The study was carried out in the central highlands of Peru at 3,900 meters above sea level, in the Casaracra experimental center of the Daniel Alcides Carrión National University, where the objective was to determine and analyze the forage yield and nutritional quality of the associated grasses in different density is sowing. In forage production, the values of green matter and dry matter and the percentage of dry matter were determined; in nutritional quality, the nutritional variables% PT, %NDF, %FDA, % Ca and% P were analyzed. a completely randomized design was used. The results for forage yield for treatment 1 in MV was 3.54 kg / m2 and DM 0.68 kg / m2, in treatment 2 in MV it was 2.61 kg / m2 and DM 0.72 kg / m2, for treatment 3 in MV it was 3.07 kg / m2 and DM 0.98 kg / m2 and finally in treatment 4 the MV was 2.48 kg / m2 and DM 0.93 kg / m2. The nutritional quality for treatments 1, 2, 3 and 4 in% PT (15.56, 15.21, 6.81 and 5.37), % FDN (48.85, 43.82, 43.34 and 41.89), % FDA (28.82, 26.31, 27.27 and 24.43), % Ca (0.86, 0.80, 0.33 and 0.17), %P (0.25, 0.24, 0.18 and 0.07) respectively. Where it is concluded that treatment 4 showed acceptable fiber content in sheep feeding.
