1SFC = steam-flaked corn; DDGS = dried corn distillers’ grains plus solubles; DM = dry matter; CP = crude protein; ADF = acid detergent fiber; NDF = neutral detergent fiber; ADICP = acid detergent insoluble crude protein; NDICP = neutral detergent insoluble crude protein; EE = ether extract; TDN = total digestible nutrients; NEm = net energy for maintenance; NEg = net energy for gain.
2Ingredients are reported on a DM basis and rations were adjusted to 75% DM with water, respectively.
3TDN calculated utilizing Weiss et al. (1992) model.
4NEm and NEg calculated from Galyean et al. (2016) and NASEM (2016).
