| 摘 要： | 本试验旨在研究补饲对20～45日龄仔貂生长性能的影响。选择2，4窝20日龄仔貂作为试验动物，随机分为2组，每组12窝。对照组仔貂随母貂哺乳采食，不补饲；试验组仔貂除随母貂哺乳采食外，每天额外补饲2次。试验期25d，2组仔貂均在45日龄断奶分窝。结果表明，试验组仔公貂40日龄和45日龄的体重极显著高于对照组（P〈0．01）。试验组35日龄仔公貂体重以及35日龄、40日龄和45日龄仔母貂的体重均显著高于对照组（P〈0.05）。由此得出，补饲可以显著增加20～45日龄仔貂的生长性能。

| Abstract: | The objective of this trial was to study the effects of supplementary feeding on body weight of kits aged from 20 - 45 days. Twenty four litters of twenty - day - old kits were randomly assigned to 2 groups with 12 htters in each group. Kits in the control group were only sucked with female minks,and kits in the experimental group were additionally supplemented with feed twice a day. Both groups were weaned at 45 - day - old and the experiment lasted for 25 days. The results showed that, supplementary feeding significantly increased the body weight of male kits when they were 40 and 45 days old（ P 〈 0.01）.The body weight of 35- day- old male kits and 35,40,4.5 days old female kits supplemented with feed were observably higher than that of the control group（ P 〈 0.05）. In conclusion, supplementary feeding could improve growth performance of kits aged from 20 - 45 days. |
