哺乳仔猪暖床的制作与使用效果试验

设计制作了四种仔猪暖床并进行性能测定,选出两种性能较好者,在生产条件下进行使用效果的对比试验。结果显示:加热器功率为150W暖床优于100W者,尤其是150W调温控温暖床——升温速度较快,达预定温度时间短,温度可随仔猪需要调节,耗电量少。与150W控温型暖床相比,仔猪平均日增重在1～7日龄阶段提高20.01%,差异显著(P<0.05);其他阶段差异不显著;仔猪发病率和死亡率分别降低16.6个和10个百分点。经济效益比较高。

The Experiment of Making and Using The Warm-Beds For Piglets

Two better types of warm-bed for piglets have been chosen from four different types and we have experimented with the two types under production conditions. The result shows that by comparison, the temperature inside the 150W regulative controllable warm-bed can be raised fast, reaching the established temperature in a very short time, and that the temperature can be regulated to meet pigs' needs with less power consumption. As compared with the 150W controllable warm-bed, the average daily gain of 1~7 day-old piglets in the 150W regulative controllable warm-bed is 20.01% higher than that in the 150W controllable warm-bed (p<0.05), and the incidence of a disease has dropped 16.6 percentage points, the death rate has dropped 10 percentage points. So it really has improved economic performance.
