title: [Effect of truly digestible lysine on live weight gain in rats].
abstract: It is to be proved in model experiments with rats that calculations with true digestible amino acids are more exact than calculations with the gross amount of amino acids and therefore are advantageous. 7 resp. 6 rations were tested whose gross contents of lysin, methionine and cystin were balanced. Their content of actually digestible lysin differed, however. The results of the two test series show distinctly that the prediction resp. assessment of the animals' performance in dependence on the amino acid content of the rations is most safely based on the actually digestible amino acids.
