Sweating rates and thermoregulation in male and feeale Bali cattle
I Wayan Kasa
Abstract
An experiment has been conducted to compare the sweating rate between male and female Bali cattle under tropical conditions in Bali, Indonesia with dry bulb (DB) temperatures varying from 25 to 34.5째C and relative humidity (RH) 70 to 98%. Rectal temperature (Tr) was significantly different (p < 0.05) between males and females (39.7 vs 39.4째C compared to 39.2 vs 38.8째C on weeks 1 and 8 respectively). There were significant effects on RR associated with both week 횞 sex (p < 0.01) and sex 횞 time (p < 0.01) interactions, with values for males higher than females. Skin temperature (Ts) differed significantly between sexes (p < 0.05), weeks (p < 0.05) and times (p < 0.01); being lower in females (36 vs 36.4째C). With prolonged working, there were marked increase in RR were recorded after 30 minutes (the overall increase was 12.4째C). Sweating rate (SR) differed significantly between sexes (p < 0.05), weeks (p < 0.01) and times (p < 0.01) during exercise. Females had a lower mean SR (225.3g/m2h) than males (238.8g/m2h). With increasing time, the highest SR was achieved after 30 minutes of exercise of 313.3g/m2h.
