Extract

Animal production in Brazilian semi-arid north-east is limited by dry-season feed shortage leading to high mortality and low production of the herds. Most of vegetation consists of forage plants with high protein content but low digestibility and high levels of tannins (10%). The aim of this work was to investigate the biological activity of tannins using the in vitro gas method with the addition of polyethylene glycol (PEG).
