¹The experimental diets were fed in three phases: days 0 to 29, days 29 to 47, and days 47 to 82.

²DDGS = distillers dried grains with solubles; one lot used for entire experiment.

³Enogen Feed Corn (Syngenta Seeds, LLC, Downers Grove, IL) or conventional (yellow dent corn); one lot of each variety used for entire experiment.

⁴HiPhos 2700 (DSM Nutritional Products, Inc., Parsippany, NJ) providing 891 phytase units (FTU)/kg and an estimated release of 0.08% available P.

⁵SID = standardized ileal digestible.

⁶STTD P = standardized total tract digestible phosphorus.
