Abstract

The proper utilization of dietary carbohydrates and the protein sparing effect result in decreased production costs and reduced nitrogen excretion. Therefore, studies are being conducted to analyze this possible sparing effect of dietary protein. Accordingly, the carbohydrate diet enables the dietary protein for maximum growth. The pacu (Piaractus mesopotamicus) represents an interesting biological model, as frugivore, allowing a better utilization of carbohydrates. Thus, will be studied the hepatic activity of glucokinase (GK), pyruvate kinase (PK) and fructose-1 ,6-bisphosphatase (FBPase) of pacu juveniles that were fed with six experimental diets (23/40, 19/45; 19/52, 21/38, 21/45 and 21/52% / PD% CHO). The results will be submitted to analysis of variance (ANOVA) and the means were compared by Duncan test (5%), through the SAS statistical software, version 9.0. (AU)
