Alternanthera filoxeroides. Cuts and determination nutritional value samples made. results following values: for dry matter 36.6%, crude protein 9.24%, neutral detergent fiber 67.9%, acid (ADF) 40.6%. Digestibility estimated based on ADF resulted an average 57.3%. Values total polyphenols relatively low, ranging between 2.77 0.83%, being 1.99%.
