PERFORMANS REPRODUKSI INDUK SAPI LOKAL PERANAKAN ONGOLE YANG DIKAWINKAN DENGAN TEKNIK INSEMINASI BUATAN DI KECAMATAN TOMPASO BARAT KABUPATEN MINAHASA

Abstract

REPRODUCTION PERFORMANCE OF ONGOLE CROSSBRED COWS MATED BY THE ARTIFICIAL INSEMINATION TECHNIQUE AT WEST TOMPASO DISTRICT, MINAHASA REGENCY. Artificial Insemination (AI) was the first generation in biotechnology of animal reproduction in Indonesia. Nowdays, Indonesian government still rely on AI to increase genetic quality and animal productivity especially for beef cattle and dairy cattle. The success of AI related with reproduction performance was determined by variabels of conception rate (C/R), service per conception (S/C) and calving interval (CI). West Tompaso District in Minahasa Regency had applied AI as government program since 2013. However, the scientific information about the success of AI in that location has not been well documented. The aim of this study was to evaluate the success of AI on acceptor’s reproduction performance aspect. Total AI acceptor samples used in this study were 63 head of Ongole crossbred cows. Research was conducted using study case involving primary and secondary data sources. Collecting data was done by interviewing the farmers picked by purposive sampling method. Variables observed included C/R, S/C and CI analyzed by decriptive-qualitative data analysis. The result showed that C/R was 55,56%, S/C was 1,44 and CI was 359,6 days. Therefore, it can be concluded that the reproduction of Ongole crossbred cows as AI acceptors was categorized into good performance.
