*The same symbol in the superscript indicates statistically significant differences (P ≤ 0.05) for the type of fat.

_abcStatistically significant differences (P ≤ 0.05) for the emu age were marked with different letters in the subscript.

^abcStatistically significant differences (P ≤ 0.05) for interaction type of fat × age of emu were marked with different letters in the upper index.
