摘　　要：以瓦氏黄颡鱼(Pelteoebagrus vachelli)肌肉氨基酸组成为参考模式,研究了羽毛肽粉作为其饲料蛋白源的氨基酸营养价值,并与常规水产饲料蛋白源鱼粉进行了比较。结果表明,羽毛肽粉富含Ile、Leu、Phe+Tyr、Thr、Val,其特有的氨基酸组成特点决定了其在瓦氏黄颡鱼饲料中有一定的应用前景。作为蛋白源,在一定程度上弥补了鱼粉Phe+Tyr等氨基酸的不足,其主要限制性氨基酸为Lys、His、Met、Cys、Cys、Trp、Thr。在配方设计时应选用富含Lys的蚕豆粉浆蛋白粉,富含Thr、Trp的血粉,富含His的豆粕、玉米粉等蛋白源与其进行配合使用。The experiment was undertaken to estimate the amino acid nutrition of feather peptide meal and fish meal as feed protein resource for yellow catfish（Pelteoebagrus vachelli）. Feather peptide meal were rich in Ile,Leu,Phe＋Tyr,Thr,Val,indicated that it could be used as protein resource with fish meal, which was poor in Phe ＋Tyr. As protein resource for yellow catfish feed, the first restrict amino acid of feather peptide meal was Lys,followed by His, Met＋Cys, Trp, Thr. The balance of amino acid for feather meal can be improved by mixed with other protein resource such as, blood meal, soybean and so on.
