Sixteen oligidic diets were prepared by mixing commercially available feed components in varying proportions to obtain different levels of protein and carbohydrate. Four diets with protein levels between 20% and 30% and carbohydrate between 32% and 47% gave the most satisfactory growth and development based upon survival, growth index, mean weight gain, conversion, and uniformity of growth. Additional notes are included on the effects of diet on wing length and tolerance to chemical intoxication.
