Abstract :This study was designed to determine the effects of semen type and calf gender on milk yield parameters, milk electrical conductivity and milk flow values and postpartum maternal body weight. A total of 265 Holstein cows in the first lactation were used in the study. The effect of sperm type on maternal body weight levels after calving and milk electrical conductivity values was significant insert ignore into journalissuearticles values(P0.05);. Heifers inseminated with sexed semen had higher 100-days milk yield, milk peak yield and postpartum maternal body weight in the first lactation. Milk peak duration was higher in heifers inseminated with conventional semen insert ignore into journalissuearticles values(P0.05);. In conclusion, heifers inseminated with sexed semen had higher maternal body weights, 100-days milk yield, milk peak yields and milk electrical conductivity levels in the first lactation than inseminated with conventional semen
