Effect of a high-oleic peanut diet on apparent protein ileal digestibility and metabolizable energy in laying hens. Three isonitrogenous experimental diets (approximately 18% crude protein) were fed to ninety-nine 57-wk-old laying hens with 33 laying hens per treatment with three replicates of 11 laying hens per replicate for 8 wk: Conventional corn and soybean diet (CON), high-oleic peanut + corn (HOPN), or control spiked with 2.6% oleic fatty acid oil (CON-OA). Each bar graph represents the average ± SEM. ^a,bBar graphs with differing superscript are significantly different (P < 0.05).
