Dietary chloride requirement of broiler chicks fed on a wheat-soya bean diet

1. A diet based on soybean meal and wheat contained insufficient chloride to support normal growth in chicks. 2. Ammonium chloride and sodium chloride were equally good sources of supplementary chloride for the chick. 3. When seven diets providing increasing proportions of chloride from 608 to 1808 mg/kg, were fed to chicks, maximal growth at 21 d was obtained at about 1200 mg chloride/kg diet.
