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 soybean oil (S6), palm fatty acid distillate (PA6), palm oil (P6), or oil blends with 4% soybean oil and 2% palm fatty acid distillate (S4-PA2) or 2% soybean oil and 4% palm fatty acid distillate (S2-PA4). ³ SEM = standard error of the mean. a–d: means in a row not sharing a common letter are significantly different (p < 0.05).
