Abstract

This study aimed to determine the success of artificial insemination (AI) using unsexed and sexed frozen semen with albumin sedimentation. This research was conducted from August to December 2022 at a farmer community in Pandesari Village, Pujon District, Malang Regency. The material used in this study was 78 heads of Friesian Holstein cattle, with the criteria of having a minimum body condition score of 2.5 (scale of 1–5), having normal reproductive organs, and showing signs of estrus. 38 cows were used as acceptors in artificial insemination (AI) with unsexed frozen semen, and 38 cows in AI with albumin sedimentation frozen semen. The variables used are non-return rate 1, non-return rate 2, and conception rate. The data obtained were then analyzed descriptively. The results showed that the percentage values of NRR1, NRR2, and CR in AI using frozen semen unsexed were 76.3%, 63.1%, and 47.3%, respectively, while the percentage values of NRR1, NRR2, and CR in AI using frozen semen sexed were 94.7%, 86.15%, and 63.15%. Based on the study's results, insemination success using albumin sedimentation frozen semen sexed showed better results than AI using unsexed semen.
