摘要/Abstract

摘要： 试验探讨了不同配比饲料对革胡子鲶胃肠消化酶活性的影响。用含蛋白量为28%、33%和38%的人工配合饲料分别与鲜杂饲料（鸡肠）按1:6、1:5和1:4分别混合为A、B和C组三种饲料,D组为鸡肠饲料。在室内养殖条件下,分别用上述4种饲料对起始体重为（32.70±1.39）g的1龄革胡子鲶养殖51 d后测定其胃肠中的蛋白酶、淀粉酶和脂肪酶活性。结果表明,投喂混有人工配合饲料的革胡子鲶胃肠蛋白酶活性随饲料中蛋白含量的增加而增加,其中C、D组酶活性显著高于A、B组;各组中胃肠淀粉酶活性总体偏低,但A、B、C三组胃、前肠淀粉酶活性均显著高于D组;各组脂肪酶活性变化无明显规律。

Abstract: This experiment was conducted to study the effects of different ratios of feeds on the activities of gastrointestinal digestive enzymes of Clarias Lazera. The protein percentage of artificial feeds of 28%, 33% and 38% was mixed with the fresh mixed feed (chicken intestine) to A, B and C group of three kinds of feed with the ratio of 1:6, 1:5 and 1:4, respectively, and the group D is the chicken intestine feed. One year old Clarias Lazera (initial average weight（32.70±1.39）g) were fed for 51 days in laboratory, and then the activities of the gastrointestinal protease, lipase and amylase were mesured. The results show that the activities of the gastrointestinal protease of Clarias Lazera which were fed with mixed artificial diets increased with the protein level increase in feed, and the activities in the group C and D were higher than those of the group A and B significantly. The amylase activities of all groups in Clarias Lazera were low, but the activities of A, B and C groups in stomach and foregut were higher than those of the D group. The lipase activities of each group had no obvious regularity.
