Absence of fatty livers in rhesus monkeys fed orotic acid.

Pairs of rhesus monkeys were fed for 10 wk a basal diet containing 1% orotic acid or 10% nonfat milk powders. Amounts of total lipids in the liver and hepatic morphology were normal after 10 wk indicating that orotic acid in the diet did not induce fatty livers in rhesus monkeys.
