| Abstract | Data on 920 buffaloes were analyzed for dry period and calving interval. The buffaloes comprised three genetic groups, viz., Graded Murrah, Diara buffaloes and non-descript buffaloes. Buffaloes were enumerated from 145 dairy units located in and around Patna Bihar. Genetic Groups had shown highly significant (p LT 0.01) influence on both the traits. The dry period varied as 130 (days) in Graded Murrah, 151 (days) in Diara buffalo and 150 (days) in non-descript ones. Farming system and location did not significantly influence these traits. Lactation order had highly significant effect on these traits. The dry period varied from157 days in first lactation to 140 days in fourth lactation while calving interval varied from 466 days in the first lactation to 441 days in the fourth lactation. |
