Extract

Phenolic compounds, mainly tannins, depress the nutritive value of many feedstuffs. Tannins are hydrosoluble polymers which form complexes, essentially with proteins. These complexes are broken under conditions of high acidity (pH <3.5) or high alkalinity (pH =7.5). The aim of this work was to investigate the effects of different treatments on chemical composition and tannin bioassay of tanniniferous plants from the Northeast of Brazil.
