Physical, bromatological and microbiological analyzes were carried out. Four treatments (different concentrations of native-probiotic microbial preparation) were used with 2%, 4%, 6%, and 8%. The pH of the process was 3.9 and the temperature was 19 °C. The treatment with 6% of probiotic yielded the best results, with 15.39% of protein, 74.78% of humidity and 14.04% of fiber, free of pathogens like <em>Salmonella </em>sp., <em>Clostridium </em>sp., <em>Escherichia</em><em> coli</em> and molds, with and a high concentration of lactic acid bacteria (2.40E + 04 UFC.ml<sup>-1</sup>) and a cost benefit of 1.33. Milk production in crossbred Holstein cows fed with this product increased from 14.08 to 17.40 L.day<sup>-1</sup>, so we recommended using it as supplementary feed.</p> ER -
