The objective of this study was to reduce the level of the biological marker Cr2O3 in animal diets, due to the sensibility of the sdiphenylcarbazide spectrophotometric method for chromium determination in feces, recently developed. Six levels of marker, chromium (III) oxide (0.01% – 0.02% – 0.03% – 0.05% – 0.1% and 0.2%), were incorporated into isoproteic and isoenergetic diets, for the apparent digestibility assay of the “piauçu” (Leporinus macrocephalus), in a design of entirely randomized groups. Feces were collected during […]
