Four experimental isonitrogenous (18.5% crude protein) diets were formulated: Trmt1-Control = conventional diet containing solvent-extracted defatted soybean meal and corn; Trmt2-EENO = diet containing extruded-expelled defatted normal-oleic soybean meal and corn; Trmt3-FFNO = diet containing full-fat normal-oleic soybean meal and corn; Trmt4-FFHO = diet containing full-fat high-oleic soybean meal and corn
Average Daily Feed Consumption = amount of feed consumed per week by each treatment group divided by 7 days.
Feed conversion ratio (FCR) = total egg weights (in grams) for each treatment/g total feed consumed by that treatment group over the 3-week feeding trial.
Mean Hen House Egg Production = total number of eggs produced divided by total number of hens present over the 3-week feeding trial.
Mean Daily Egg Weight = average mass of the eggs produced per week by each treatment group divided by 7 days.
Means within the same column lacking a common superscript differ significantly (P < 0.05).
P-value = statistically significant differences are identified by P < 0.05 in analysis of variance (ANOVA).
