为了研究配合饲料中添加不同水平大麦虫粉对锯缘青蟹的生长性能和消化酶活力的影响,试验采用单因素试验设计,设4个组,在饲喂基础日粮的基础上分别添加4%、8%、16%、32%的大麦虫粉,每组设3个重复,每个重复100只蟹。进行45 d的饲养试验,分3个试验期。结果表明:大麦虫粉添加浓度为16%时锯缘青蟹的生长性能最好;大麦虫粉添加浓度为8%时,其蛋白酶和淀粉酶活力最高。
In order to study the effects of adding different levels of barley dust on the growth performance and digestive enzyme activities of mixed crab, the experiment adopted the single-factor experimental design and set up four groups. Four groups were fed with basal diet supplemented with 4 %, 8%, 16%, 32% of barley dust, each with 3 replicates, each repeating 100 crabs. 45 days of feeding trials, divided into 3 test period. The results showed that the growth performance of Scylla serrata was best when the concentration of barley dust was 16%, and the activity of protease and amylase was the highest when the concentration of barley dust was 8%.
