Apparent metabolizable energy (AME) calculated for adult broilers according to Wiseman’s equation [28] and by applying the MIU (g/100 g) correction to it [32] of (a) acid oils from chemical refining (n = 79) and (b) fatty acid distillates from physical refining (n = 13). See Table 1 for botanical group abbreviations. Within each type of refining and variable, botanical groups bearing different letters (a–d) are significantly different according to Kruskal–Wallis test and post-hoc comparisons (p ≤ 0.05).
