¹Treatment diet samples were collected at the feed mill after manufacturing.

²SID = Standardized ileal digestible; Low (50% SID Val:Lys) and high (85% SID Val:Lys) diets were blended at the feed mill to create the intermediate treatments.

³Composite samples were submitted to Ward Laboratories (Kearney, NE) for analysis.

⁴Composite samples were submitted to Ajinomoto Heartland Inc. (Chicago, IL) for AA analysis.
