¹In experiment 2 group 1 diets were fed from days 0 to 13, and in experiment 2 group 2, experimental diets were fed from days 0 to 13 and all pigs received the same common diet from days 13 to 27.

²Complete diet samples were taken at manufacture. Samples were stored at −20 °C until they were homogenized and subsampled. Duplicate samples per treatment were submitted for analysis to (Ward Laboratories, Inc., Kearney, NE).

³CP >18% is observed due to the nitrogen from the nonessential amino acids added to the diet.
