Sex-sorted sperm is now widely used in cattle breeding to enhance industrial competitiveness and achieve high female fertility. We bought a "Whole-mom" from the Nuri Science Co., Ltd company. The objective of this study was to evaluate the pregnancy rates and calves sexing proportion of male and female calves produced using Artificial insemination (AI), both performed using sexed and conventional sperm. The study was carried out spring to autumn season on 150 Hanwoo bred on a farm. In all superovulated donors, inseminations were initiated 12 hours after the onset of standing estrus. In a experiment, to take a sexed semen was mixed with "Whole mom" and conventional semen in a water bath at 37℃ for 20 minutes. The sexed and nonsexed semen was deposited in the body of the uterus. After collection, embryo morphology was assessed under a stereomicroscope. Embryos were transferred to the uterine horn ipsilateral to the CL. The conception rates were 73.3% (45/33) sexed semen and 48.8% (90/44) conventional semen. The sex ratio for sexed-semen inseminations was 70% (21/30) females for singleton births within a 279.2 to 282.1 day gestation interval. The sex ratio for unsorted semen was 56.8% (25/44) females for births. The use of X-sorted sperm, already widely employed for AI in dairy cattle has the potential to alter the structure of the industry by increasing the replacement heifer supply, creating opportunities for using a proportion of the dairy herd for producing beef animals, and improving the rate of genetic selection.
