Despite extended dry seasons of 5-7 months, farmers are able to continue raising cattle and goats in the drought-prone areas of Batangas. This study was conducted to document the potentials of indigenous fodder trees in this traditionally livestock-growing province. Participatory Rural Appraisal (PRA) methods were used. Tree performance was evaluated as to herbage production and fodder quality. In the dry season, an estimated 70% of fodder comes from trees, 15% from crop residues, 10% from native grasses and 5% from vines and shrubs. Some better-off farmers are able to provide some concentrates. Of the 34 tree species identified, 28 are indigenous. Among these, farmers highly preferred "anabiong" (Trema orientalis), "binunga" (Macaranga tanarius) and "kalios" (Streblus asper) in terms of their perceptions on the species, feeding value, tree growth and regrowth characteristics and tree management. Of these most preferred species, regular cutting every three months showed that T. orientalis produced the highest amounts of 9.8 kg DM/tree/year leaf yield. Fodder quality was highest with 173, 384, 349, 68, and 104 g/kg DM crude protein, neutral detergent fiber, acid detergent fiber, silica and lignin. In vitro dry matter digestibility was 52.8%. Indigenous tree and shrubs provide good quality fodder that supplement low quality native grasses and crop residues during the critical dry months. This system may be promoted in other livestock areas with similar conditions
