Values represent means ± SD, n = 8 per diet. P < 0.05 indicates that all means are not equal; NS, not significant. Pairwise comparisons determined using Student’s t-test; means not sharing a common superscript are significantly different (P < 0.05).

ARA, arachidonic acid; DHA, docosahexaenoic acid.
