| Popis: | Crop residues are a major source of low-quality biomass that can be fed to ruminants. Sugarcane bagasse and sugarcane pith, the residue after rind removal, are highly lignified by products of the sugar and paper industries, respectively (Muller, 1978). The low digestibility, high lignin and very low nitrogen content, are considered the main reasons for unsatisfactory performance of animals fed this roughage. Steam-pressure treatment cleavage the bounds between lignin and the other component of the cell wall, These are associated with the improved utilization of cell wall polysaccharides in the steam pre-treated materials by cell-free enzymes and enzymes of the rumen microbial ecosystem. The possibility of increasing nutritive value of fibrous feedstuffs by enzymes treatment has been studied in recent years. A number of studies in the 1960s involving cattle and sheep showed that enzymes substantially improved feed digestibility and animal performance, but results were often inconsistent The objectives of our study were to characterize the response of sugarcane bagasse, pith, untreated and steam treated, to sodium hydroxide and enzyme mixtures treatment. |
