仔猪采暖保温设备的研究 Ⅱ.初生仔猪红外线采暖设备的比较

study on heating and heat preserving equipment for new born piglets Ⅱ. Comparison between fhe infrared heaters for new born piglets

本试验比较了石英管灯、红外线灯辐照下的辐射热、空气温度、动物模型产热量与散热量以及10、20、30、60日龄仔猪体重。结果悬挂高度为40和50cm时,二者辐照下的气温无显著差异,在高度为50cm时,辐射热量差异也不显著,但40cm时,石英管灯的辐射热量大于红外线灯的。二者辐照下的动物模型产热量与散热量均无显若差异。动物试验表明,仔猪各日龄体重二种灯间差异不显著。石英管灯可代替红外线灯作为仔猪的采暖设备。

The following indexes in the fields irradiated by the guantz tube infrared lamp (QTIL) and infrared lamp ( IL ) were compared : irradiance, air tempesature, heat roduetionand heat loss of model animal, and body weights of piglets of10、20、30and60 dags of age. The difference of air temperatures was nonsignificant when either heater (QTIL、or IL)was 49 or 50 cmabove th floor, and so was the difference of irradiance when either heater was 50 em above. But The amount of irradiance of Q TIL was more than of that of IL when in was 40em above. There were nonsignificant difference of the heat produetionand heat loss of model animal. The result of the experiment wifh QTIL and IL carried out in the farrowing house showed that the difference of the body we-ights of piglets of various days of age was nonsignificant. The QTIL can be used as heater for new born piglets in place of IL.
