The objective of this research was to evaluate three grazing systems (GS) with elephant grass (EG) + ryegrass (RG) + spontaneous growing species (SGS); EG + RG + SGS + forage peanut (FP); and EG + RG + SGS + red clover (RC), in order to use the area in rotational grazing during the agricultural year. EG was planted in rows with a distance of 4m between each row. In the cool-season, RG was sowed between EG rows and FP was preserved on GS. The experimental design was completely randomized with three treatments (GS), two replicates (paddocks) and independent evaluations (grazing cycles). For the evaluation lactating Holstein cows receiving 1% of BW/day feed supplement concentrate were used. The herbage mass, botanical composition of pasture, structural component of EG and stocking rate were evaluated. Eight grazing cycles were performed during the experimental period. Grazing systems involving grass and legume forage in different cycles provided the use of the area during the agricultural year in rotational grazing with dairy cattle. Considering the predominance of the evaluations in each grazing, the mixed grazing systems have better results for both forage mass and stocking rate variables.
