The productivity of Bali cows at Livestock Breeding Centre of Excellence for Bali Cattle

(Timor-Leste), Master of Science in Animal Science (Gadjah Mada University)

Thesis Abstract:

This research aimed to identify the reproduction rate, pre-weaning growth rate, and factors affecting the productivity of Bali cows at the Livestock Breeding Centre of Excellence for Bali Cattle (BPTU) in 2010–2011. The research used 130 Bali cows and employed a survey method-based descriptive analytical research. Results showed that in terms of cow performance, the calf crop recorded 64.62 percent; mortality, 5.95 percent, calving interval, 11.36 ± 1.05 months; and parity, 3.51 ± 2.01 heads. In terms of the performance of pre-weaning growth, the birth weights of male and female calves were 18.37 ± 1.65 kg and 18.27 ± 1.20 kg, respectively. The weaning weights of male and female calves were 93.53 ± 21.00 kg and 87.66 ± 12.04 kg, respectively, with weaning time of 205 days. The average of pre-weaning daily weight gains were 0.37 ± 0.10 kg/head/day and 0.34 ± 0.06 kg/head/day for male and female calves, respectively. The reproduction rate and productivity rate of cows were 61.98 percent and 56.15 kg/cow/yr, respectively. Based on statistical analysis, it was concluded that the productivity rate of cows and pre-weaning growth rate among Bali cows at the BPTU Bali in 2010–2011 were moderately high. Such a moderately higher productivity rate was affected by the tight selection factor on cows based on performance test and progeny test.
