English abstract With this study, we aimed at evaluating the nutritional value and chemical composition of forage legume intercropping with elephant grass (EG) + spontaneous growth species (SGS) + annual ryegrass (AR) + peanut forage (PF), as treatment T1; and EG + SGS + AR + red clover (RD), as T2. The EG was planted in 4-m spaced rows. The annual ryegrass was planted between the EG rows during the cool season; the RC was sowed and the PF was preserved. The experiment was performed between October 2009 and April 2010, with six grazing cycles. Samples of forage legume was collected, under simulated the grazing, to determine the levels of organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), organic matter in situ digestibility (OMISD), total phenols (TF), total tannins (TT), and condensed tannins (CT). The mean values of OM, CP, NDF, OMISD, TF, TT and TC were 90.8, 20.96, 48.38, 86.68, 1.92, 1.42 and 1.39%; and 91.84, 21.41, 41.36, 85.18, 1.90, 1.31 and 0.17% for peanut forage and red clover, respectively. Higher values (p < 0.05) were observed in the level of CT of peanut forage
Portuguese abstract Com esta pesquisa, objetivou-se avaliar o valor nutritivo e a composição química da forragem de leguminosas consorciadas com o capim elefante (CE) + espécies de crescimento espontâneo (ECE) + azevém anual (AZ) + amendoim forrageiro (AF), como tratamento T1; e CE + ECE + AZ + trevo vermelho (TV), como T2. O CE foi estabelecido em linhas afastadas a cada 4 m. O azevém anual foi estabelecido entre as linhas do CE durante o período hibernal; o TV foi semeado e o AF foi preservado. O experimento foi realizado entre outubro de 2009 e abril de 2010, sendo realizados seis pastejos. Foram coletadas amostras de forragem das leguminosas, simulando o pastejo, para determinação dos teores de matéria orgânica (MO), proteína bruta (PB), fibra em detergente neutro (FDN), digestibilidade in situ da matéria orgânica (DISMO), fenóis totais (FT), taninos totais (TT) e taninos concentrados (TC). Os valores médios de MO, PB, FDN, DISMO, FT, TT e TC foram de 90,8; 20,96; 48,38; 86,68; 1,92; 1,42 e 1,39%; e de 91,84; 21,41; 41,36; 85,18; 1,90; 1,31 e 0,17% para o amendoim forrageiro e trevo vermelho, respectivamente. Valores superiores (p < 0,05) foram observados no teor de TC da forragem do amendoim forrageiro
