Abstract
Gross protein value and phosphorus availability of 4 kinds of yeast, which were produced by the four domestic companies and were used in the multi-generation feeding experiment, were estimated by biological assay procedures recommended by this laboratory in the previous papers. Total 833 chicks were used in the assays.<br>Gross protein values of four yeasts tested were between 44 and 66, when no amino acid was supplemented. However, those were surprisingly improved to be 89-103 by simply supplementing DL-methienine at the level of 0.9-1.3% to the air-dried yeast.<br>Phosphorus availability of the yeast was satisfactory, being close to 100, except that of Yeast C, which was 59% in average.<br>The results of the estimation of gross protein value and phosphorus availability as well as available energy reported in this and previous papers reveal that yeast grown on n-paraffin is good source of protein and phosphorus as well as energy for poultry, if adequate DL-methionine is supplemented.
