Avaliacao nutricional do subproduto da agroindustria de abacaxi como aditivo de silagem de capim-elefante


The present study aimed to determine the nutritional value of mixed elephant grass (Pennisetum purpureum) silages in increasing levels with dehydrated pineapple industry byproduct (PAB). Five PAB levels (0.0, 3.5, 7.0, 10.5 and 14.0%) were tested in 20 male non-castrated sheep in a randomized experimental design of 5 treatments (PAB levels) and 4 replications per treatment (sheep). Intake and digestibility of dry matter (DM), crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF), cellulose (CEL), hemicellulose (HCEL) and energy as well as nitrogen balance were determined. Linear increases on the DM, CP intake and digestible energy occurred as the PAB content increased in the silage. For every increase of 1% of PAB in the silage, increments of 16.17 and 1.55 g of DM and CP intakes, respectively, were observed. The addition of PAB in the silage increased the DDM, DCP and DE intake. However, the nutrient digestibility remained unchanged. Mean values were 53.3, 42.1, 55.2% and 2.92 g/day for DM, CP, NDF and NB, respectively. NB was positive only with PAB in the rations. In conclusion, additions of PAB in elephant grass silage up to a level of 14% on a natural basis increases the digestible nutrient intake.
