Resumo: |
Fruit residues represent alternative ingredients that can be included in diets for tambaqui, Colossoma macropomum. This study evaluated the zootechnical performance of tambaquis fed diets with different levels of inclusion of guava agroindustrial residue. The experiment was conducted in a completely randomized design, randomly distributed 105 fish in 15 plastic boxes of 60 L with water recirculation system. Feeding was carried out to apparent satiety for 45 days, using diets with 0, 5, 10, 15 and 20% inclusion of the guava residue. Biometrics were performed every 15 days. Quadratic effect (P < 0.05) was observed for daily feed intake and feed conversion, with ideal levels of 4.86 and 6.05% inclusion of guava residue, respectively. There was no significant difference (P > 0.05) in relation to final weight, weight gain, specific growth rate, hepato-somatic index, survival rate and protein efficiency ratio. The inclusion of up to 15% of the guava agroindustrial residue in the feed did not compromise the performance of tambaqui juveniles. |
