The objective was to evaluate the chemical composition, fermentation characteristics and parameters of the degradation of neutral detergent fiber of three types of silage co product from the extracting of the Bactris gasipaes. Were evaluated the leaf silage, composed silage (55% of leaf and 45% of sheath) and the sheath silage. Co product was put into experimental silos, and after forty days of fermentation the mini silos were opened and silage samples collected for determination of dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber ( ADF), crude protein (CP), ash, calcium, phosphorus, pH, ammonia nitrogen (N-NH3) and volatile fatty acids. In addition to the three types of silage, corn silage and sugar cane silage were evaluated to determine the parameters of NDF degradation. The samples were evaluated at 0, 3, 6, 9, 12, 24, 36, 48, 72 and 96 hours. During the hydration process, rumen fluid was collected from a donor bovine, rumen fistulated, kept close to the incubation room. There were differences in dry matter content among the three types of silage, the same happened with the crude protein, NDFcp, ADFcp and lignin. Leaf silage showed the highest fractional degradation rate of NDF among co product silages over 96 hours of incubation, as well as the highest fraction potentially degradable NDF, however, still remaining below the corn silage. The sheath silage had the highest NDF undegradable fraction and also the lowest fraction degradation rate. The leaf silage showed the best characteristics of chemical composition, fermentation profile and recovery of the NDF in the rumen environment, proving to be a promising food in ruminant feed. The composed silage, although a lesser quality, has the advantage of using all the waste production, reducing environmental problems.
