Abstract
The effects of the addition of DL-methionine, L-lysine, L-threonine and L-tryptophan to casein on the formation of the fatty liver and on the growth of rats were investigated.
(1) The addition of 0.25% DL-methionine to 5% casein diet caused 50% fat deposition inthe liver. The addition of 0.25% DL-methionine-sulfoxide caused 23% fat deposition in theliver. The growth of the rats in the groups was good.
(2) The growth of the rats in the group with DL-methionine in casein diet was promotedby adding L-threonine and there appeared no fatty liver. This group showed the same result asthe groups with L-lysine-HCl, L-threonine and L-tryptophan.
(3) The formation of the fatty liver seemed to have no relation with the content of caseindiet.
