NUTRITIONAL COMPOSITION OF CUBA OM-22 HYBRID GRASS (Pennisetum purpureum Schumach x Pennisetum glaucum L.) AT THREE CUTTING AGES

At the Central Experimental Station of Ecuadorian Amazon INIAP, nutritional composition forage Pennisetum purpureum Schumach x glaucum L was evaluated. (Cuba OM-22) in different cut-off ages (30, 45 and 60 days). There were 12 plots 6m2 each approximately six months establishment, a completely randomized block design (DBCA) used with three treatments four repetitions, variables subjected to an analysis variance, means evaluated Tukey's test at 0.05%, addition regression correlation performed. All studied except dry matter acid detergent lignin presented significant highly differences; 30 days cut-off, highest values found, ash (19.04%), ethereal extract (2.84%), protein (14.20%), FDA (34.67%) FDN (56.29%). It is concluded that Cuba OM-22, cutting age presents values, however, it considered necessary adequate management crop guarantee agronomic development persistence crop.
