Amino acid supplementation of low protein turkey starting rations.
Turkey poults fed rations containing 22.1% protein had a much slower rate of growth when compared with poults receiving a ration containing 29.8% protein. Methionine supplementation had no effect on body weight and mortality to 18 days of age. Supplementation of the 22.1% protein diet with lysine (0.2%) significantly improved growth rate over the unsupplemented 22.1% protein diet. The addition of methionine to the 22.1% protein diet supplemented with lysine (0.2%) produced slight additional response in body weight; however the drop in mortality was much more dramatic as increments of methionine were added to the 22.1% protein diet supplemented with lysine (0.2%).
