Abbreviations: AME, apparent metabolizable energy; TFA, total fatty acids; SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids. ¹ 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). ² Values are pooled means of 6 replicates with 4 chickens/replicate. ³ Values are pooled means of 6 replicates with 2 chickens/replicate. ⁴ SEM = standard error of the mean. ^a–c: means in a row not sharing a common letter are significantly different (p < 0.05).
