynch Plus protocol,respectively. The rests were taken as non-conceived ones. Theplasma progesterone concentrations monitored on day 0 (startof treatment), 7/9 (PGF2α injection), 10/12 (FTAI) and on day 12post-AI revealed significant (p Lass Than 0.01) effect of sampling days inall four protocols with higher values on day of PGF2α injectionand on day 12 post-AI compared to other days. Moreover, theplasma progesterone concentrations were significantly (p Lass Than 0.05)higher in conceiving than the non-conceiving buffaloes on day12 post-AI in all 4 protocols. The mean plasma protein andcholesterol profile did not differ significantly between days in anyof the protocols. The animals under Doublesynch protocol howeverhad significantly higher protein values as compared to Ovsynchand Ovsynch Plus protocols. Moreover, the non-conceivingbuffaloes under Ovsynch Plus protocol had significantly (p Lass Than 0.05)lower mean plasma protein (5.73±0.15 vs. 6.49±0.13 g/dl) andcholesterol (57.42±1.19 vs. 76.68±1.85 mg/dl) concentrationscompared to their counterparts. It was concluded that all fourhormonal protocols improved plasma progesterone profile andconception rates in acyclic buffaloes without altering plasmaprotein and cholesterol profile. The maximal benefit was withDoublesynch and Ovsynch plus protocols, hence these can bepracticed under field conditions to manage acyclic buffaloes.
