[Mechanism of action of lysine in relation to its form of supply in swine].
It was the aim of this study to check the maximum value of lysine efficiency in feed proteins used as yet for the ascertainment of amino acid efficiency coefficients (cf. Liebert and Gebhardt 1988 b). For this purpose N balance measurements were carried out with 5 female pigs (30-35 kg LW) under conditions of continuous lysine infusion (duration of infusion 12 hours) through subclavian indwelling catheters with the help of a proven N utilization model. Based on defined limiting relations in the wheat/wheat gluten ration used, the lysine efficiency coefficient for infused lysine could be ascertained according to the difference method as 1.03, i.e., slightly above the maximum value for lysine efficiency determined up to now. The current standard of maximum lysine efficiency was determined as bc-1 Lys = 102, which is the basis of further calculations of lysine efficiency coefficients.
