Abstract. Gunawan M, Kaiin EM. 2020. The success of artificial insemination with sperm sexing bali cattle in East Lombok, West Nusa Tenggara. Pros Sem Nas Masy Biodiv Indon 6: 571-575. Increasing population and genetic quality of Bali cattle with artificial insemination (AI) using frozen sperm from superior bulls at the Artificial Insemination Center (AIC) Lelede Banyumulek, West Nusa Tenggara Province is done through the transfer of sperm sexing technology in Techno Park Banyumulek. This study was conducted to determine the success of AI application with sexing sperm of Bali cattle in livestock farmer groups in East Lombok Regency. The treatment was carried out by conducting sexing sperm AI as many as 620 doses divided into two packs of straw, mini straw (0,25 ml) and medium straw (0,5 ml). Balinese cattle acceptors are used as many as 450 cows from the herd in Wanasaba District. The parameters of the success of AI with sexing sperm in medium straw packaging obtained a service per conception (S / C) value of 76% significantly different (P<0,05) higher and a conception rate (CR) value of 1,87 significantly differently (P<0,05) more-lower than the mini straw packaging. The match of the sex calves born from AI with sexing X sperm reached 77,8% of female calves.
