Abstract: | The availability of lysine from Torula yeast has been measured with chicks and rats on the basis of growth response, feed or protein efficiency, nitrogen retention (chicks), and lysine absorption (rats). Consistently greater growth responses were obtained on lysine-deficient diets supplemented with 15–20% Torula yeast than could be accounted for on the basis of the lysine so provided. Measurements involving weight gains, therefore, did not prove to be adequate criteria for evaluating lysine availability. On the other hand, nitrogen retention data disclosed that yeast lysine was about 75% as available to the chick as the synthetic substance. With rats, yeast lysine was about 90% as efficiently absorbed as the synthetic amino acid. |
