Resumo: |
The objective was to evaluate the apparent digestibility coefficients of crude protein, gross energy and total phosphorus of protein concentrated foods: soybean bran, toasted whole soybeans, babassu bran and energy concentrates: corn, wheat bran, brown rice bran, grits of rice and whole cassava zest for tambaqui (Colossoma macropomum) and Nile tilapia (Orchromis niloticus). 72 specimens of tilapia and 72 specimens of tambaqui were used with an average initial weight of 198.15 ± 3.11 grams, distributed in a factorial scheme consisting of 16 treatments (2 species x 8 foods) and three replications. The indirect method of feces collection was used by decantation and chromium oxide (Cr2O3) as an inert indicator added to the test diet (70% of reference diet + 30% of the evaluated food) at a concentration of 0.1 For both species, the highest apparent digestibility coefficients for crude protein (CDAPB), gross energy (CDAEB) and total phosphorus (CDAFT) were obtained with soybean bran (93.66%), whole cassava zest (84.38%) and whole cassava zest (85.40%), respectively. For both species, the lowest apparent digestibility coefficients for crude protein (CDAPB), gross energy (CDAEB) and total phosphorus (CDAFT) were obtained with brown rice bran (78.37%), babassu bran (28.60%) and brown rice bran (16.00%), respectively.The foods present similar CDAPB and CDAEB in both species, with the exception of brown rice bran. The foods present similar CDAFT only in brown rice bran, whole cassava zest and toasted whole soybeans. |
