Dietary treatments: Treatment 1-Control = conventional diet containing solvent-extracted defatted soybean meal and corn; Treatment2 = diet containing extruded-expelled defatted normal-oleic soybean meal and corn; Treatment3 = diet containing full-fat normal-oleic soybean meal and corn; Treatment4 = diet containing full-fat high-oleic soybean meal and corn. Forty-eight White Shaver hens were individually housed and randomly assigned to one of four isocaloric, isonitrogenous dietary treatments (12 replicate cages/treatment). At termination, liver, fat pad, and Pectoralis major breast muscle samples (6 per treatment) were collected for chemical analysis.

Crude Fat content = g crude fat/g total sample weight × 100; Fatty acid content = g of fatty acid/g total lipid content × 100.

^⁎

P-value = statistically significant differences are identified by P < 0.05 in analysis of variance (ANOVA).

^a,b

Means within the same row lacking a common superscript differ significantly (P < 0.05).
