天蚕素抗菌肽对网箱养殖鲤鱼生长性能的影响

Effects of cecropins on the growth performance of common carp cultured in cages

为研究天蚕素抗菌肽对水产动物生长性能的影响,选取2700尾体质量约57g的鲤鱼进行试验,分别设置对照组、试验1组和试验2组。试验组在对照组饲料基础上分别添加100mg/kg和200mg/kg的天蚕素抗菌肽,进行为期30d的试验,观察鲤鱼生长和摄食情况。试验结果发现,与对照组相比,添加天蚕素抗菌肽可显著提高鲤鱼体质量和特定生长率。

To study the effects of cecropins on the growth performance of aquatic animals, 2700 common carp with body weight of about 57 g, were selected and randomly divided into 3 groups(control group, group 1 and group 2).On the basic diet of the control, 100 mg/kg and 200 mg/kg cecropins were added to group 1 and group 2, respec-tively. During 30 d test period, growth and ingestion of common carp were observed. Compared to the control group, the addition of cecropins significantly improved fish weight and specific growth rate of common carp.
