【摘要】 选取相同生长阶段、体重均匀的异育银鲫160尾,随机分为5个组,每个组16尾,每个组设2个重复。糖萜素的添加水平为0、0.5、0.9、1.2和1.5 g/kg。结果表明:在适宜的温度范围内,试验2组异育银鲫的蛋白酶、淀粉酶和脂肪酶活力最高,其次是试验1组和试验3组,对照组最低。蛋白酶适宜温度为40~50℃,淀粉酶适宜温度为30~40℃,脂肪酶适宜温度为30~40℃。糖萜素对异育银鲫消化酶活性具有正向促进作用,但在不同添加水平上,消化酶活性增强的程度不同,其适宜的添加量为0.5~0.9 g/kg。更多还原

【Abstract】 160 evenly weighted hybridized Prussian carps in the same growth phase were randomly divided into five groups, 16 carps and two replications for each group. The adding level of saccharicterpenin is 0, 0.5, 0.9, 1.2 and 1.5 g/kg respectively. Results showed that, in proper range of temperature, hybridized Prussian carps in Group 2 have the highest activity of amylase, protease and lipase, Groups 2 and 3 take the second place, and the control group the last place. The suitable temperature for protease is within 40~50℃, for amylase 30~40℃, and for lipase 30~40℃. Saccharicterpenin has positive action on the activity of digestive enzyme of hybridized Prussian carp; however, the increasing degree of digestive enzyme activity varies with different adding levels, and the suitable adding amount is 0.5～0.9 g/kg.更多还原
