Effect of rations of different lipid levels on the growth, food conversion efficiency and lipid contents of the common carp (Cyprinus carpio L.)

摘要: Five diets differing in their lipid level were prepared. The control diet was commercially available Koi carp pellet. experimental formulated from fish meal, eggs and a additive. levels A, B, C, D E 8.31%, 6.11%, 8.85%, 13.51% 17.96%, respectively. killed initial final lengths weights used to determine growth food conversion efficiencies. Samples of muscle viscera removed analyzed for content. There no significant differences the indices efficiencies five due protein sparing effects contents or fed diets. feed not high enough have detrimental on they may result beneficial consequences. findings present investigation are line with previous research.
