Resumo: | This experiment was carried out in Arenito Research Center-UEM, in Cidade Gaúcha-PR, from October/1997 to March /1998, to evaluate in coastcross-1 (Cynodon dactylon (L.) Pers) grazing, in four levels of dry matter residue (DMR: 1,978; 2,130; 2,545; 3,857 kg of DM/ha), with a continuous allotment system and variable number of allotments, the densities and participation of botanical component. A completely randomized design with two replications was used. Forage density, participation of botanical components and leaf/stem ratio were evaluated in inferior strata (0-10 cm) and superior ones (10-20 cm) of the pasture, according to the levels of DMR. The pasture density (g of DM/m3) in superior and inferior strata had a positive relation with the DMR levels and negative when associated to the period (days) of the experiment. Dead material (DM) percentage was higher in the inferior stratum than green stem (GC)and green leaves (GL) percentages. In the superior stratum, DM and GL had a greater participation, however the GL increased while DM levels increased as well. |

Pers), em quatro níveis de resíduo de matéria seca (RMS: 1.978, 2.130, 2.545 e 3.857 kg de MS/ha), com lotação contínua e carga animal variável, as densidades e participação dos componentes botânicos. O delineamento experimental utilizado foi inteiramente casualizado, com duas repetições. As avaliações da densidade de forragem, participação dos componentes botânicos e a relação folha/colmo foram estudados nos estratos inferiores (0 - 10 cm) e superiores (10 - 20 cm) da pastagem, em função dos níveis RMS. A densidade da pastagem (g de MS/m3) nos estratos inferior e superior teve uma relação positiva com os níveis de RMS e negativa em relação ao tempo (dias) do experimento. A percentagem de material morto (MM) foi superior no estrato inferior em relação à percentagem de colmos verdes (CV) e de folhas verdes (FV). No estrato superior o MM e CV tiveram a maior participação, porém FV, aumentou à medida que se elevaram os níveis de RMS.Editora da Universidade Estadual de Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/322610.4025/actascianimsci.v22i0.3226Acta Scientiarum.
