¹Diets were fed in 2 phases from days 0 to 7 and days 7 to 21, for phases 1 and 2, respectively.

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

³CWB was included in the diet at 4% from days 0 to 21.
