The results showed that supplying lysine coated with the polyoxylateⅣand hydrogenated vegetable tallow in the rumen could significantly improve the concentration of plasma free lysine in the jugular vein (11.18ug/ml)(P＜0.05), which is about 66.61% of that with duodenal infusions of lysine(16.97ug/ml). The concentrations of free lysine were 7.31ug/ml and 8.00ug/ml with the basal diets and supplementing of Lys in the rumen respectively.
