註釋
Symptoms were identified in channel catfish fed diets deficient in the water-soluble vitamins pyridoxine, pantothenic acid. riboflavin, thiamine, folic acid, nicotinic acid, B-12, or Choline. Fat-soluble vitamin A and vitamin K deficiency systems were observed after feeding diets which contained beta-carotene and 4.0 milligrams of menadione (synthetic vitamin K) per 100 grams of food (dry weight). These deficiencies were eliminated by substituting vitamin A palmitate for beta-carotene and doubling the content of menadione. No dietary need was observed for the water-soluble vitamins biotin, inositol, ascorbic acid, and para-aminobenzoic acid.
