Studies of adaptive traits of Bali cattle in Buleleng district, Bali and Barru district, South Sulawesi

Abstract

Abstract. Bali cattle have high adaptability, so the distribution area is spread across Indonesia. These studies aimed to determine the effect of environmental factors on physiology performance of Bali cattle in Buleleng district and Barru district. Skin and rectal temperature and respiration rate within a minute were measured in cattle across 5-days. Ambient temperature, relative humidity, wind speed, and light intensity were measured as environmental factors. Our findings suggest that environmental factors between the two districts were different (p<0.05), but the temperature and wind speed were not. In Buleleng, the relative humidity was 82.6 ± 14.4% and light intensity was 123.03 ± 24.83 kW/m 2 , whereas in Barru the relative humidity was 75.4 ± 12.6% and light intensity was 200.96 ± 25.11 kW/m 2 . Although both regions had different environmental conditions, the respiration rate of cattle was different between the two districts (p<0.05). Cattle respiration rate in Buleleng was 26-34 BPM, whereas in Barru it was 22-28 BPM. Our results indicate that the changes in environmental conditions affect changes in the cattle physiology profile in each district. Thus, Bali cattle have adaptability towards a variety of environmental conditions.

Effect of Heat Stress on the Physiological and Hematological Profiles of Horned and Polled Bali Cattle

“…The rectal temperature of polled Bali cattle increased more than that of horned Bali cattle during the day. Rectal temperatures in both Bali cattle are not very different from those reported byAritonang et al (2017a), who researched in the same district (Barru Regency) and reported that Bali cattle have rectal temperatures in the range of 37.6-38.6 o C. Putra et al (2021) also reported that the rectal temperature of Bali cattle increased from 37.5±0.3 o C in the morning to 38.7±0.2 o C in the afternoon. Contrary to Prahesti et al (…”
