The heat production for two breeds of laying hens was estimated by indirect respiration calorimetry. Using multiple linear regression techniques, egg energy output was identified as a significant contributor to variability in heat production (P = .0113). Heat production of the hens decreased with increasing egg energy output. Body weight, feed intake, egg energy output, and genetic stock were all significant contributors to variability in heat production. Comparisons of traditional techniques (relating energy balance to metabolizable energy intake) and multiple regression techniques (heat production as a function of body weight, feed intake, egg energy output, and genetic stock) for evaluating calorimetry data were made.
通过间接呼吸量热法估算了两个品种蛋鸡的产热量。运用多元线性回归技术，确定蛋的能量输出是产热变异性的一个重要影响因素（P = 0.0113）。母鸡的产热量随着蛋的能量输出增加而降低。体重、采食量、蛋的能量输出和遗传品系都是产热变异性的重要影响因素。对评估量热数据的传统技术（将能量平衡与可代谢能量摄入量相关联）和多元回归技术（产热作为体重、采食量、蛋的能量输出和遗传品系的函数）进行了比较。
