Kansas Agricultural Experiment Station Research Reports
One-hundred fifty pigs weaned at 14 ± 2 days of age and averaging 9.8 ± 2.8 lb were used to determine the effects of increasing levels of dietary lysine on pig performance. Pigs were fed a pelleted corn-soybean meal diet (1.10% lysine) containing 20% dried skim milk and 14.4 % lactose or diets containing 1.25, 1.40, 1.55, or 1.70% lysine provided by L-lysine HCI. Average daily gain (ADG), feed conversion (F/G), and plasma urea concentrations were determined on day 7, 14, and 21 of the experiment. On day 7, ADG increased linearly (P<.05) with increasing lysine level. By day 21, ADG was increased 12% (linear and quadratic P<.15) for those pigs fed the 1.40% lysine diet. On day 7, 14, and 21, F/G improved (linear and quadratic P<.02) and plasma urea concentrations decreased (linear, quadratic, and cubic P<.O 1) as lysine level increased. Feed intake was not affected by dietary treatment (P>.20). At the end of the 21 …
