The nutritive value and fermentation quality of palisadegrass (Brachiaria brizantha cv. Xaraes) and stylo (Stylosanthes capitata × S. macrocephala cv. Campo Grande) mixed silages were evaluated. The experiment was analyzed in a factorial scheme (5 × 2) in a completely randomized design using increasing levels of stylo (0, 25, 50, 75 and 100% on a fresh matter basis) on palisadegrass silages, with and without microbial inoculants (MI). With the increased ratio of stylo in mixed silages, dry matter (DM), crude protein (CP), acid detergent fiber (ADF), and lignin content increased in silages. The presence of MI promoted lower DM content, and higher neutral detergent fiber corrected for ash and protein, ADF and lignin content. The acid detergent insoluble nitrogen content and the lactic acid bacteria populations were not affected by treatments. The in vitroDM digestibility was affected by the interaction of levels of the stylo and MI. The pH, NH -N/total nitrogen and butyric acid concentrations decreased with increasing levels of stylo. Better nutritive value and quality of fermentation was found in the silage containing higher proportions of this stylo mixed with palisadegrass. The microbial inoculant evaluated did not alter the nutritive value or quality of the fermentation of the silages in this experiment.
Coffee husk is a residue generated in large amount in Brazil and which contains caffeine and tannins, among other compounds, resulting in disposal problem. Recently, studies have shown that coffee husk can be used as substrate for mushroom cultivation. However, the main problem seems to be a low mushroom yield. Moreover, sterilization was always performed, making difficult the mushroom cultivation dissemination in deprived regions. Here, the viability of alternative methods was evaluated using lime immersion and boiling, to produce Pleurotus ostreatus mushrooms in coffee husk of two varieties. These alternative methods produce mushrooms with higher or similar yield as compared to sterilization method. Therefore, immersion of the substrate in water for removing toxic compounds, careful control of moisture in the substrate, and selection of strains adapted to growth in coffee husk seems to be efficient approaches to improve mushroom yield.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
