Experimental diets with various levels (0, 8.5, 17.0 and 25.5 g kg −1 diet) of a freeze‐dried tannin extract obtained from faba bean seeds were evaluated in a bioassay with rats. Faecal nitrogen excretion increased and true nitrogen digestibility decreased significantly ( P < 0.01) with the inclusion of tannins in the diet. In contrast, the biological value of nitrogen was apparently unaffected.
