The objective of this work was to explore the possibilities of modelling the static and dynamic responses of total heat production of broiler chickens to step changes in temperature and light intensity (light-dark alterations) using compact dynamic model structures. 2. Seventy-seven experiments were performed in an open-circuit respiration chamber to measure the dynamic response of heat production to step variations in temperature and light (on/off). The animal responses were modelled using transfer function model structures. 3. It was demonstrated that the complex process of the dynamic response of heat production of broiler chickens to step changes in air temperature and light-dark alterations can be modelled assuming 1st order dynamics. The coefficient of determination between measured and simulated heat production was on average 0.83 for responses to air temperature and 0.93 for responses to light-dark alterations.

本研究的目的是利用紧凑的动态模型结构，探索对肉鸡总产热量对温度和光照强度的阶跃变化（明暗交替）的静态和动态响应进行建模的可能性。2. 在开路呼吸室中进行了77次实验，以测量产热量对温度和光照（开/关）阶跃变化的动态响应。使用传递函数模型结构对动物的响应进行建模。3. 结果表明，假设为一阶动力学，可以对肉鸡产热量对气温阶跃变化和明暗交替的动态响应这一复杂过程进行建模。实测和模拟产热量之间的决定系数，对气温响应平均为0.83，对明暗交替响应平均为0.93。
