AVALIAÇÃO MICROBIANA DE SILAGEM DE COPRODUTO DE FECULARIA DE MANDIOCA E VITIVINICULTURA EM DIFERENTES PROPORÇÕES ATÉ 60 DIAS DE ARMAZENAMENTO

The objective of this study was to evaluate the microbial population of cassava starch coproduct silage (CSC) and vitiviniculture (CV) in different proportions up to 60 days of storage. The evaluated treatments were the proportions of vitiviniculture coproduct in the silage of coproduct of cassava starch extraction (0%, 25%, 50%, 75% and 100%). The silages were evaluated at the time of ensiling and at 1, 3, 7, 15, 30 and 60 days. The experimental design was completely randomized with five treatments, six storage times and four replications. There was low proliferation of enterobacteria and yeasts at all storage times and treatments. The population of Clostridium spp. reduced with storage time for all silages. Acid-lactic bacteria showed good proliferation at all times and treatments. All silages presented good quality in relation to microbiological parameters up to 60 days of storage.
