PIMENTA, C.J. et al. Profiting coffee residue in feeding of Nile tilapia. Arch. zootec. [online]. 2011, vol.60, n.231, pp.583-593. ISSN 1885-4494.

This work evaluated different ways to include residues from coffee in Nile tilapia ration. Three assays were conducted: 1-rations chemical composition; 2-digestibility and 3-tilapia performance fed with different ways to include residues of coffee on ration. The following treatments were tested: T1-basal ration; T2-stove pre-dried coffe residue ration; T3-ration with residue from coffee maintained under aerobic conditions added serum of milk and nolasses; T4-ration with acid ensilage of residue from coffee with formic acid; T7-ration with ensilage of residue from coffee with serum of milk. Those residues replaced 30% of the basal ration. The physical form of the ration was pelleted. The treatment T5 resulted in greater weight gain and feed consumption and lesser feed conversion. The treatments T1 and T2 did not defer between itself presenting close values to the T5. The treatments T6 and T7 presented lesser weight gain and ration consumption and greater feed conversion.

Keywords : Ration; Digestibility; Performance; Chemical composition; Oreochromis niloticus.
