Resumo: The objective of this research was to select elephantgrass clones for grazing conditions. A randomized complete block design was used, with 16 treatments and four replications. Each plot had a total area of 25m2, with the presence of animals. The following parameters were determined: leaf blade accumulation rate (LBAR) above 40cm height and total, stem accumulation rate (SAR), total forage accumulation rate (TFAR), dry matter concentration (%DM), crude protein concentration (%CP) and, neutral detergent fiber (%NDF). The results showed significant difference (P<0.05) between clones and evaluation periods for LBAR above 40cm, total LBAR and TFAR, with mean values of 28.08, 41.62 and 49.18kg/ha/day, respectively. Crude protein and NDF differences (P<0.05) were also found between the clones for all the different parts of the analyzed plant. The forage lost presented a similar chemical composition to the leaf blades above 40cm and to the post-grazing residue. The clones CE-08-AD and Venezuela AD presented a high performance considering the evaluated parameters and may be considered as promising materials.

Em parcelas com 25m2, foram estudados a taxa de acúmulo de lâminas foliares (LF) e de colmos (C), teores de matéria seca (MS), proteína bruta (PB) e fibra em detergente neutro (FDN). Houve diferença significativa (p<0,05) entre clones e períodos de avaliação para produção de LF acima de 40cm, produção total de LF e produção total de forragem, com valores médios de 28,08; 41,62 e 49,18kg/ha/dia, respectivamente. Os teores de PB e FDN também foram diferentes (p<0,05) entre os clones em todas as frações da forragem. A fração perdas de forragem apresentou qualidade semelhante às frações LF acima de 40cm de altura de resíduo pós-pastejo. Os clones CE-08-AD e Venezuela AD destacaram-se para a maioria dos parâmetros avaliados, mostrando-se promissores.Editora da Universidade Estadual de Maringá2008-04-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/185810.4025/actascianimsci.v26i2.1858Acta Scientiarum.
