abstract
A study was undertaken in the Lohaghat block of Champawat district, Uttarakhand to assess the conception rate and sorting efficiency of sexed semen under field condition. Artificial Inseminated (AI) was done in 218 animals during the study period. Cows were divided in two groups G1 and G2 on the basis of use of sexed and unsexed semen, respectively for AI. In G1, total 70 cows inseminated with sexed semen from three centers of Lohaghat block and conception rate, female calves and male calves were 40%, 82.14% and 17.85%, respectively. Total 148 cows were inseminated with unsexed semen from the same three centers. The observed conception rate, female calves and male calves were 49.32%, 50.68% and 49.31%, respectively. Female calves and male calves% were significantly (P<0.01) higher and lower respectively with sexed compared to unsexed semen. The present study highlights the importance of using sexed semen under field condition to increase the milk yield and reduce the burden of male calves on the farmers.
