- 1. 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.
- 2. 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.
- 3. 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.
