Nutritional Characteristics and Digestibility of Woody and Herbaceous Native Plants from Tropical Flooded Savannas Ecosystems
Native plants constitute an enormous source of nutrients for grazing animals, although their use has been limited due to the lack of knowledge about its properties.

| Summary: | Native plants constitute an enormous source of nutrients for grazing animals, although their use has been limited due to the lack of knowledge about its properties. The aim of this research was to evaluate the nutritional characteristics of native plants from flooded savannas ecosystem. Seven transects (290 km) were carried out through the montane forests, gallery forests and open savannah ecosystems. A total of 42 plant species were collected (22 arboreal, 13 shrubs, 5 climbing and 2 herb plants) and their nutritional composition and digestibility were evaluated. Data analysis included univariate and multivariate methods. Nutritional composition and digestibility varied among the groups of arboreal, shrub, climbing and herb species. At an individual level plants such as G. americana, C. cf minor‐grandiflora and M. nobilis, A.Jahnii, P. hispidium, I. carnea, S. reticulate, H. furcellatus, and C. erosa stood out by their protein, ash, and digestibility. At a group level, a mixed of 19 plants presented the highest digestibility, and the lowest fiber fraction constituted a promising forage alternative. Data variability was explained in the 47% by protein, ash, digestibility, and the different fiber fractions variables. Further studies related with the animal acceptability, performance and the presence of secondary metabolites are needed before being fully recommended. |
