TINGKAT KEBERHASILAN INSEMINASI BUATAN (IB) PADA SAPI POTONG DI KECAMATAN TANJUNG PALAS KABUPATEN BULUNGAN

This study aims to determine the success rate of Artificial Insemination (AI) in Limousin, Simmental, and Bali cattle breeds in Tanjung Palas District, Bulungan Regency. The study used productive female cattle and cows that had given birth once, originating from three cattle breeds: Limousin, Simmental, and Bali. Each breed included a sample of 50 cows for the years 2022 and 2023. The research method used was a survey with direct field observations using purposive sampling. The female cattle included were those that served as AI acceptors in Tanjung Palas District, verified through the AI recording cards owned by the farmers. Data were collected from both farmers and AI officers. The variables observed included Service Per Conception (S/C), Conception Rate (CR), and Calving Rate. The data obtained were analyzed using the chi-square test (χ2). The results of the study showed that the Artificial Insemination Program in Tanjung Palas District has not been running optimally. This was evident from the Conception Rate in cattle in 2022–2023: Simmental cattle 22%–16%, Limousin cattle 18%–16%, and Bali cattle 16%–24%, with an overall rate of 56%–54% for 2022–2023.The S/C values for cattle in 2022–2023 were as follows: Simmental cattle 2.02–2.24, Limousin cattle 2.26–2.4, and Bali cattle 2.12–2.1. The Calving Rate for cattle in 2022–2023 was as follows: Simmental cattle 94%–96%, Limousin cattle 88%–94%, and Bali cattle 96%–94%. The chi-square analysis (χ2) conducted on the Conception Rate and Calving Rate in Tanjung Palas District in 2022 and 2023 for Simmental, Limousin, and Bali cattle showed no significant difference (P > 0.05).
