摘　　要：试验旨在利用棉籽粕、玉米干酒糟及其可溶物(DDGS)来替代饲料中部分豆粕,通过对肉鸡生产性能和代谢率的研究,选择合适的优质蛋白质饲料替代品并降低饲养经济成本。试验结果表明,在同等营养水平条件下,用棉籽粕或DDGS来代替饲料中部分豆粕,对肉鸡的增重、采食量以及饲料转化率的影响差异不显著(P>0.05)。利用DDGS和棉籽粕代替部分豆粕在降低养殖成本的基础上不会降低肉仔鸡的生产性能。This experiment is aimed at cottonseed meal and distillers dried grains with soluble（DDGS） to re- place some the soybean meal of the forage, by researching the broiler＇s production performance and metabolic rate, provides theoretical basis for choosing high quality protein feed substitutes and reducing the feeding cost. The result showed that under the same nutrition condition, replacing soybean meal with cottonseed meal or DDGS wasn＇t a sig- nificant difference（P〉0.05） on broiler＇s weight, food intake and feed conversion rate. In concluse, it was feasible to replacing soybean meal with cottonseed meal and DDGS on broiler＇s diet. Not only it would not reducing the produc- tion performance of broiler, but also can reduce the production cost.
