【摘要】 以不同比例的鱼粉、豆粕为蛋白源 ,配以小麦粉、淀粉、鱼油、混合无机盐与混合维生素等 ,配制成蛋白质含量为 43%,鱼粉与豆粕的比例为 1 :0 0 0～ 1 :1 79的 6组配合饲料 ,并以小杂鱼为对照组饲料 ,喂养花鲈 (Lateolabraxjaponicus)。结果表明 ,花鲈的生长和消化率随着配合饲料中豆粕含量的增加而递减 ,但用豆粕鱼粉替代的比例在 40 %以下时并无显著差异。花鲈幼鱼适用配合饲料中鱼粉含量不应低于 40 %,鱼粉与豆粕的适宜比例为 1 :0 72～ 1 :1 1 5。更多还原

【Abstract】 Effect of partially replacing fishmeal by soybean meal on growth, digestibility, food utilization of sea perch \%Lateolabrasx japonicus\% juveniles was studied in a laboratory. Six test diets contained 43% crude protein with an animal vegetable protein ratio of 1:0-1:1 79 In controls, the animals were fed chopped trash fish Results indicated that growth, digestibility, food utilization were reduced with increase in animal vegetable protein ratio The optimal proportion of fish meal and soybean meal in formulated feed of \%Lateolabrax japonicus\% was 1:0 72-1:1 15更多还原
