摘要:
研究了饲料脂肪水平对曼氏无针乌贼生长性能和饲料利用率的影响.试验以鱼油为脂肪源，配制脂肪水平分别为6%、8%、10%、12%和14%的5种饲料，对平均初始体重为（1.45±0.15）g的曼氏无针乌贼进行为期60 d的饲养实验，在饲养30 d和60 d时各取样一次进行分析.结果表明：在饲养30 d和60 d时，随着饲料脂肪水平的升高，曼氏无针乌贼的相对增重率、肝体比、肥满度、特定生长率、饲料转化率、蛋白质效率和成活率都呈抛物线变化，但相对增重率、特定生长率、饲料转化率、蛋白质效率和成活率差异显著（P<0.05），肝体比和肥满度差异不显著（P>0.05）.综合各项指标并分析特定生长率、饲料转化率、蛋白质效率和成活率的回归关系，推测曼氏无针乌贼配合饲料中适宜的脂肪水平为8.92%～9.19%.
Abstract:
The present study evaluated the effects of dietary lipid levels on the growth and feed utilization of Sepilla maindroni whose average weight were (1.45±0.15) g.Five experimental diets were evaluated，with different fish oil fat levels of 6%，8%，10%，12% and 14%.During the 60-day feeding experiment，individuals with 30 days and 60 days treatments were sampled to analyze the dietary effects，respectively.The results showed that relative weight-gaining rate，liver to body ratio，fullness，specific growth rate，feed conversion efficiency，protein efficiency ratio and survival rate of S.maindroni were parabolicly related to the increase of dietary lipid levels in both the 30 d and 60 d treatments.Weight gain rate，specific growth rate，feed conversion efficiency，protein efficiency ratio and survival rate showed significant(P<0.05) differences in the different lipid levels，respectively.While liver and body ratio and fullness were not significantly(P>0.05) affected.The dietary lipid levels ranging from 8.92%~9.19% appears to meet the lipid requirement for S.maindroni，as reaveled by the analyses of the indicators and the regression analysis between specific growth rate，feed conversion efficiency，protein efficiency ratio and survival rate.
