Performance of female Bali cattle in different management systems at Field Station of Sekolah Peternakan Rakyat (SL-SPR) Kuamang Abadi

Abstract

Abstract This study aims to evaluate the performance of Bali cows in different management systems in the Field Station of Sekolah Peternakan Rakyat (SL-SPR) Kuamang Abadi. The linear body measurement and reproductive performances of one hundred twenty-six Bali cows owned by 64 farmers located in 4 villages in SL-SPR Kuamang Abadi were measured and recorded. Survey and observation were done from October to November 2020. Data were analyzed using statistical and descriptive methods. The parameters of linear body measurement included chest circle (CC), body length (BL), and body height (BH). The reproductive performance included age first calving (AFC), calving interval (CI), days open (DO), and service per conception (S/C). The result of linear body measurement showed that the largest CC was in a semi-intensive system at 158,03 cm; the largest BL and BH in the intensive system were 119,35 cm and 111,2 cm, respectively. The result of the reproductive performance showed that cattle in the semi-intensive systems had lower averages AFC, CI, DO, and S/C, i.e., 958,7 days, 375,1 days, 90,1 days, and 1,7, respectively. The results obtained can be used as the basis for improving maintenance management and the development of breeding Bali cattle in SL-SPR Kuamang Abadi.
