【摘要】 对淇河鲫鱼与普通鲫鱼的蛋白酶、脂肪酶和淀粉酶活性进行比较分析,结果表明:两种鲫鱼肠道中的蛋白酶活性显著高于肝胰脏的(P<0.05),而且肠道中的蛋白酶活性顺序是前肠<中肠<后肠;肝胰脏和肠道各部分的脂肪酶活性没有显著差异;肠道中的淀粉酶活性显著高于肝胰脏的(P<0.05),但是淇河鲫鱼前肠中的淀粉酶活性与中肠的没有显著差异,而后肠淀粉酶活性达到最高(P<0.01);淇河鲫鱼的蛋白酶、脂肪酶和淀粉酶活性比普通鲫鱼的高。更多还原

【Abstract】 The results of studies on the activities of protease,lipase and amylase in Qi-river crucian carp and common carp showed that the activities of protease in the intestine were higher than those in the hepatopancreas(P<0.05).The order of protease activities in the intestine was foregut<midgut<hindgut.There were no significant differences in the lipase activities in any part of the intestine and the hepatopancreas.The amylase activities in the intestine were higher than those in the hepatopancreas(P<0.05),but the amylase activities in foregut and midgut had no significant difference and that in hindgut is the highest in Qi-river crucian carp(P<0.01).The activities of the three digestive enzymes in Qi-river crucian carp were higher than those of common carp.更多还原
