The present study was conducted to assess the effect of non-genetic factors on body weight of Sonadi sheep of different age. In this study data on 1396 Sonadi sheep maintained over the period of 2012-2019 under the Mega Sheep Seed Project, College of Veterinary and Animal Science, Navania, Vallabhnagar, Rajasthan were analysed to assess the effect of non-genetic factors (Year of birth, season of birth, sex, type of birth,) on body weight at birth, 3, 6, 9 and 12 months age . The overall least-squares mean along with standard error for of body weight were observed as 2.82±0.03, 10.06±0.27, 14.62±0.38, 17.41±0.43, 21.96±0.55 kg at birth, 3, 6, 9 and 12 months of age respectively. Year of birth had highly significant (p≤0.01) effect on all age. Effect of season of birth on body weight was also highly significant (p≤0.01) effect on all age. Sex of lamb showed s highly significant (p≤0.01) effect on all age whereas effect of type of lamb on body weight was found to be highly significant at birth, 3, 9 and significant at 6 and non-significant at 12 month of age.
