Emergence orders and growth rates in the juvenile plumages of the Brown Leghorn

Uptake of S35 in the Feathers, Gizzard Lining, Liver and Muscle of Young Chickens After Injection with Radioactive Methionine or Sulfate

“…This is suggested by the observations of Briggs and Spivey (1953) and Gordon (1953), that growth responses are often obtained in young chickens by supplementation of diets deficient in cystine and methionine with sodium sulfate or sulfur. At the time of injection of methionine*, the lowered numbered feathers were not growing rapidly, whereas the higher numbered feathers were still in a rapid phase of their growth (Juhn, 1938). The nutritional significance of inorganic sulfur compounds will await future experimentation.…”
