Abstract:
To assess the efficacy of Doublesych, Estradoublesynch and Modified doublesynch protocols on estrus induction and conception rate in postpartum anestrus Graded Murrah buffaloes. A study was conducted with forty (40) Pluriparous Graded Murrah Buffaloes between 2-4 calvings exhibiting postpartum anestrus between 90-180 days were selected and were randomly divided into four groups (n=10). Group-I (Control group), Group-II (Doublesynch protocol), Group-III (Estradoublesynch protocol) and Group-IV (Modified doublesynch protocol). Results revealed, that the estrus response rate was significantly (p< 0.05) higher in Group II (90%) and Group III (90%) followed. The mean time taken for the onset of induced estrus from PGF2α was significantly (p< 0.01) shortest in Group-IV (59.63 ± 1.21 hr). However, the mean score for estrus intensity was significantly (p< 0.05) higher in Group-III (19.33 ± 1.87) followed by Group-II (17.44 ± 1.71). The mean duration of estrus was significantly (p< 0.05) higher in Group-III (20.67± 1.13 hrs). The overall conception rate was 20.00, 80.00, 70.00 and 60.00 per cent in Group-I, Group-II, Group-III and Group-IV respectively. The present investigation concluded that Doublesynch protocol could be used as best hormonal protocol to induce the estrus as well as improve the conception rate in postpartum anestrus Graded Murrah buffaloes.
