Abstract
The young albino rats were fed with wheat flour fortified with 0.5% of L-lysine, DLthreonine, DL-methionine or DL-tryptophan, respectively, and the effects on the growth rate, protein efficiency and biological value were studied. The positive effects on the growth rate and biological value were observed only with L-lysine.
When the diet was fortified by 0.5% of lysine plus0.5% of threonine, methionine or tryptophan, the effects on the growth rate and protein efficiency were observed only with lysine plus tryptophan.
