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, , in SPS for sustainable livestock production. Chemical-bromatological analysis of fruits revealed a high crude protein content and non-structural carbohydrates (NSC). An in vivo assay with Dorper lambs showed that increasing levels of in diets had a linear effect on both neutral detergent fiber (NDF) and NSC intake, with reduced NDF digestibility. However, no significant effects were observed on dry matter, organic matter, or crude protein digestibility. Moreover, methane (CH) emissions decreased with increasing inclusion, with daily CH emissions being up to 39% lower in animals fed with compared to those without. Dendrometric characteristics of trees indicated an average height of 8.79 m and a canopy area of 92.04 m when in pasture, with an average fruit production of 56 kg per tree, allowing for the inclusion of 108 trees per hectare. The study highlights the potential of as a natural feed supplement for ruminants in SPS during the dry season, offering environmental and economic benefits. The integration of this native species into grazing systems can promote sustainable livestock production practices while contributing to the conservation of Brazilian biomes.

林牧系统（SPS）因其多种益处而受到认可，包括动物福利、生产性能、温室气体减排、饲料质量以及整体生态系统服务。然而，用于林牧系统的本土树木成分有限，导致外来物种的普遍使用。本研究旨在调查本土豆科树木在林牧系统中实现可持续畜牧生产的潜力。对[树木名称]果实的化学分析表明，其粗蛋白含量和非结构性碳水化合物（NSC）含量较高。对杜泊羔羊进行的体内试验表明，日粮中[树木名称]水平的增加对中性洗涤纤维（NDF）和NSC摄入量均有线性影响，同时NDF消化率降低。然而，在干物质、有机物或粗蛋白消化率方面未观察到显著影响。此外，随着[树木名称]添加量的增加，甲烷（CH₄）排放量减少，与未添加[树木名称]的动物相比，添加[树木名称]的动物每日CH₄排放量降低了39%。[树木名称]树木的测树学特征表明，在牧场中时平均树高为8.79米，树冠面积为92.04平方米，每棵树平均果实产量为56千克，每公顷可容纳108棵树。该研究强调了[树木名称]作为旱季林牧系统中反刍动物天然饲料补充剂的潜力，具有环境和经济效益。将这种本土物种纳入放牧系统可以促进可持续畜牧生产实践，同时有助于巴西生物群落的保护。
