Data on birth weight pertaining to 373 Mehsana kids for a period spread over 7 year (from 2011 to 2017) maintained at organised farm were utilized to study the various factors affecting it. On the basis of date of birth of kids, data were divided in to 3 different seasons and 7 periods (year). Effects of sex of kids as well as type of birth on birth weight were also assessed using least squares analysis. The average birth weight of Mehsana kids was 2.555 ± 0.043 kg. The male (n=180) Mehsana kids showed significantly (P<0.01) higher birth weight than female (n=193). This may be due to the effect of male sex hormone, which influences grow faster during pre-natal development. The birth weight of Mehsana kids born as single (n=263) 2.689 ± 0.042 kg were significantly heavier than those born as twins (n=110) 2.4107 ± 0.064 kg which is obvious because in multiple births the nutrients available from the mother are shared by twin kids. The effects of season on birth weight of Mehsana kids were estimated to be non-significant. The year of birth also had significant (P<0.01) effect on birth weight.
