摘　　要：选用1日龄樱桃谷肉鸭200只，随机分为两组，1个试验组，1个对照组，每组2个重复，每个重复50只。对照组1～6周自由采食，试验组1～3周自由采食，4～6周采用限制饲养（限量）。试验结果表明：6周龄时，试验组的饲料转化率比对照组提高了12．9％，差异显著（P＜0．05），但日增重降低了9．13％，差异不显著（P＞0．05）；腹脂率降低34．2％，差异极显著（P＜0．01）；皮脂率降低15．1％，差异显著（P＜0．05）；瘦肉率提高了11．9％，差异不显著（P＞0．05）。：We have chosen 80 cherry Beef ducks of 1 day life，and they were separated averagely and randimly to 2 groups．The ducks of contrast group were feeded freely in the first 3 weeks，then feeded limitedly between 4th week and 6th week．The results have shown that the food conversion－ratios of the test group are 12．9 per cent higher than that of contrast group with marked difference（P＜0．05＝．The vate of abdomen－fat is 34．2 per cent lower than that of contrast group，and there is eytremely marked difference（P＜0．05）．The rate of fat under the skin is 15．1 per cent lower than contrast group with marked difference（P＜0．05）．The rate of loan meat of test group is 11．9 per cent higher than that of contrast group without marked difference（P＞0．05）
