Abstract
Three experiments were conducted to determine the biological potencies of eight lysine analogues in diets of young turkeys. Diets containing increasing levels of added L-lysine or a lysine analogue were fed to 9-day-old male poults for periods of 12 or 14 days. Multiple regression analyses of body weight gains on levels of supplemental L-lysine or analogue were computed. Relative potencies of the lysine analogues were calculated using the slope-ratio technique. Relative potencies of 6-N-N-dimethylamino-2-hydroxyhexan-N,N-dimethylamide, 6-N-acetylamino-2-hydroxyhexanamide, 6-N-propionylamino-2-hydroxyhexanamide. 6-N-butyrylamino-2-hydroxyhexanamide, 6-N-methylamino-2-hydroxyhexan-N-methylamide and alpha-keto-epsilon-acetylamino-caproic acid were not significantly different from 0%. Mono-hydroxymethyl-L-lysine-calcium and bis-hydroxymethyl-L-lysine-calcium had relative potencies of 62 +/- 6 and 52 +/- 7%, respectively, on a molar basis.
