Item	Lipid source
	Palm oil	Poultry fat	Fish oil	Corn oil	Flaxseed oil
Energy utilization1, %
DEc/GEc	91.0	93.4	94.4	98.1	97.5
MEc/DEc	99.5	99.2	99.5	96.9	99.3
NEc/MEc	90.6	90.8	91.5	90.1	89.5
Energy value2, MJ/kg DM
GEm	39.54	39.43	39.33	39.69	39.36
DE	35.98	36.84	37.11	38.95	38.38

NE	32.42	33.21	33.77	34.00	34.12

¹GEc, DEc, MEc, and NEc were calculated according to the Eq. [6].

²GEm was measured using Isoperibol Calorimete; DE = GEm × DEc/GEc; ME = DE × MEc/DEc; NE = ME × NEc/MEc.
