∑SFA: sum of saturated fatty acids; ∑UFA: sum of unsaturated fatty acids; ∑MUFA: sum of monounsaturated fatty acids; ∑PUFA: sum of polyunsaturated fatty acids. Different letters within the same row corresponding to the same diet group indicate significant differences (). Different numbers within the same row corresponding to the same sampling point indicate significant differences (), when the three finishing diets are compared.
