  1. EE Ether extract, AEE Acid-hydrolyzed ether extract, SFA Saturated fatty acid, UFA Unsaturated fatty acids
  2. a,b,c Least squares means within a column with different superscripts differ (P < 0.05)
  3. 1 Standardized ileal digestibility of fat and fatty acids were calculated by correcting the apparent ileal digestibility values with the basal endogenous losses. Basal endogenous losses (g/kg DMI) averaged 3.14 EE, 9.30 AEE, 0.70 C16:0, 0.22 C18:0, 0.25 C18:1, 0.41 C18:2, 1.15 SFA, 0.91 UFA
