CORRELATION OF REARING SYSTEMS AND BEEF CATTLE PROFILES ON THE PERFORMANCE OF BEEF CATTLE IN TANJUNG JATI SUB-DISTRICT

Abstract

Abstract:  This study aims to determine the relationship between Body Condition Score (BCS) and Service Per Conception (S/C) and Calving Interval (CI) for PO Crossing Cattle in Tanjung Jati Village. The sample used was 44 female Ongole crossbreed (PO) cows. The method used in this research is a case study, data collection is done primary and secondary. The variables observed are Body Condition Score (BCS), Service Per Conception (S/C) and Calving Interval (CI). The results of this study indicate the regression equation. The relationship between Body Condition Score (BCS) (X) and Service Per Conception (S/C) (Y) has a regression equation Y = 2.300-0.041X. This means that by increasing the Body Condition Score (BCS) by 1 point, the Service Per Conception (S/C) value will decrease by 0.041%. The coefficient of determination (R2) is 50.9%, meaning that this value indicates that the Body Condition Score (BCS) contributes 50.9% to the value of Service Per Conception (S/C). The relationship between Body Condition Score (BCS) (X) and Caliving Interval (CI) (Y) has a regression equation Y = 1.955-0.041X, which means that for every additional Body Condition Score (BCS) of 1 point, the Calving Interval (CI) will decrease by 55.6%, with a coefficient of determination (R2) of 55.6% meaning that the Body Condition Score (BCS) contributes 55.6% to the Calving Interval (CI) while the remaining 44.4% comes from other factors.

Keywords: Ongole crossbreed cattle, Body Condition Score (BCS), Service Per Conception (S/C) and Calving Interval (CI).
