^aDry matter basis.

^bCalculated from weekly ingredient assays and batching records.

^cContainted 39% crude protein as nonprotein nitrogen on a dry matter basis and provided vitamins and minerals to meet nutrient requirements (NASEM, 2016).

^dContained 39% crude protein as nonprotein nitrogen and 648 mg/kg monensin (Rumensin 90; Elanco Animal Health, Greenfield, IN) on a dry matter basis and provided vitamins and minerals to meet nutrient requirements (NASEM, 2016).

^eContained 1665 mg/kg monensin (Rumensin 90; Elanco Animal Health).

^fNE_m, net energy for maintenance; NE_g, net energy for gain; calculated from tabular net energy values (Preston, 2016).
