Effects of High Environmental Temperature on the Body Temperature of Thai Indigenous, Thai Indigenous Crossbred and Broiler Chickens

W. Aengwanich
The effects of high environmental temperatures on the body temperature of Thai Indigenous Chickens (TIC), Thai Indigenous Chickens Crossbred (TICC) and Broilers (BC) were determined for the purpose of comparing the chickens` responses to the increased heat. One kilogram of representative males and females of each of the three breeds were maintained at the environmental temperatures of 26 ±2 and 38 ±2 °C. Body temperature was investigated on days 1, 7, 14, 21 and 28 of the experimental period. The results revealed the following information: The body temperature of the chickens maintained at 38 ±2 °C was significantly higher than that of the chickens at 26 ±2 °C (p<0.05) and the body temperature of the BC maintained at 38±2 °C was significantly higher than that of the TIC and TICC (p<0.05). At 38 ±2 °C, on days 1, 7, 14, 21 and 28 of experimental period, the body temperature of the BC was significantly higher than that of the TICC and TIC, respectively (p<0.05). This experiment showed that the high environmental temperature had a greater effect on the BC than on the TICC and TIC, respectively.
