Chemical and microbiological evaluation of ensiled sugar cane with different additives BJM
Bravo-Martins,Claudia Eugênia Castro; Carneiro,Heloisa; Castro-Gómez,Raúl Jorge Hernán; Figueiredo,Henrique César Pereira; Schwan,Rosane Freitas.
Sugar cane silage has a potential for animal feeding, but uncontrolled growth of undesirable microorganisms may cause nutritional losses and affect the animal productivity and health. The objective of this work was to evaluate the microbiological quality and chemical composition of ensiled sugar cane with and without nutritional additives after 30 days of fermentation. Yeasts, filamentous fungi and distinct groups of bacteria were enumerated by plate count methods and the chemical analyzes comprised dry matter, crude protein, fiber content, lignin, and pH. Facultative aerobic bacteria and filamentous fungi were not detected during the fermentative process in any of the treatments. The number of yeasts in five varieties of sugar cane silage without...

The objective of this study was to evaluate the effect of sugar cane ensilage with different Brix degrees, with or without the addition of 0.5% of calcium oxide (lime) on the chemical composition and fermentation losses of silages. A complete random design in a 9 × 2 factorial arrangement was used. Experimental silos were used, ensilage was done every 15 days with Brix measuring, and they were opened after 30 days of fermentation. As the Brix degree of the ensiled material increased, the contents of dry matter (DM) increased and contents of ash, crude protein (CP) and fibers (neutral and acid detergent fiber corrected for proteins - NDFap and ADFap) reduced. After fermentation, DM content of the silage presented a linear increase with the Brix degree...
