dc.description.abstractBody weight is the most economically important and easily measured trait of meat animals. The purpose of this study is to estimate genetic and non-genetic factors affecting the birth weight of goats. Birth weight data on 487 newborn goat kids of two genetic groups viz., non-descript (237) and Boer graded (250) goats were analysed by least-squares analysis using LSMLMW PC-2 program. The study revealed highly significant (P< 0•01) effect of sire and sex of kid on birth weight. The regression of birth weight on dams body weight was found to be highly significant (P<0.01). The overall average birth weight was 2.17 ± 0.03 Kg. The male kids (2.26 ± 0.04 Kg) were heavier than the female kids (2.09 ± 0.04 Kg). The kids born during the northeast monsoon were heavier than the kids born in other seasons. The Boer graded kids (2.22 ± 0.06 Kg) were heavier than the non-descript kids (2.13 ± 0.06 Kg) but the difference was non-significant, indicating the uniform managemental practices followed in the farm. The significantly high heritability (0.425 ± 0.156) of birth weight in goat indicates the better scope for improvement of birth weight through individual selection.en_US
