Currently, livestock production in the Andean highlands of Bolivia is done with low food efficiency due to the free range grazing system. This in turn leads to nutritional deficiencies. Therefore, it is necessary to substitute these grass species for others that fulfill nutritional requirements. Our main objective was to determine the species of grass with the best nutritional quality. Of the 12 species, only 11 were analyzed because the species Didtichlis stricta did not germinate. Five monthly samples were taken after the cut (ddc) at the following intervals: 50, 81, 112, 141, and 176 days. These samples were analyzed in the Laboratory of Animal Nutrition via the Weende method. After analyzing the results statistically, it was determined that Agrophyrum elongatum and Festuca aranduniceae were the species that had the highest dry matter yields (9.74 and 8.78 t/ha-1 respectively). In addition, they had higher content of ash, fats, protein, fiber carbohydrates, total digestible nutrients, and digestible energy than the other species also considered as forage with good nutritional quality. We also found that dry matter yield was highest at 209 and 193 days after the cut (ddc)
