Aiming to evaluate the effect the addition of residues in different levels on the quality of passion fruit residue silage, this study was undertaken. The residues were ensiled in experimental PVC silos, fitted with Bunsen-type valves with a capacity of about 3 kg each. The treatments consisted of three additives (sugar-cane bagasse (SCB), coffee hulls (CH) and corn cob (CC)) at four levels (10, 15, 20 and 25%) plus a control treatment without additive. The experimental design used was the completely randomized, in a factorial scheme with an additional treatment [(3 x 4) + 1] with four replicates. The silages in which SCB was added and the silages with 100% of yellow passion fruit residue had a less DM content to the recommended for a good silage. The additive CH was the only that increased the protein content of the silages. All the silages showed values of pH and N-NH3 (% total N) according to the standards which characterize a good fermentation process. The silages with 100% of passion fruit residue and with SCB or with CC added at the different levels, showed good values of DM, CP, pH and N-NH3, indicating to be an alternative in ruminant feeding in regions where passion fruit by-product is available.
