Penampilan reproduksi sapi Peranakan Ongole (PO) dan sapi Peranakan Limousin di Kecamatan Sawoo Kabupaten Ponorogo dan Kecamatan Tugu Kabupaten Trenggalek

Abstract

The purpose of this study was to evaluate artificial insemination program on the reproduction performance of Ongole crossbred and Limousin crossbred cattle. The materials of the study were Ongole crossbred and Limousin crossbred cattle. Descriptive analysis was used to determine service per conception (S/C), days open (DO), calving interval (CI), conception rate (CR) and calving rate (CvR). Meanwhile, t-test was used to analyse differences among those variables. The study showed that the value of S/C, DO and CI between Ongole crossbred and Limousin crossbreed cattle differed significantly (P<0.05). The average S/C, DO, CI of Ongole crossbred cattle were 1.3±0.32; 156.9±29.33 days; 430±43.72 days respectively. In addition, Ongole crossbred cattle had calving rate (CvR) as well as conception rate (CR) was 74%. Meanwhile Limousin crossbed cattle had 1.5±0.39 of S/C; 172.9±19.21 days of DO; 451.3±19.61 days of CI. Moreover, calving rate (CvR) and conception rate (CR) of Limousin crossbed cattle was 52%. The study concluded that reproduction performances of Ongole crossbred cattle were better than that of Limousin crossbred cattle. Keywords : days open, service per conception, calving interval, cattle
