中华鳖幼鳖对4种饲料原料中粗蛋白质和氨基酸的表观消化率
Apparent Digestibility of Crude Protein and Amino Acids of Four Feed Ingredients for Juvenile Soft-Shelled Turtle (Trionyx sinensis)
摘要
Abstract
The apparent digestibility of crude protein and amino acids of 4 feed ingredients—silkworm chrysa-lis, fermented soybean meal, meat-bone meal and corn gluten meal for juvenile soft-shelled turtle ( Trionyx sinensis) were determined in this experiment, in order to explore the new type protein feed ingredients for soft-shelled turtle. Four experimental diets were formulated. The experimental diets were consisted of 70% basal diet and 30% test feed ingredient, and contained 0.5% chromic oxide as an exogenous indicator. One hundred and fifty juvenile soft-shelled turtle with the average body weight of (120.0±1.5) g were randomly divided into 5 groups with 3 replicates per group and 10 soft-shelled turtle per replicate. The soft-shelled turtle in basal diet group were fed the basal diet, and those in the other 4 groups were fed one of experimental diets, respectively. After 1 weeks feeding, the fecal samples were collected by siphon method, and then the apparent digestibility of crude protein and amino acids was determined. The results showed as follows:1) the apparent digestibility of crude protein in corn gluten meal, fermented soybean meal and silkworm chrysalis for soft-shelled turtle was 90.57%, 86.34% and 85.75%, respectively, higher than that in meat-bone meal (75.98%) (P<0.05). 2) For animal protein sources, the apparent digestibility of total amino acids in silkworm chrysalis was higher, which was 92. 44%, while that in meat-bone meal was lower, which only was 75. 39%. For plant protein sources, the apparent digestibility of total amino acids in corn gluten meal was higher, which was 96.56%, and that in fermented soybean meal was 87.90%. The results indicate that silkworm chrysalis can be used as a source of high quality animal protein source, and fermented soybean meal can be used as a better plant protein source for soft-shelled turtle.关键词
