Molybdenum requirements of chickens.

1. The requirements of all classes of chickens for molybdenum are 0.03 mg/kg diet or less. 2. Dietary sulphate and tungstate both reduce the availability of dietary molybdate. 3. No evidence was obtained that either the clubbed down, ginger hair syndrome in chicks or the scabby hip syndrome in broilers is due to a simple molybdenum deficiency.
