摘要

A study was undertaken in 105 flocks in the breeding tract (Buxar, Bhojpur and Rohtas districts of Bihar) of Shahabadi sheep to analyse the effect of non-genetic factors (location, flock size, season, sex, , and type of birth, ) on birth weight. The overall least squares mean of birth weight in Shahabadi lambs was 2.34±0.03 kg. All the non-genetic factors except flock size had significant (P<0.01) effect on birth weight. Lambs reared at Buxar and Bihiya blocks of Buxar district, winter season, malelambs and lambs born as single, registered higher birth weights. The findings of the study could be useful to breeders for considering these factors which had significant effect on the birth weight during the selection of animals for future breeding programme.
