ABSTRACTThree different estrous synchronization protocols were evaluated. Treatment includedan injection of prostaglandin (PGF2α;1 ml VSM - Vulva-sub mucosal route) on palpation ofCL; status of the estrous cycle was evaluated by rectal palpation and addition ofgonadotropin releasing hormone (GnRH 2.5ml), fixed time insemination (FTAI) was done 72h post PGF2α injection. Similar was the second protocol in which, in gonadotropin releasinghormone (GnRH; 2.5 ml.) 7 days addition to PGF2α ; 1 ml VSM administration and 9 daysGnRH; 2.5 ml was administered 48 h post PGF2α ; 1 ml VSM injection and FTAI was done.For the third protocol, GnRH treated buffaloes were observed for 7 days and then PGF2α; 14days injection and GnRH;16 days was administered and at the time of A.I. Three differentgroups of animals were maintained for three different protocols respectively. Statistical dataanalysis (using chi-square) showed that first and second protocol have been foundsignificantly (P<0.05) better than third protocol used in field buffaloes of Rajasthan.Key words : Estrus, Synchronization, GnRH, PGF2α, Buffaloes, Reproduction.1Farm Manager,
