Dietary treatments: Treatment 1-Contro l = 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, tibial bone and blood samples were collected for analysis using IACUC-approved methods. Tibia bone strength was measured in terms of bending moment (kg/m²) and peak force (kg) and was not different between treatment diets (P < 0.05).

^ab

Means within the same column lacking a common superscript differ significantly (P < 0.05). Blood parameters measured: HCO₃ = bicarbonate, pCO₂ = partial pressure of carbon dioxide, TCO₂ = total carbon dioxide, iCa²⁺ = ionized calcium.
