Extract

The chemical determination of tannins has become inefficient to predict the negative effects in nutritional parameters. Apparently, different tannins have distinct activity (or reactivity) resulting in anti nutritional effects. The objective of this work was to test three compounds to establish a curve of biological equivalent effect of tannins using the in vitro gas production technique.
