Abstract
The present study entitled "Augmenting reproductive efficiency of infertile buffaloes using controlled breeding techniques in tribal areas" was carried out in tribal areas of Dahod district of Gujarat on 16 postpartum anestrus, 15 repeat breeder and 7 normal cyclic buffaloes. The objectives were to evaluate clinical response and monitor peripheral plasma progesterone, biochemical and macro-micro minerals profile at different time intervals in anestrus (CIDR and Ovsynch protocol) and repeat breeding (AI+GnRH and Mid-cycle PGF2α inj.) buffaloes treated with different hormonal preparations. The effect of these protocols was evaluated by comparing estrus induction response, estrus induction interval and AI at estrus as well as pregnancy rates. Also the plasma progesterone profile was studied using RIA technique. Serum total cholesterol, total protein, calcium, inorganic phosphorus and magnesium by assay kits on autoanalyzer, and micro-minerals (Zn, Fe, Cu, Co, Mn) profiles using wet digested samples on atomic absorption spectrophotometer at different time intervals in all buffaloes and controls. Nine true anestrus buffaloes were inserted with intravaginal CIDR on day 0, upto day 7 and were given i/m Inj. of PGF2α 25 mg (Inj. Pragma, 2 ml) to all the buffaloes. FTAI was done on day 9 and Inj. GnRH, 10 μg (Inj. Gynarich, 2.5 ml) was given to all the buffaloes. All the 9 (100 %) buffaloes exhibited estruses within stipulated time. The inseminations were done at first, second, third estruses and overall conception rates found to be 33.33, 33.33, 25.00 and 66.66 per cent, respectively. The interval from PGF2α injection to induced estrus was 69.44±1.32 hrs (n=9) and the fertile estrus interval was 16.66±6.94 days (n=6) in treated buffaloes.
