Summary:It was aimed in this study to evaluate the ensiled pejibaye residue in the feeding of ruminants as roughage. For the in vitro digestibility assay, a randomized block design was used, with four treatments (pejibaye residue without additives; pejibaye residue + banana residue; pejibaye residue + rice residue and pejibaye residue + citrus pulp), with four replications. The variables studied were: chemical composition, specific mass, pH, average particle size, fermentation temperature and fermentative losses. Apparent digestibility was performed with sheep in a completely randomized design, to evaluate the same treatments mentioned above, using five replications. Heart-of-palm pejibaye residue silages showed average particle size, pH and density values within the range appropriate for their manufacture. Among the additives used in this study, silage with 15 g/100g of rice provided improvements in several nutritional parameters, such as DM, NDF, ADF, CF and NDF/NFC. High moisture content impairs the ensiling process, but it was solved with high dry matter content ingredients addition to promote the material stability.
