Chemical defense in birch: inhibition of digestibility in ruminants by phenolic extracts

Chemical defense in birch: inhibition of digestibility in ruminants by phenolic extracts

The biological activity of phenolic extracts originating from winter twigs of birch (Betula pendula Roth.) was measured using the ruminant in vitro method and the nylon bag technique. Different extracts were prepared by extraction with organic solvents, removing phenols of corresponding solubility....
