J. A.  aApparent digestibility of conventional and alternative feedstuffs by hybrid tambacu juveniles.h[electronic resource]  c2018  aAbstract: The apparent digestibility coefficients (ADC's) of dry matter (DM), crude protein (CP), and gross energy (GE) of conventional feedstuffs (cottonseed meal-CSM, soybean meal-SBM, wheat bran-WHB, corn-COR) and regional alternative feedstuffs (common bean residue meal-CBR, mesquite meal-MES, pasta by-product meal-PBM) were determined for hybrid juvenile tambacu Colossoma macropomum × Piaractus mesopotamicus. The apparent DM and GE digestibility of feedstuffs decreased (p&lt0.05) as fiber content of the ingredients increased. No differences (p&gt0.05) were found among ADC's of PBM and COR. The lowest CP ADC among energy sources was observed in MES; the lowest CP ADC among plant protein sources was observed in CBR. Information about the ADC's of conventional and alternative feedstuffs for tambacu is essential to formulate low-cost diets and can contribute to regional development.  aDigestibility  afish nutrition  aFreshwater fish  aAlimento alternativo  aAlimento para animal  aDigestibilidade  aNutrição animal  aPeixe de água doce  aCharacin  aHybrid fish  aNutritional value  aTambacu1 aARAUJO, T.
