Study on Effect of Dietary Protein and Lipid Levels on Growth of Procambarus clarkii
摘要
Abstract
The effects of dietary protein and lipid levels on the survival rate, growth, feed conversion ratio and muscle amino acid components of Procambarus clarkii were studied by using 4×3 double factorial design. The results indicated that the dietary protein and lipid levels had a significant influence on the weight gain rate (833.67% ~ 1091. 38% ) and feed conversion ratio (1.53 ~ 1.96) (P <0.05). The weight gain rate and specific growth rate were the highest, and the feed conversion ratio was the lowest in 28% protein plus 6% lipid group. Dietary essential amino acid content was increased with the increase in dietary protein level, and the essential amino acid content in the muscle of Procambarus clarkii ascended first and then reduced. The contents of total amino acid and essential amino acid in the muscle were the highest in 24% protein plus 6% lipid group, and was the lowest in 32% protein ＋ 4% lipid group. Moreover, in 28% protein ＋ 6% lipid group, the muscle contained more four delicate flavour amino acids (Asp, Glu, Gly, Ala). In conclusion, the author suggests that the optimal levels of dietary protein and lipid for Procambarus clarkii are 24% ~28% and 6% , respectively.关键词
