Abstract

Data were collected on 1341 Sahiwal progenies born from 2007 to 2012 and maintained by 1239 farmers across twenty-two districts in Jharkhand for average lactation yield was found to be 5.85 lts/day which was compared with the yield of Non-Descript and Sahiwal cattle and the heterosis (hybrid vigour) was found in the F1 generation w.r.t. milk yield and it was found to be 51.15% by mid parent method and -3.09% by better parent heterosis. Further, the paired t-test found that although the cross-bred F1 generation was non-significantly superior to Desi cattle at P-value of 0.05, F1 hybrid is significantly superior (better) than the desi at P-value of 0.02. The result is very important keeping in view the fact that the breed improvement programme of non-descript cattle is highly advocated to increase the milk production of low producing non-descript cattle in Jharkhand.
