Somatic cell counts (CCS), bacterial counts (CBT), fat and protein were quantified to evaluate milk quality. It was verified that the silage samples were with high percentage of ash, which causes loss in their quality. There was no difference between levels of gross protein technology. The CCS of the SE system was 392.40 higher than in the ES, CBT obtained higher value in ES. All variables are within the limits required by IN 62.
