Abstract: The objective of this study was to evaluate the digestive system of juvenile tambaqui fed with an experimental diet containing 28% crude protein and 3000 Kcal/kg, with an inclusion of 20% of the following ingredients: palm kernel cake, tucuma pie and coconut bran. We used 300 juveniles tambaqui (16.0± 1.5 g), distributed in 12 recirculating tanks (250L) with continuous filtration and aeration of water. The experiment design was randomized and conducted with three replicates of four treatments identified as basal diet- T1, palm kernel-T2, tucumã- T3 and coconut-T4. After feeding for 60 days portions of the mid intestine and live were fixed in bouin and processed for optic microscopy. Morphometric of intestinal villi showed that diets, T1 and T4 interfered in the epithelial microvilli height. Hepatocytes showed differences between the diets T3, T2 and T1. Hepatic changes were significant in the tucumã diet. Leading to the conclusion that a diet based on palm kernel is the most suitable to feed juveniles tambaqui.
