Influence of Substitution Effect of Fat and Protein in Feed on Crucian Carp

HU Xue-feng et al(Fisheries and Life College,Shanghai Ocean University,Shanghai 200090)  
[Objective]The study was to provide the reference for feed formula adjustment for feed enterprise.[Method] With founder crucian carps as the tested materials,they were given different feed(A:3% fat in B was replaced by 6% protein;B:protein of 37%,fat of 6%,energy of 16.2 MJ/kg;C:6% protein in B was replaced by 3% fat),the growth performance,morphological index,body compositions and serum nonspecific indexes of crucian carps in different groups were compared.[Result] The specific growth rate and crude protein content of crucian carp and the cost per 500 g crucian carp in group A were decreased by 3.21%,8.64% and 4.63%(P0.01)than those of crucian carps in group B resp.,but feed coefficient of group A was increased by 5.00%(P0.01)than that of group B.The body moisture and serum aspartate aminotransferase(AST) activity of crucian carp and the cost per 500 g crucian carp in group C were increased by 1.41%,17.38% and 9.24%(P0.01)than those of crucian carps in group B resp..[Conclusion] Feed A decreased growth performance of crucian carp.Feed C had no significant effect on growth performance of crucian carp,but increased the production cost of crucian carp.
