Conception rate of artificial insemination using sexed frozen semen with albumin sedimentation method on Friesian Holstein cow

Abstract

This study aimed to determine the success of Artificial Insemination (AI) using unsexed and sexed semen of albumin sedimentation method based on Non-Return Rate, Conception Rate, reproduction performance, estrus characters, and feed nutrition. This research was conducted from August to December 2022 in Bendosari Village, Pujon District, Malang Regency. The material used in this study was 76 Friesian Holstein (PFH) cows with the criteria of having a minimum Body Score Condition (BCS) of 2.5 (scale of 1-5), normal reproductive organs and showing signs of heat. Thirty-eight cows were inseminated with unsexed frozen semen and 38 with albumin sedimentation sexed semen. The results showed that the percentage value of CR in AI using unsexed frozen semen was 55.23%, while CR in AI using albumin sedimentation sexed was 60.53%. In conclusion, AI's success using frozen albumin sedimentation sexed semen shows better results than AI using unsexed frozen semen.
