Abstract

Mertz et al. (1949) demonstrated that lysine is essential in the nutrition of swine. Since then considerable research has been conducted to determine the level of lysine needed to promote optimum growth and feed conversion in swine. Recent investigations (Crum et al., 1964; Wallace et al., 1964; Jensen et al., 1965) have been designed to measure the physical and chemical changes in the animal body which may accompany observed differences in performance due to varying lysine and protein levels.
