%X A pesquisa foi realizada nos Campos Experimentais de Itamb¨¦, Caruaru e Serra Talhada, pertencentes ¨¤ Empresa Pernambucana de Pesquisa Agropecu¨¢ria, e objetivou avaliar caracter¨ªsticas bromatol¨®gicas de esp¨¦cies arb¨®reas e arbustivas de pastagens. Para an¨¢lises bromatol¨®gicas foram coletadas, nas ¨¦pocas seca e chuvosa, amostras compostas de folhas e galhos com at¨¦ 5,0 cm de diametro de esp¨¦cies arb¨®reas e arbustivas presentes em ¨¢reas de pastagens. Os teores m¨¦dios de MS das plantas foram de 38,89%, 48,27% e 55,20% nos Munic¨ªpios de Itamb¨¦, Caruaru e Serra Talhada, respectivamente. Para PB, observou-se valores de 15,87%, 14,09% e 10,19%, respectivamente. Os valores de FDN e de FDA foram de 52,37% e 37,63%, 46,33% e 30,33%, 50,25% e 35,07%, respectivamente. As esp¨¦cies, independente do local, apresentaram melhor composi  o bromatol¨®gica no per¨ªodo chuvoso.Para utiliza  o de esp¨¦cies em sistemas silvipastoris, al¨¦m da avalia  o de caracter¨ªsticas qualitativas, devem-se considerar aspectos de facilidade de propaga  o, adapta  o ¨¤s condi  es edafoclim¨¢ticas, tipo de animal e objetivo do sistema de produ  o animal. The research was conducted at the Experimental Fields of Itamb¨¦, Caruaru and Serra Talhada, owned by the Agricultural Research Companyof Pernambuco (IPA). The aim was to analyze the chemical characteristics of tree and bush species grown on pasture land. In each Experimental Station, data was collected from a random sampling, during the dry and rainy seasons. Samples consisted of leaves and branches up to 5.0 cm of diameter. The average MS concentrations were 38.89, 48.27 and 55.20%. As for PB, the values observed were 15.87, 14.09 and 10.19%. The NFD and ADF concentrations were 52.37 and 37.63, 46.33 and 30.33, 50.25 and 35.07%, for Itamb¨¦, Caruaru and Serra Talhada, respectively. The studied species, independent of the region, presented better chemistry composition during the rainy season. Thus, for an adequate selection of species in silvopastoral systems, besides the evaluation of qualitative characteristics, other aspects should also be taken into consideration such as propagation,adaptation to the soil and climate conditions, animal type and objective of the animal system production.
