Napier grass (Pennisetum purpureum Schum) in-3 growing stages: a) 1,30 m tall and 17.54% dry matter; b) 2.35 m tall and 25.84% dry matter: and c) 3,25 m tall and 26.31% dry matter, was fed "ad libitum" to eight rumen fistulated steers all crossbred (5/8 european-zebu) weighting 220 kg, being fed 1,5 kg of a concentrate meal with 24.16% of crude protein. Treatments were compared in a completely randonmized design using the 4th week of each experimental period for rumen liquor sampling for differencial counts of the following protozoa: Entodinium, Diplodinium, Eudipiodinium and Polyplastron. Results showed Entodinium as 96.73% of total protozoa and its concentration per mililiter of rumen fluid decreased linearly as the plant matured (a = 18.2 x 104/ml; b = 12.1 x 104/ml; and c = 9.8 x 104/ml).Downloads
