中文摘要:
      为研究牛磺酸对花鳗鲡幼鳗生长和消化酶活力的影响,在基础饲料中分别添加0%、0.20%、0.40%、0.60%、0.80%的牛磺酸,配制成牛磺酸含量为0.708%、0.908%、1.108%、1.308%、1.508%的5组试验饲料(D1,D2,D3,D4和D5),投喂体质量为85.95 g的花鳗鲡幼鳗14周。结果表明:(1)随着牛磺酸含量的升高,花鳗鲡体质量呈先上升后下降的趋势,并在D4组达到最高值;D4组的增重率、特定生长率显著大于D1和D2组(P<0.05),饵料系数显著低于D1和D2组(P<0.05)。(2)相比于D1组,高牛磺酸含量组花鳗鲡肌肉中水分的含量降低,粗蛋白、粗脂肪和灰分的含量升高,其中D3组的粗蛋白含量显著大于D1组(P<0.05)。(3)饲料中适量的牛磺酸含量(1.108%~1.308%)能显著提高花鳗鲡胃和肝脏中的淀粉酶、蛋白酶活力以及肝脏中的脂肪酶活力(P<0.05)。综合以上结果,花鳗鲡幼鳗对牛磺酸的需求量为1.308%。
英文摘要:
      A 14-week feeding trial was conducted to evaluate the effects of dietary taurine on growth and digestive enzyme activity of Anguilla marmorata with initial body weight 85.95 g. Five experimental diets, which were formulated with 0%, 0.20%, 0.40%, 0.60% and 0.80% taurine respectively, and contained 0.708%, 0.908%, 1.108%, 1.308% and 1.508% taurine (named D1, D2, D3, D4 and D5). The results showed that: (1)With the increasing of dietary taurine, the final weight of the fish first increased then deceased and peaked in D4 group. The weight gain rate (WGR) and specific growth rate (SGR) in D4 group were significantly higher than those in D1 and D2 groups. (2)Crude protein, total lipid and ash contents in muscle were increased and moisture was decreased along with the increasing dietary taurine levels, the crude protein content in D3 group was significantly higher than that in D1 group. (3)The fish fed the diets with 1.108%-1.308% taurine displayed significantly higher amylase activity and protease activity in stomach and intestine and higher lipase activity in liver. It is therefore suggested that the optimum dietary taurine level for Anguilla marmorata is 1.308%.
