摘　　要：选用日龄相近、平均体重约18kg左右的杜长大生长猪128头,按照遗传背景相同、性别比例一致的原则随机分为2组,每组4个重复,每个重复16头猪。对照组饲喂玉米-豆粕基础饲粮,试验组在基础饲粮的基础上用3%的膨化羽毛粉替代6%的豆粕,其余用玉米补充。预试期3d,正式试验期为30d。饲养试验结果表明,在断奶仔猪饲粮中添加3%膨化羽毛粉替代豆粕对日增重、日采食量及料重比均没有显著影响(P>0.05)。A total of 128 DLY growth pigs with similar daily weight and average weight of about 18 kg were randomly divided into 2 groups according to the same genetic background and the same sex ratio. Each group contained 4 replicates and 16 pigs per replicate. The control group was fed with corn-soybean meal basic diet.The experimental group was fed with 3% expanded feather meal instead of 6% soybean meal on the basis of basic diet, and the rest was supplemented with corn. The pre-test period was 3 days and the formal test period was30 days. Feeding experiment showed that adding 3% expanded feather meal to the diet of weaned piglets instead of soybean meal had no significant effect on daily gain, feed intake and feed-to-weight ratio(P>0.05).
