The Effect of Different Carbohydrates and Antibiotics on the Growth of Chicks and the Storage of Vitamins

Abstract

Chicks fed rations supposedly adequate in all the known vitamins and containing lactose as the carbohydrate had a high concentration of folic acid and C.F. in their livers as compared to chicks fed other carbohydrates. The type of carbohydrate fed chicks receiving adequate amounts of all the known vitamins does not affect the level of several of the water-soluble vitamins found in the livers or ceca in a way which would explain the superior growth obtained on a dextrin ration. The effect of antibiotics on the growth of chicks receiving adequate amounts of all the known vitamins is variable and the concentrations of several of the water-soluble vitamins found in the chick livers cannot be correlated with the growth responses.
