Values were presented as mean ± SEM (n=32) of endogenous fatty acids from the animals over the entire experimental period.

SFA: saturated, MUFA: monounsaturated, PUFA: polyunsaturated, HUFA: highly unsaturated fatty acids.

Significant differences were determined by two-tailed, paired t-test with P values of 0.05*, 0.01**, 0.001 or lower ***.
