Abstract

This experiment was conducted at Estação Experimental de Zootecnia in Pindamonhangaba county, State of São Paulo, Brazil. Dry matter and crude protein production and nutritive value of Uruckwami elephant grass were studied, during two years, under eight cutting frequency: 35, 42, 49, 56, 63, 70, 77 and 84 days, in the period of greatest growth, from september to june. The results of dry matter and protein production and the percentages of the forage components determined in the first year were higher (P <0.05) than those observed for second year. There was an increase of production and decrease of forage quality with increasing cut interval. In the first year the longest period, 84 days, presented the greatest production 41.0t/ha of dry matter and 4.1t/ha of crude protein and the lowest protein and TDN contents (9.6 and 50.4%, respectively). Cuts effected at 49 and 56 days provided good forage production with the best quality.
