摘　　要：[目的]为血粉制品在鲤鱼饲料配方中的应用提供依据。[方法]以0.5%Cr2O3为外源指示剂,按"85%基础饲料+15%试验原料"组成饲料,测定鲤鱼对鱼粉、膨化血粉、血球蛋白粉、普通血粉4种动物性蛋白原料干物质、粗蛋白及氨基酸的表观消化率。[结果]鲤鱼对膨化血粉的干物质表观消化率最高,其次为血球蛋白粉、鱼粉,普通血粉最低。鲤鱼对血球蛋白粉的蛋白质表观消化率最高,其次为膨化血粉、鱼粉,普通血粉最低。除胱氨酸外,鲤鱼对血球蛋白粉的氨基酸表观消化率均高于膨化血粉,而鲤鱼对膨化血粉的各种氨基酸表观消化率均高于鱼粉和普通血粉。[结论]鲤鱼对4种动物性蛋白原料的表观消化率由大到小依次为:血球蛋白粉>膨化血粉>鱼粉>普通血粉。[Objective] The aim was to provide the basis for the application of blood meal products in the feed formula of Cyprinus carpio.[Method] With 0.5% Cr2O3 as the exogenous indicator,according to the formula feed of 85% basic feed＋15% tested material,the apparent digestibility of C.carpio to dry material,crude protein and amino acid in 4 animal protein raw materials of fish meal,expanding blood meal,spray-dried blood cells and common blood meal were detected.[Result] The apparent digestibility of C.carpio to dry material of the expanding blood meal was highest,followed by spray-dried blood cells and fish meal,and that of the common blood meal was lowest.The apparent digestibility of C.carpio to protein of spray-dried blood cells was highest,followed by expanding blood meal and fish meal,and that of the common blood meal was lowest.Expect cystine,the apparent digestibility of C.carpio to the amino acid of spray-dried blood cells were all higher than that of expanding blood meal,but the apparent digestibility of C.carpio to each amino acid of expanding blood meal were all higher than that of fish meal and common blood meal.[Conclusion] The order of the apparent digestibility of C.carpio to 4 animal protein raw materials was spray-dried blood cells〉expanding blood meal〉fish meal〉common blood meal.
