Temperature conditions were measured with an electric dynamic catathermometer (EDC) and thermometers in pig farrowing houses 13 and 90 cm above the floor of the central and side corridors, boxes for sows and in piglet pens, heated with electric infra-radiators (input 525 W). The heat flow density of the EDC sensor, characterizing the cooling properties of the environment, was higher near the floor, at the ends of stables, on the sides exposed to wind, and after turning on the fan. The thermal conditions in the farrowing houses were therefore highly variable. In the piglet pens the heat flow density was usually kept at a very low level, owing to the thermal radiation of the electric infra-radiators, with possible bad implications for production. However, these facts cannot be documented just by the current measurements of air temperature.
温度条件是使用电动动态冷却温度计（EDC）以及温度计在13号和9号产仔舍中进行测量的，测量位置在中央走廊和侧走廊地面上方13厘米和90厘米处、母猪栏以及仔猪栏，这些地方用电热辐射器（输入功率525瓦）供暖。EDC传感器的热流密度表征了环境的冷却特性，在靠近地面处、畜舍端部、迎风面以及开启风扇后，热流密度更高。因此，产仔舍中的热状况变化很大。在仔猪栏中，由于电热辐射器的热辐射，热流密度通常保持在非常低的水平，这可能对生产产生不利影响。然而，仅凭当前的气温测量无法记录这些情况。
