Abstract
3 N balance trials were carried out with pigs weighing 12-40 kgs to test values for the lysine requirements of pigs that had been obtained in feeding trials with rations containing varying levels of crude protein. The present trials used rations containing 17%, 15% and 13% crude protein; the corresponding lysine percentages were 0.89, 0,79 and 0.62. The N balances revealed significant differences between the three crude protein levels amounting to 1.50 g, 1.36 g and 1.05 g per kg liveweight 0,67.
