Different particle sizes and storage times in silage from cassava foliage
Abstract
The objective of this study was to observe the influence of different particle size and times of storage on the chemical composition of silage from cassava foliage (Manihot esculenta Crantz, 1766). The experiment was done in the Enzymology Applied and Analysis Bromatological aboratory of Chemical and Biotechnological Institute of the Federal University of Alagoas. The vegetal material used was bout 20 months old. The material was chopped to provide three particle sizes (1.5, 2.5 and 3.5cm) and a control (without any cut), compacted in micro-silos and stored for four different times (3, 15, 30 and 45 days). After the storage period, the samples were collected for analysis of dry matter, ash, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, lignin, pH and buffer power. During this period, the presence of leaching was observed in some treatments, however in small quantity, which was not computed. The control treatment showed the best values for chemical composition and the best storage time was 30 days. After this period, spoilage was detected. Around the end of the experiment, the particle size and storage time was observed to have no relationship with the variables that were studied, except for crude protein.Downloads
