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24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。%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 litters 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 ,45 days old female kits supple-mented 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 .
