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。
One hundred and sixty-six allogynogenetic crucian carp (Carassius auratus gibelio) with the same growth stage and weight were randomly divided into five groups (16 in each group), with two replicates in each group. Saccharicterpenin levels were added at 0, 0.5, 0.9, 1.2, and 1.5 g / kg. The results showed that the protease, amylase and lipase activities of Carassius auratus gibelio crucian carp Carassius auratus in experimental group 2 were the highest in the suitable temperature range, followed by the first group and the third group, the lowest in the control group. Protease suitable temperature is 40 ~ 50 ℃, amylase suitable temperature is 30 ~ 40 ℃, lipase suitable temperature is 30 ~ 40 ℃. Saccharicterpenin could promote the activity of digestive enzymes in allogynogenetic crucian carp (Carassius auratus gibelio), but at different levels, the extent of digestive enzyme activity enhancement was different. The suitable dosage was 0.5-0.9 g / kg.
