Avaliação de alimentos alternativos para o tambaqui na região Norte Mineira

Abstract

This study aimed to evaluate the apparent digestibility coefficient (ADC) of the protein and energy present in the alternative foodstuffs to the tambaqui in the northern region of Minas Gerais. They were used 90 tambaqui, with an average weight of 750,79 ± 209,54 g, distributed in 18 incubators of fiber of glass of 200 liters adapted for feces collect (modified Guelph). They were used five alternative foods: banana peel, leucaena leaf, manioc leaf, almond pie and of the macauba pulp. The determination of the ADC were performed by the indirect method and is used as an indicator 0,1% of chromium oxide (Cr2O3) incorporated into the ration. The ADC of crude protein and raw energy for the banana peel, leucaena leaf, manioc leaf, almond pie and of the macauba pulp were: 58,24 and 20,91%, 44,64 and 28,19%, 68,67 and 34,23%, 79,89 and 42,09%, 87,49 and 62,67%, respectively. The residues of the macauba showed the best apparent digestibility coefficients of the protein and energy.
