Abstract
ANTIBIOTICS and 3-nitro-4-hydroxyphenylarsonic acid have been reported by various workers to stimulate the growth of chicks when added to their rations in low concentrations. Most of these experiments covered only the first four to twelve weeks of life, and male chicks were generally used. In short-term experiments, the addition of aureomycin to the ration of growing pullets enhanced the response of serum calcium and serum riboflavin to injected œstrogens, and it was suggested that the response of endogenous œstrogens might be similarly affected1.
