Abbreviations: TAG, triacylglycerols; DAG, diacylglycerols; MAG, monoacylglycerols; FFA, free fatty acids. ¹ Lipid class concentration (mg/g)/Ti concentration (mg/g) in each intestinal segment and excreta. ² Values are pooled means of 6 replicates with 12 chickens/replicate fed diets supplemented with 6% of palm oil (P), soybean acid oil (SA), soybean oil (S), or oil blends with 4% palm oil + 2% soybean acid oil (P4-SA2) or 2% palm oil + 4% soybean acid oil (P2-SA4). ³ SEM = standard error of the mean. ^a–d: means in a row not sharing a common letter are significantly different (p < 0.05).
