本试验按照“70 %基础饲料 +30 %被测原料”的饲料配制方法 ,用三氧化二铬指标物 ,测定了翘嘴红鱼种 (体重 12 5± 1 5 g )对鱼粉、血粉、蚕蛹粉、酵母、豆粕、花生粕、菜籽粕、棉籽粕等 8种常用的饲料原料的干物质、蛋白质、粗脂肪的表观消化率。结果表明 :翘嘴红对 8种原料的干物质表观消化率和蛋白质表观消化率分别为 4 3 4 3%～ 86 90 %和 6 6 34%～ 95 18% ,对 5种原料的脂肪表观消化率为 6 6 6 9%～ 94 16 %。
According to the preparation method of “70% basal diet + 30% raw materials for testing”, the test was conducted to test the effects of different concentrations of dietary chromium oxide (125 ± 15 g) Silkworm pupa powder, yeast, soybean meal, peanut meal, rapeseed meal, cottonseed meal and other eight kinds of commonly used feed ingredients dry matter, protein, crude fat apparent digestibility. The results showed that the apparent digestibility of dry matter and apparent digestibility of protein were 8% to 86% and 36% to 36%, respectively, for eight kinds of raw materials, Apparent digestibility of fat 6 6 6 9% ~ 94 16%.
