The basal diet contained 74.4% steam-flaked corn and 5% supplemental fat. There were no treatment effects (p>0.10) on site and extent of OM, starch, N, lipid and ADF digestion, nor on ruminal VFA molar concentrations. Post-ruminal lipid digestion averaged 69.3%, in close agreement with expected (71%; where fat digestion, % = 83.18-4.52FI-0.68FI3) based on level of fat intake (FI, g kg 1 of body weight).} }
