Data on 4109 Chokla animals maintained at Central Sheep and Wool Research Institute (CSWRI), Avikanagar, Rajasthan were collected to assess the effect of non-genetic factors on preweaning growth performance. The least-squares means for body weight at birth and 3 months of ages and average daily gain during birth to 3 months of ages were 2.81±0.010 kg, 12.90±0.062 kg and 111.88±0.657 g/day, respectively. The least-squares analysis of variance revealed highly significant (P<0.01) effect of sex of lamb, period and season of birth on all the pre-weaning traits. The fixed effect of age of dam at lambing was highly significant on all the pre-weaning traits except on average daily gain from birth to 3 months of ages. Effect of dam’s weight at lambing had highly significant source of variation for all the pre-weaning traits. Thus, there is need of giving proper attention to the significant factors to achieve optimum productivity.
