Increasing the methionine content of the diet from 0 to 0.3% resulted in an increase of diet intake by the dams which induced a decrease of their weight losses and a better growing of the pups. A threonine additional supplementation had no effect on these parameters. In the lactating rat, the neutral lipid content of liver increased with a 0.1% methionine supplementation of a low protein diet and reached a plateau with 0.3-0.4%. Moreover, a threonine deficiency and a steatosis was observed from the 0.1% methionine supplementation level. A threonine supplementation did not prevent the methionine induced modifications observed during lactation. This inefficiency of threonine concerned neutral lipid content as well as morphological alterations of liver.
