TAG: triacylglycerol; HDL: high-density lipoprotein; VLDL: very-low-density lipoprotein; LDL: low-density lipoprotein; ALT: alanine aminotransferase; AST: aspartate aminotransferase. EOs mixture of mint, parsley, and carrot seed oils. EOs: birds fed a basal diet supplemented with 1.5 g/kg EOs; EOs + BPO0.25: birds fed a basal diet supplemented with 1.5 g/kg EOs plus 0.25 g/kg black pepper oil (BPO); EOs + BPO0.5: birds fed a basal diet supplemented with 1.5 g/kg EOs plus 0.25 g/kg black pepper oil (BPO); EOs + RSO0.25: birds fed a basal diet supplemented with 1.5 g/kg EOs plus 0.25 g/kg radish seed oil (RSO); EOs + RSO0.5: birds fed a basal diet supplemented with 1.5 g/kg EOs plus 0.5 g/kg radish seed oil (RSO). SEM: standard error of the mean; abcdef means with different superscripts within the same row differ significantly (p < 0.05).
