Experiments were carried out to determine the effect of mixing concentrates and corn (Zea mays L.) soilage with sesbania rostrata (Sesbania rostrata) on chemical composition and fermentative quality silages. In experiment 1, concentrates (brown rice, beet pulp, wheat bran or flaked corn) was added to sesbania at 15% on fresh matter basis. In experiment 2, sesbania was ensiled with corn soilage at the rates of 0, 25, 50, 75 and 100% on fresh matter basis. The addition of concentrates improved the silage quality by increasing lactic acid content and reducings the pH value and acetic acid content. In vitro dry matter digestibility (IVDMD) was the highest in silages mixed with wheat bran and followed by those mixed with brown rice, flaked corn and beetpulp. The contents of crude protein, organic cell wall and acid detergent fiber decreased and IVDMD increased with increasing the ratio of corn soilage to sesbania. The pH value, acetic acid content and volatile basic nitrogen as a percentage of total nitrogen (VBN/TN%) decreased and lactic acid content increased with increasing the ratio of corn soilage. From the above, it was concluded that sesbania should be mixed with concentrates or witn corn soilage to make good quality silage from It
