THE SUCCESS RATE OF ARTIFICIAL INSEMINATION USING SEXING LIQUID SEMEN WITH DIFFERENT METHODS IN BALI HEIFER

Artificial Insemination (AI) in this study uses the results of sexing liquid semen, which aims to get the calf following the objective of the breeding institution that is producing Bali cows. The study was conducted at Balai Pembibitan Ternak Unggul and Hijauan Pakan Ternak located in Pangyangan, Pulukan Sub district, Jembrana Regency, Bali. The study was conducted on July 7, 2019 until November 7, 2019. The research material was 45 Bali heifers. Bali heifer was synchronized using Enzaprost@, after showing signs of estrus, double doses artificial insemination at 2 hours after estrus and 8 hours after estrus. The Bali heifer was inseminated with non-sexing and sexing liquid semen using andromed diluent, P0 = non-sexing liquid semen, P1 = liquid semen by the Percoll Density Gradient Centrifugation (PDGC) method in the lower layer and P2 = liquid semen by the Egg White Gradient Sedimentation (EWS) method in the upper layer. Pregnancy evaluation is calculated based on Non-Return Rate (NRR) and Conception Rate (CR). The results showed Non-Return Rate (NRR) P0, P1 and P2 = 86.67%, 60% and 53.33%. While the Conception Rate (CR) at P0, P1 and P2 is 53.33%, 13.33% and 26.67%.
