Abbreviations: AME, apparent metabolizable energy; TFA, total fatty acids; SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids. 1 Values are pooled means of 6 replicates from chickens 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). 2 Values are pooled means of 6 replicates with 16 chickens/replicate. 3 Values are pooled means of 6 replicates with 12 chickens/replicate. 4 SEM = standard error of the mean. a–d: means in a row not sharing a common letter are significantly different (p < 0.05).
