The comparison of artificial insemination success between unsexed and sexed sperm in Ongole Crossbred cattle

Abstract

Abstract The aim of this study was to compared the success of artificial insemination (AI) between unsexed compared to sexed sperm in Ongole Crossbred cattle. Both types of sperm were frozen semen and produced by Artificial Insemination Center Singosari Malang Indonesia. In this study, Percol Density Gradient Centrifugation was applied as protocol to select Y sperm (sexing). In total, 154 heads of female cattle divided equally into two groups namely unsexed and sexed sperm. All females were received double dosage of frozen semen during AI time. The parameters observed were percentage of Non Return Rate (NRR), Conception Rate (CR) and Pregnancy Rate (PR). The results showed that unsexed and sexed group values at NRR-1 were 90.91 and 77.92%, NRR-2 were 88.31 and 76.62%, CR were 79.22 and 57.14% and PR were 84.42 and 75.33%, respectively. According to the result, it is concluded that AI using unsexed sperm shows better result compared to the sexed.
