Reproductive Performance of Ongole Crossbred Cattle in Deli Serdang Regency as Affected by Body Condition Score

Abstract

Reproductive efficiency is a key determinant of productivity in beef cattle, and Reproductive performance is significantly influenced by the Body Condition Score (BCS). The purpose of this study was to assess the reproductive performance of Ongole Crossbred (PO) cattle based on the relationship between BCS, Service per Conception (S/C), and Calving Interval (CI) in Deli Serdang Regency, North Sumatra. The research was conducted from July to August 2022 using a descriptive method. Purposive sampling was used to pick 377 PO cows, and information was gathered through farmer interviews and direct observation. and secondary data from local livestock institutions. BCS was assessed using the Scottish/Canadian scoring system, while S/C and C/I were obtained from insemination records. According to the findings, PO cattle had an average BCS of 2.65±0.18, indicating thin to moderate body condition. The mean S/C value was 2.16±0.25, suggesting that more than two to become pregnant, insemination attempts were necessary.. The average CI was 429.8±15.4 days, exceeding the ideal 12-month interval. Regression analysis revealed a negative relationship between BCS and both S/C and CI, indicating that better body condition improved reproductive outcomes. In conclusion, BCS has a major impact on the reproductive success of PO cattle in Deli Serdang, and improvements in nutritional and reproductive management are required to enhance cattle productivity.
