中文摘要:
      本文研究了日本沼虾(Macrobrachium nipponense)饲料的最适蛋白质含量、脂肪含量及能量蛋白比。试验用饲料由酪蛋白、糊精、混合油、复合维生素和无机盐混合物等组成。本试验用的日本沼虾体重为 1.77±0.23克,试验期间水温为 21—25℃。用增重率、饲料系数和肝胰脏α-淀粉酶活力等作为评价指标。试验结果表明:日本沼虾配合饲料适宜蛋白质含量为 36.8—42.27%,适宜脂肪含量为6—12%。当配合饲料的蛋内质含量在适宜范围内,饲料能量蛋白比(C/P)为8千卡/克蛋白左右,每公斤配合饲料的总能量为3006—3561千卡是最为适宜的。当饲料总能量在一定范围内,随着饲料碳水化合物含量的增加,肝胰脏α-淀粉酶活力增强。
英文摘要:
      The appropriate protein content, fat content and calorie-protein ratio in the diet for the freshwater shrimp have been studied. The experimental diets were composed of casein, dextrin, mixed.oils, mixed vitamins and. minerals.The shrimp used in the experiment were 1.77 ±0.23 gRams in weight, and reared at the water temperature of 21 and 25℃. Talking the weight gain, food conversion and α--amylase activities of liver-pancreas as evaluation indexes, the results of the experiment indicate that 36.8--42.27% protein content, 6-12% fat content about 8 Kcal/per gram protein calorie-protein ratio (C/P) and 3006-3561 Kcal/Kg in the formulated diet seems suitable. When the total calorie of the formulated diet is given a certain range, the a-amylase activities of liver-pancreas are enhanced with the increase of carbohydrate content in the diet.
