Extract

Some herbaceous browses have shown a dry tolerance and had been used as animal feed. However, some of those plants have anti nutritional compounds such as tannins that can interfere on intake and digestibility. Tannins are polyphenolic compounds originated from the secondary metabolism of the plant as protection against insects, birds and as a result of drought, temperature or soil fertility. The objectives of this work were to evaluate the level and variation of tannins in important browses from the semi-arid of Brazil and to investigate the effects of different treatments (oven-, shade- and sun-drying and treatment with urea) on phenolics compounds.
