Assessing the impact of <i>Samanea tubulosa</i> trees on methane emissions and its potential as a feed supplement for ruminants in silvopastoral systems.

ABSTRACT: Silvopastoral systems (SPS) have been recognized for their multiple benefits, including animal welfare, performance, greenhouse gas mitigation, forage quality, and overall ecosystem services. However, the availability of native tree components for SPS is limited, leading to the prevalent use of exotic species. This study aimed to investigate the potential of the native leguminous tree, Samanea tubulosa, in SPS for sustainable livestock production. Chemical-bromatological analysis of S. tubulosa fruits revealed a high crude protein content and non-structural carbohydrates (NSC). An in vivo assay with Dorper lambs showed that increasing levels of S. tubulosa in diets had a linear effect on both neutral detergent fiber (NDF) and NSC intake, with reduced NDF digestibility.
