Abstract

Digestion trial was conducted in order to determine the production and nutritive value of a Jaraguá grass (Hyparrhenia rufa (Nees) Stapf.) pasture, during the dry season, in São Paulo State, Brazil. Three young crossbred Zebu x Holstein bulls were kept in cages during ten days for collection, after eight days of adaptation period to the forage. Fresh chopped grass was fed to the animals after 240, 300 and 360 days growing periods. Percent digestion coeficientes found were as follows: after 240 days D.M. 50.82; C.P. 18.18: C.F. 59.66; E.E. 57.87; N.F.E. 51.09 and T.D.N. 51.37; after 300 days: D.M. 35.05; C.P. 0.0; C.F. 51.14; E.E. = 43.58: N.F.E. 31.69 and T.D.N. 38.26, after 360 days: D.M. 45.66; C.P. 0.0, C.F. 57.69: EE. 2974; N.F.E. 44.37 and T.D.N. 46.00. The estimation of dry matter availability was as follows: after 240 days, 13,850kg/ha; after 300 days, 17,120kg/ha and after 360 days, 10,560kg/ha.
