Influence of Thyroactive Iodocasein on Growth of Chicks

Abstract

Rhode Island Red chicks were raised to 12 weeks of age on diets containing from 0.025 to 0.2% of thyroactive iodocasein. Chicks receiving the lower levels, required less feed per gram of gain than did the controls. Those fed diets with 0.1 and 0.2 % thyroactive iodocasein gained more than the controls and were more fully feathered than either the controls or those receiving the lower levels. The thyroactive iodocasein-fed chicks utilized their feed more efficiently than the controls only during the periods when they were gaining at a more rapid rate.
