The use of heating systems for new-born piglets can prevent major losses in the first 5 weeks of life. The present study had the objective of evaluating three heating systems in creeps for new-born piglets, being: floor-heated floor with circulating water (HF), incandescent lamp type SPOT 40 W (L) and incandescent lamp type SPOT 40 W plus black metal plate (LP). The variables evaluated were piglet performance (total weight gain and mortality), bioclimatic data (temperature and relative air humidity), animal behaviour and economic revenue. Bioclimatic data were recorded in the external environment, in the maternity and in the interior of each shelter/creep for 21 days, three times a day, as well as the capture of photographic images for analysis of the animals’ disposal. The mean temperature of the retractors, the weight at weaning and the weight gain were higher in the HF treatment. Treatment HF improved the percentage of dispersed animals and provided the best thermal environment and the highest revenue at the time of the commercialization of the piglets.

新生猪不同加热系统的评价

对新生仔猪使用加热系统可以防止在生命的前 5 周出现重大损失。本研究的目的是评估新生仔猪的三种加热系统，它们是：带循环水 (HF) 的地暖地板、SPOT 40 W (L) 型白炽灯和 SPOT 40 W 加黑型白炽灯金属板 (LP)。评估的变量包括仔猪生产性能（总增重和死亡率）、生物气候数据（温度和相对空气湿度）、动物行为和经济收入。生物气候数据在外部环境、产妇和每个庇护所/爬行的内部记录了 21 天，每天 3 次，并捕获摄影图像以分析动物的处置情况。牵开器的平均温度，断奶时的体重和体重增加在 HF 治疗中更高。HF 处理提高了分散动物的百分比，并在仔猪商品化时提供了最佳的热环境和最高的收入。
