“…The results obtained in experiment I are summarized in Table II However, the recovery percentages of 14C derived from methionine-methyl-14C were 4.33, 5.33, and 9.99% of the dose, respectively, which were 101, 94, and 90% of the corresponding values calculated from the equation obtained on the methionine diets without cystine in experiment 1-1.…”

Methionine requirements of male White Leghorn chickens were estimated at 5 stages of growth by growth and the recovery of 14C in respiratory carbon dioxide. The methionine requirement for maximumdaily gain decreased with increasing age according to the equation; logY=-0.000243X-3.22, where Y and X represent the methionine requirement as percentage of the diet and g of average body weight of the chickens during the experimental periods that achieved maximum daily gain. The recovery percentage of 14C derived from methionine-1-14C remained low, and then increased rapidly. The methionine requirement found from the recovery of 14C also decreased with increasing dietary methionine levels according to the equation; log Y=-0.000216X-3.02, where Y and X represent the methionine requirement as percentages of the diet and g of body weights of chickens at the beginning of the recovery test for 14C Dietary cystine spared the methionine requirement for growth, but did not affect the recovery of 14C in the respiratory carbon dioxide.

“…Kosaka et a/. 5 ) reported that no difference in the requirement of sulfur-containing amino acids was found between 2 meat-type and egg-type chick breeds. However, it has to be born in mind that the maximum daily gains obtained on the experimental amino acid diets were about 5% lower than those on the stock diet containing 20% crude protein.…”
