The effect of dietary lysine levels on performance and meat yields of White Pekin ducks. 1983

R L Adams, and P Y Hester, and W J Stadelman

Four trials were conducted to determine the effects of dietary lysine levels ranging from .70 to 1.00% on performance and yield of different carcass components of male and female White Pekin ducks. Dietary lysine had no significant effect on weights or feed efficiencies at market age of 48 or 49 days; however, significant differences were obtained with yields of component parts for the males in Trial 2 and the females in Trial 3. In these trials, overall meat yields were significantly better for males fed levels of lysine between .80 and .95% and for females fed a lysine level of .90%.
