Extract

Brazil has arid regions where livestock production is limited by forage source. However, some native herbaceous legumes have a dry tolerance and had been used as animal feed. Some of those plants have anti nutritional compounds such as tannins that and can interfere on intake and digestibility of these plants. Tannins have a high affinity with proteins and could make these molecules unavailable for animal. Compounds as polyvinylpolypyrrolidone (PVPP) have been used on tannin studies, because it has more affinity with tannins than proteins. Based on that, it is possible to evaluate the nutritive potential of tanniniferous plants, using PVPP as an inhibitor of tannin effects. The aim of this work was to evaluate the effect of tannins on in vitro rumen fermentation.
