[Methionine supplementation in the diet of the pregnant rat. 2. Riboflavin metabolism and hepatic concentration of water, lipid and protein].

Dietary addition of methionine suppresses the liver lipidosis in gestating rat fed a diet containing 9% by weight of casein. Riboflavin metabolism is not affected by this addition neither in the dam nor in the newborn rat. Riboflavin content in liver increases in the dam along with the protein content of the diet but does not change in the newborn rat.
