银鲈对六种饲料原料蛋白质和氨基酸的表观消化率

Apparent digestibility of protein and amino acid in six feed ingredients for Bidyanus Bidyanus

本试验用Cr2O3间接测定法测定了银鲈(BidyanusBidyanus)对秘鲁鱼粉、国产鱼粉、豆粕、酵母、麦麸、次粉等6种常用饲料蛋白质和氨基酸的表观消化率。结果表明,银鲈对这6种原料的蛋白质消化率和总氨基酸消化率分别为:86 20%和89 50%、82 53%和88 84%、76 96%和85 54%、72 93%和84 37%、61 23%和78 20%、68 06%和78 67%。

The apparent digestibilities of protein and amino acids in commom feed ingredients for Bidyanus Bidyanus were determined by the indirect method using Cr2O3 as a marker.The protein and amino acid digestibilities of Peru fish meal,China fish meal, soybean meal, yeast, wheat bran and middlings were 8620?% and 8950?%,8253?% and 8884?%,7696?%and 8554?%,7293?%and 8437?%,6123?% and 7820?%,6806?% and 7867?%,respectively.
