摘　　要：本试验利用开放式呼吸测热装置在 2个环境温度 ( 1 3℃、2 3℃ )及定量采食 ( 2× 35g/kg0 .75· d)条件下对哈白猪 ( 2 1± 1 kg)的代谢产热量进行测定。试验结果表明环境温度对产热量有显著影响 ,1 3℃、2 3℃的产热量分别为 35 .7k J/kg0 .75·h和 2 6.3k J/kg0 .75·h。This experiment determined Habai swine's metabolic heat production with body weight of 21±1 kg, feed intake of 2×35 g/(kg 0.75 ·d) under two different environmental temperatures (13℃,23℃) by opening respiratory calorimetry system It was concluded from the results that environmental temperature effected significantly metabolic heat production, and heat production of 13℃, 23℃ was 5 7 kJ/(kg 0.75 ·h) and 26 3 kJ/(kg 0.75 ·h) respectively.\;
