[The effect of methionine, added to the diet of the gravid hen or injected into the egg, on the embryonic and post-natal development of the chick].
Chicks from hens consuming a methionine deficient diet have a live weight which is significantly reduced from hatching until 8 weeks of age. Normal growth rate was restored either by methionine supplementation of the hens diet or by injection of 0.5 mg of DL or L methionine. Injection of the D isomer alone was inactive.
