Resumo: This work studied DM, CP and CF ruminal degradability, through nylon-bag technique "in situ", of Napier grass (Pennisetum purpureum Schum) on several growth stages. Eight rumen fistulated steers were used to compare 4 treatments: A = 72 days and 1,30 m high; B = 105 days and 2,35 m high; C = 135 days and 3,25 m high and D = 161 days and 3,25 m high, considering age and stand of grass regrowth. Experimental design was completely randonmized, and the results showed that DM, CP and CF rumen degradabilities decreased linearly with grass growth (p < 0,01). Degradability values for 48 h incubation time were DM: 56,02%; 47,71%; 43,57% and 38,76%; CF = 47,37%, 41,7%, 32,28% and 22,92% for A, B, C and D treatments. Concerning CP, only A, B and C stages were analyzed: with the following results: 53,59%, 35,32% and 26,42% for 48 h of incubation time. Rumen volume increased linearly with grass age (p <0,01) and rumen turn-over was higher for A (p < 0,05).

Foram utilizados 8 bovinos com fístulas permanentes de rúmen, o delineamento foi o inteiramente casualizado e os seguintes resultados foram obtidos: as degradabilidades da MS, PB e FB diminuíram de forma linear com o aumento da idade da planta (p < 0,05); os valores com 48 horas de incubação foram: para MS = 56,02%, 47,71% e 38,76%; para FB = 47,37%; 41,77%; 32,28% e 22,92% nos tratamentos A, B, C e D respectivamente. Para proteína, foram considerados apenas os estádios A, B e C: 53,59%, 35,32% e 26,42% de degradabilidade às 48 horas de incubação. O volume de líquido ruminal aumentou linearmente de A para D (p < 0,01), sendo que o "turn-over" líquido ruminal foi maior em A (p < 0,05).Universidade de São Paulo.
