Keberhasilan inseminasi buatan menggunakan semen sexing beku pada Sapi Persilangan Ongole

Abstract

<p>The Artificial Insemination (AI)  results in Beef cattle are expected to be male calf because they can increaseweight gain rapidly, so in this study AI was carried out by using sexing semen with Percoll density gradient centrifugation method containing Y sperm.This study was conducted to evaluate the success rate of AI using frozen sexing semen on Ongole Cross Breed. The study method used wasexperimental, comparing AI frozen sexing semen and frozen semen in 54 Ongole Cross Breed. The study variableswere Non Return Rate₁ (NRR₁), Non Return Rate₂ (NRR₂) and Conception Rate (CR).The study showed that the success rate of based on the value of NRR₁ and NRR₂AI using frozen sexing semen on Ongole Cross Breed is lower than un sexed frozen semen with the NRR₁ value is 73,91%; 93,54% while the value of NRR₂ was 69,56%; 83,87%. Based on CR value of frozen sexing semen higher than un sexed frozen semen showed CR valuewas 43,47%; 35,48%.</p>
