选用20kg左右的DLY生长猪64头,随机分为4个处理,每个处理4个重复,每个重复4头,分别饲喂基础日粮、添加2%、4%、6%水解羽毛粉（等蛋白替代豆粕）的日粮。结果表明,随着试验日粮中水解羽毛粉添加量的提高,试验猪的日采食量和日增重降低,而料肉比上升,并且6%处理组差异达到显著（P〈0.05）;各处理组的干物质表观消化率、蛋白质表观消化率和有机物表观消化率均差异不显著（P〉0.05）,而氮的表观生物学价值和净蛋白利用率随着水解羽毛粉添加量的提高明显降低,并且6%处理组的净蛋白利用率显著低于对照组（P〈0.05）和2%处理组（P〈0.05）;2%处理组的单位增重饲料成本较对照组降低0.20元/kg。

64 DLY （DurocxLandrancexYorkshire） growing pigs with BW 20 kg were randomly divided into 4 groups, and 4 replicates in each group with 4 pigs in each replicate. The control group was fed the basal diet, and group I to group 111 were added hydrolyzed feather meal with 2%, 4% and 6% to substitute soybean meal. The result indicated that with the increasing hydrolyzed feather meal,tlie AFI and ADG decreased gradually, and F/G increased gradually. There were no significant difference on the apparent digestibilities of. DM, CP and organics among four groups, and there was significant difference of NPU among the control group, the 2% and 6% groups （P〈0.05）.The feed cost for ADG of 2% group was lower than that of control group.
