Abstract: The present study was undertaken on “Effect of season and sex on birth weight and growth performance of Gangatiri Calves”on28birth weight records of Gangatiri calves obtained from SHUATS dairy farm Prayagraj, during the period from1st April, 2015 to 1st September 2017. Season of birth was divided in three seasons (summer, rainy and winter) as per three groups which were weight at birth, weights at 03 months age and weights at 6 months age. Sex on birth was divided into two groups male and female. It was concluded that the season had no – significant effects on weight at birth, weights at 03 months age and weights at 06 months age of Gangatiri calves, hence season has no role to play with regard to birth weight and growth performance. Sex had significant effect on birth weights, whereas weights at 03 months age and weights at 06 months age of Gangatiri calves registered no significance influence of sex of calves. It is clear that paternal birth weight is associated with the birth weight of male calves but not with female calves and therefore supports the notion that there is a genetic regulation along the male line.
