ABSTRACT This study aimed to evaluate the antioxidant potential of citric acid in plant protein based-diets offered to juvenile tambaqui, Colossoma macropomum. Four isonitrogenous and isoenergetic diets containing different levels of citric acid (0, 10, 20, and 30 g.kg−1) were formulated. Fish (n = 160; 27.56±1.03 g) were randomly distributed in 310-L water tanks (n = 16), with four replicates per treatment. After the experimental period (80 days), animals were anesthetized, and blood was collected for cell count. They were […]

The effect of supplementation of acidifiers in diets for broiler chicks on performance na intestinal morphology was valuated. A total of 2,112 birds was allocated to eight diets, with six replicates, constituted by the addition of antibiotics or acidifiers blenders according to the phase development (from 1 to 7, from 8 to 21 and from 22 to 35 days old), in different composition: control – positive = bacitracin methylene disalicylate (BMD – 55 ppm) + colistin (10 ppm); control-negative = […]
