Abstract

This study evaluated the comparative efficacy of conventional and sexed semen in Achai cattle at Zam Zam Dairy Farm, Bannu during 2023-24. Sixty healthy Achai cows (1st-3rd parity) were equally divided into two groups - one inseminated with conventional Jersey semen and the other with sexed Jersey semen. Estrus detection was performed thrice daily, followed by artificial insemination using standard protocols. Pregnancy diagnosis through rectal palpation at 60-90 days post-insemination revealed significantly higher (p<0.05) conception rates with conventional semen (56.67%) compared to sexed semen (23.33%). While sexed semen produced 100% female calves, the substantially lower conception rate highlights important practical limitations for its use in lactating indigenous cattle under field conditions.
