仔猪保温箱的改良与应用效果研究

为探讨研制更为有效合理的仔猪保温装置，降低养猪成本，提高养猪效益，本试验对普通仔猪保温箱进行了改良，即采用了PTC材料进行供热，并采取了热风循环式（G1）及直接供热式（G2）与我场原用红外灯和电热板供热作对照，对比其应用效果。结果表明：改良组二种供热方式均能提高仔猪成活率，降低仔猪发病率，提高断奶窝重，节约能耗，而且以G1的综合效益为最佳，第二组G2次之。试验表明PTC热风循环式仔猪保温箱值得推广使用。

Study on Improvement and Application Effect of Piglet Incubator

To explore the development of more effective and reasonable piglet insulation devices, reducing the cost of feeding to improve effective,the test was conducted to improve the general piglet incubator, and using the PTC material for heating, taking a hot air circulation （G1） and direct heating （G2） field with my original heating with an infrared lamp and electric hot plate as a control, compared with its application results. The results showed that the improved two kinds of heating methods could improve the survival rate of piglets, reduce the disease incidence of piglets, improve the total litter weaning weight, and saving energy consumption. Comprehensive benefits of the （G1） was the best, the second group （G2） followed. Therefore,the PTC hot air circulating piglet incubator is worth spreading.
