Palm heart processing generates a large amount of residues like leaves, sheath and stems that have potential for ruminant feeding. This study aimed to evaluate the effect of in natura peach palm heart (Bactris gasipaes Khunt.) residues on performance, dry matter (DM) digestibility and intake of ruminants. External sheath was the most suitable residue for sheep, cattle and buffaloes feeding, although sheep presented rejection of 43.5 g kg-1. Thereby, assays of apparent and in vitro dry matter digestibility were done under four feeding treatments, which were the exclusive peach palm sheath, and that one mixed with residues of banana and rice, besides citrus pulp. The experiment was carried out under randomized complete design, with five replications. Greater DM intake (p 0.05). Cattle and buffaloes accept different types of peach palm residues, unlike sheep that present a low rejecting for them. Citrus pulp and rice residue raise the roughage quality. Peach palm residues can be an alternative roughage source to feed ruminants.
