Chemical stability of diets to aquatic organisms with nutritions binders

Abstract

The experiment was conducted in the Research Laboratory on Nutrition of Aquatic Organisms - a unit integrated to the Aquaculture Center of UNESP at Faculdade de Medicina Veterinária e Zootecnia, "Campus" de Botucatu, aiming to evaluate the physical -chemical stability of nutritional binders in diets to aquatic organisms. The experimental design was completely randomized, with factorial: 3x3 (levels: 3, 6 and 9%) x (sources: wheat meal, manioc meal and wheat flour), plus a control treatment, with five replicates. When the chemical leaching (CP, EE, MM) was studied, the manioc meal showed, generally, the bigger leaching percentage when compared to the control and wheat meal and wheat flour, in the three Ievels. The added levels of 3, 6 and 9% of wheat flour or 3 and 6% of wheat meal resulted in better CP, EE and MM fractions, when compared with control and manioc meal. It was concluded that nutritional binders, especially wheat meal, could be utilized in the preparation of aquatic organisms feeds.
