Composição bromatológica de espécies herbáceas da Caatinga


The objective of this work was to evaluate the chemical composition of the pool and of four species of caatinga herbaceous vegetation in the rainy and dry seasons. The experiment was conducted in three selected shrub areas at different levels of conservation. Four samples of each species (Arachis pintoi, Boerhavia diffusa, Heliotropium ternatum, Aristida adscensionis) were collected in each area and from a pool of species for determination of bromatologic composition. In the dry season, only the pool of species and the grass Aristida adscensionis were evaluated. There was a significant effect of the studied area on the chemical composition of all analyzed species. The nutrient content found in the dry matter (DM) and the digestibility of the pool of species indicate that caatinga herbs presented improved quality in the rainy season. The qualitative variables of the studied species were most heterogeneous due to the variability found in caatinga. Conservation conditions in caatinga and season of the year influence bromatologic composition of the species Arachis pintoi, Boerhavia diffusa L., Heliotropium ternatum Vahl. Aristida adscensionis L. and of a pool of typical species found in Caatinga.
