%X Avaliou-se a degrada  o ruminal da fibra em detergente neutro (FDN) e em detergente ¨¢cido (FDA) de silagens de milho sem espigas (SMSE) com cana -de-a ¨²car (CA) e baga o seco de mandioca (BSM), comparadas com a silagem de milho com espigas (SMCE). Os alimentos foram ensilados com (CI) e sem inoculante (SI) - Lactobacillus plantarum e L. paracasei ssp. paracasei. Estudaram-se: as fra  es sol¨²vel (A), potencialmente degrad¨¢vel (B) e n o-degrad¨¢vel (C); a taxa de degrada  o da fra  o B (c); a degradabilidade efetiva (DE) e potencial (DP). Os tratamentos foram: T1 (SMSE + 20% CA-SI); T2 (SMSE + 20% CA-CI); T3 (SMSE + 35% CA-SI); T4 (SMSE + 35% CA-CI); T5 (SMSE+ 20% BSM-SI); T6 (SMSE + 20% BSM-CI); T7 (SMSE + 35% BSM-SI); T8 (SMSE + 35% BSM-CI); T9 (SMCE-SI) e T10 (SMCE-CI). M¨¦dias foram comparadas em um delineamento inteiramente casualisado. As mai ores (p<0,05) fra  es B da FDN foram verificadas nos tratamentos T7 (B = 74,8%), T8 (B = 70,2%), T6 (B = 66,2%) e com a menor adi  o de CA, ou seja: em T2 (B = 65,0%). N o houve diferen a (p >0,05) para a fra  o C da FDA dos tratamentos T3 (C = 20,7%), T4 (C = 22,6%), T9 (C = 22,7%) e T10 (C = 24,0%). Os resultados indicam que h¨¢ possibilidade para a inclus o do BSM no lugar das espigas de milho verde para a produ  o de silagem at¨¦ o n¨ªvel de 35%. This study aimed to evaluate the ruminal degradation of corn silages without spikes (CSWS), with addit ion of sugar cane (SC) and dry manioc pulp (DMW), compared to corn silage (CS). The feeds were ensiled with (WI) and without (IF) inoculants - Lactobacillus plantarum and L. paracasei ssp. paracasei. The following fractionswere studied: water soluble (A), potentially degradable (B), non degradable (C), fraction B degradable ratio (c); effective (ED) and potential (PD) degradability. The treatments evaluated were: T1 (CSWS + 20% SC -IF); T2 (CSWS + 20% SC-WI); T3 (CSWS + 35% SC-IF); T4 (CSWS + 35% SC -WI); T5 (CSWS + 20% DMW-IF); T6 (CSWS + 20% DMW-WI); T7 (CSWS + 35% DMW -IF); T8 (CSWS + 35% DMW-WI); T9 (CS-WI) and T10 (CS-IF). The average differences were compared on a completely randomized model. Higher (p<0.05) B fractions for FDN were observed for T7 (B= 7 4.8%), T8 (B= 70.2%), T6 (B= 66.2%) and where the low sugar cane level was added on silages, that is, T2 (B= 65.0%). No differences (p >0.05) were observed between ADF C fraction for T3 (C=20.7%), T4 (C= 22.6%), T9 (C= 22.7%) and T10 (C= 24.0%). Results in dicate the possibility to include DMW on corn silage, instead of green spikes, to the level of 35%.
