dc.description.abstractThis study was carried out in villages of Amul as well as Panchamrut milk shed areas of Gujarat on 80 repeat breeding animals comprising 40 each cows and buffaloes, and 10 each normal cyclic cows and buffaloes (exhibiting oestrus within 90 days postpartum). The objectives were to evaluate and compare the therapeutic efficacy of various hormonal approaches, viz., Ovsynch protocol, Mid cycle PGFaa, AI+hCG inj. and Progesterone inj. 5th day post-AI, and to monitor the influence of these therapies on plasma progesterone, biochemical and minerals profiles on different days of treatment in cows and buffaloes. Ten repeat breeding cows and buffaloes each with average body condition score (BCS) of 2.75 to 3.50, without visible and palpable genital abnormalities were treated initially once with SC injection of ivermection 100 mg, IM injection of 3.0 g enrofloxacin to check invisible genital infection, IM injection of inorganic phosphorus and multivitamins AD3E. Owners of the animals were supplied with multimineral bolus for PC use, one bolus on alternate day for four times. In Ovsynch protocol ten each repeat breeding cows and buffaloes were administered with IM inj. of Buserelin acetate 10 µg on day 0, inj. Cloprostenol 500 µg on day 7, and second inj. of Buserelin acetate 10 µg was given IM on day 9, followed by FTAI twice 0 and 24 hrs later. The conception rates obtained in cows at induced estrus, second estrus, third estrus and overall were 50.00 (5/10), 20.00 (1/5), 25.00 (1/4) and 70.00 (7/10) per cent, respectively. The corresponding values in buffaloes were 40.00 (4/10), 33.33 (2/6), 0.00 (0/4) and 60.00 (6/10). The mean intervals from PGFα injection to induced estrus in Ovsynch treated cows and buffaloes were 81.17±0.63 and 78.73±1.10 hrs, respectively, with cent per cent estrus response.en_US
