Studies on the Nutritional Requirements of the Rhesus Monkey

Abstract

Monkeys are unable to survive upon a purified diet containing sucrose, casein, salts, corn oil, and all eight readily available members of the B group of vitamins and vitamin C. The deficient monkeys show a loss in weight, anorexia, leucopenia, slight anemia, cachexia, and intercurrent infections, especially bacillary dysentery. Any one of three liver products, whole liver, liver extract, and solubilized liver residue when fed at a 3% level in the diet, supports good growth, maintains the normal blood picture and tends to prevent dysentery and other secondary infections.
