Sensible and latent heat (moisture) production data were obtained for broiler chickens grown from 3 to 7 weeks of age on litter at three environmental temperatures: 15.6, 21.1, and 26.7 C. Shape of the specific sensible and latent heat curves were similar for the 15.6 and 21.1 C temperatures, but the sensible heat production at 15.6 C was about 12% greater than for 21.1 C for chickens weighing between 500 and 1000 g; the different increased for heavier chickens. Heat production curves for 26.7 C were markedly different from the other two temperatures. Specific sensible heat at 26.7 C was 2.8 cal/hr (g) and was independent of body weight over the range 500 to 1800 g. The data were compared to those published since 1969 to determine if increased growth rates have affected heat production data. Results indicate no discernible effect for cool temperatures, but for warm temperatures it appears that increased growth rates may be accompanied by an approximately proportional increase in specific sensible heat production.
获取了在三种环境温度（15.6、21.1和26.7摄氏度）下，于垫料上饲养的3至7周龄肉鸡的显热和潜热（水分）产生数据。15.6摄氏度和21.1摄氏度时，比显热和潜热曲线的形状相似，但对于体重在500至1000克之间的鸡，15.6摄氏度时的显热产生量比21.1摄氏度时约高12%；体重较重的鸡差异更大。26.7摄氏度时的产热曲线与其他两个温度明显不同。26.7摄氏度时的比显热为2.8卡/小时（克），在500至1800克范围内与体重无关。将这些数据与1969年以来发表的数据进行比较，以确定生长速率的提高是否影响了产热数据。结果表明，低温时没有明显影响，但对于温暖温度，生长速率的提高可能伴随着比显热产生量大致成比例的增加。
