ABSTRACT
Ruminal degradability rates for dry matter (DM), crude protein (CP) and crude fiber (CF) of Panicum maximum and Pennisetum purpureum, grasses, both fresh and artificially dried, were fixed by nylon bags in situ technique. Eight crossbred male rumen fistulated steers were used in a changover design 4 x 4, to test the following treatments A) Napier grass; B) Napier grass, dried; C) Colonião grass; D) Colonião grass, dried. Results were statistically similar and with 48 h of incubation time were the following ones DM = 42.5%, 45.9%; 52.7%; 50.7% CP = 37.9%; 53.0%; 49.7%; 46.9% CF = 32.2%; 39.7%; 40.0%; 45.2% for A, B, C and D treatments respectively.
RESUMO
As taxas de degradação ruminal da matéria seca, proteína bruta e fibra bruta dos capins Colonião e Napier, nas formas fresca e desidratada, foram determinadas pela técnica de sacos de náilon in situ. Oito bovinos machos mestiços, com fístulas de rúmen, foram usados em um delineamento em change-over com dois grupos de 4 animais, para testar os seguintes tratamentos A) capim Colonião; B) capim Colonião desidratado; C) capim Napier e D) capim Napier desidratado. As taxas de degradabilidade mostraram-se estatisticamente semelhantes e foram as seguintes, com 48 horas de incubação MS = 42,5%; 45,9%; 52,7% e 50,7%, PB = 37,9%; 53,0%; 49,7% e 46,9%, FB = 32,2%; 39,7%; 40,0% e 45,2% para os tratamentos A, B, C e D respectivamente.
