Utilization of a Delayed Lysine Supplement by Young Rats

Abstract
Experiments were conducted to determine the utilization by young rats of the delayed lysine supplement administered by stomach tube or incorporated in an otherwise adequate but protein-free basal diet. Data obtained indicate that young rats can synthesize protein when fed an otherwise adequate diet containing proteins deficient in lysine, for 12 hours, and then, in the next 12 hours, fed a protein-free basal diet and a single daily dose of lysine given by stomach tube, or the same basal diet supplemented with lysine.
