Abstract

The conservation of auto-hydrolysed sugarcane bagasse (AHB) in small tower silos was evaluated by the effect of consolidation (500 and 600kg/m3), dry matter content (35 and 45%), hidrolysis intensity (13 and l9kgf/cm2 during 6 minutes) and storage period (0, 4, 8 and 17 weeks). Treatments were evaluated by dry matter (oven and toluene distillation), neutral detergent fibre (NDF), ether extract (EE), pH, ammonia nitrogen, in vitro digestibility (IVD) and in situ degradability (ISD) analysis. The consolidation and dry matter content had no influence on the AHB conservation. The increase on NDF content and decrease on IVD indicated biodegradation of the soluble fraction (pentoses) during the storage period. The stability of ISD data during the storage period showed that fibre fraction was not significantly hydrolysed by the microorganisms.
