Data recorded on 10,148 Black Bengal kids maintained at farmer’s herds in different districts of West Bengal from 2008 to 2019 were used to study the effect of non-genetic factors on body weight from birth to 12 months of age. The data were analysed using least squares technique. The effect of year of kidding on body weight of Black Bengal kids at different ages was significant (p<0.05). Influence of season and parity of the dam had significant effect (p<0.05) on body weight of kids from birth to 6 months of age. Sex of the kid significantly influenced body weight from birth to 12 months of age. Effect of types of birth on body weight at different ages up to 12 months of age of Black Bengal kids were significant (p<0.05). Significantly higher body weight at birth was recorded in single born kid, followed by twin, triplets and so on.
