Values represent means ± standard errors. Pairwise comparisons using an unpaired, one-sided Student t test (P < 0.05, n = 3 per group) are indicated. 

^*C− different from sow-fed group. C+ group was not statistically significantly different from sow-fed group (P > 0.10). 

^† Statistically different at 0.05 < P < 0.10. C−, control diet without 20:4n−6 and 22:6n−3; C+, control diet with added 20:4n−6 and 22:6n−3. 18:3n−3 NAE was not detected and was omitted. 

^‡ C− different from C+.
