Resumo: This experiment utilized four one-hectare paddocks, grazed by thirty-two crossbreed steers (345kg mean initial weight) with or without supplementation. Production estimation and forage sampling were taken every 28 days in four places of each paddock. Chemical analyses were conducted for green leaf blade (GLB), leaf sheath + green stem (LSGS) and dead material (DM) fractions. Variations were observed on participation of GLB, LSGS and DM fractions and in CP and NDF concentration. The forage mass showed negative correlation with CP and IVDDM. The crude protein partition showed most significant for GLB fraction B3; for LSGS and MM, fractions A and B2 were superior (p<0.05). The highest observed values for carbohydrate partition were on B2 fraction, but occurring more A + B1 fraction in GLB, B2 in LSGS and MM and C fraction in DM (p<0.05).

As coletas de forragem foram realizadas a cada 28 dias. As estimativas de produção e análises químicas foram efetuadas para os componentes estruturais lâmina verde (LV), bainha + colmo verde (BCV) e material morto (MM). Foram observadas variações na participação dos componentes estruturais LV, BCV e MM e nos teores de PB e FDN. Correlações negativas foram encontradas entre a massa de forragem e a PB e DIVMS. O fracionamento da proteína bruta apresentou para LV a fração B3 como mais usada, para a BCV e MM a fração A e B2 foram superiores (p<0,05). Para o fracionamento dos carboidratos, os maiores valores foram para fração B2, ocorrendo maior fração A+B1 na LV, fração B2 na BCV e MM e fração C no MM (p<0,05).Editora da Universidade Estadual de Maringá2008-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/172710.4025/actascianimsci.v26i4.1727Acta Scientiarum.
