Abstract
THE wide range of folic acid requirements of chickens reported by various authors1 is partly explained by considerations of dietary and genetic factors known to affect requirements. Excess intake of choline2 and glycine3 has been shown to depress growth or produce anæmias which can be prevented by feeding supplementary folic acid. In experiments at this Station, the effect of choline on folic acid requirements has been confirmed, and supplementary methionine has been shown to have a similar effect.
