Abstract

© 2014 Universidad de Cordoba. All rights reserved.The study evaluated tambaqui, Colossoma macropomum, performance fed different levels of mango (Mangifera indica) meal in the feed (20, 30, 40 and 50 %) and the reduction of protein levels (38, 33, 28 and 23 %). To this study, 240 fish were used, separated in 12 equal groups, in four treatments and three replications in a randomized system. Initial weight was 5,21; 5,24; 5,19 and 4,99 g respectively. The trial lasted 56 days and fish were periodically weight. Fish were fed daily ad libitum. The following performance parameters were analyzed: specific growth, biomass gain; apparent fed conversion, survival, metabolic profile and digestives enzymes activity. All data show positive polynomial regression for the diet with 50 % mango meal and 23 % protein (R50). Performance parameters had a significant effect with higher results in the groups were mango meal was higher and protein level was lower. Final average weigh was R20: 8,65; R30: 8,81; R40: 8,68 and R50: 11,39 g. From metabolic profile analyzes: glucose, hepatic glycogen, total amino acids and cholesterol it was observed that there are a mobilization from these metabolites in order to keep energy process for tambaqui growth. It was concluded that the best tambaqui performance occured in the diet with 50 % of mango meal inclusion and 23 % of protein. Fish metabolic profile is positively affected by the replacement of protein by mango meal.
