Data on growth traits of 7151 animals used in present study were collected from the history sheets of Rambouillet sheep maintained at Government Sheep Breeding Farm, Zaban, Reasi, J&K, India, over a period of 16 years (2000-2015). Body weight traits were birth weight (BW), three month body weight (3MW), six-month body weight (6MW), nine-month body weight (9MW) and yearling weight (YW). The data were classified to study the major effect of non-genetic factors like period of lambing, season of lambing, sex of lamb and type of birth. Based on these classifications, the significant effects were adjusted for performance traits. | Effects of non-genetic factors on body weight traits in Rambouillet sheep
