Abstract
high quality, since it showed the highest digestibility percentage (74.71) and higher protein values (21.52 %) and energy content (10.26 Mj/kg DM) with respect to the rest of the species. It was followed by Trichantera gigantea, with a digestibility percentage of 68.99; protein values of 20.34 % and energy content of 9.63 ME (Mj/kg DM). The Hibiscus rosa-sinensis species showed the lowest values of NDF (34.47 %) and ADF (17.13 %) and higher total starch content (3.31 %). In the mineral composition,
the values of Zn and Cu for the tree Trichantera gigantea and the amount of Ca and P for Tithonia diversifolia were higher than the other forage plants. According to the characterization of the shrubs, it is concluded that the species Piptocoma discolor, Trichantera gigantea and Hibiscus rosa – sinensi have an adequate content of protein, energy and digestibility. The species Tithonia diversifolia, Clitoria fairchildiana, and Solanum rugosum have an appropriate mineral content and a moderate content of secondary metabolites. All have acceptable levels of nutritional components that make possible their use in animal feeding.
Key words: silvopastoral, bromatological, Amazonia.
