For each line, values with different letters (a–c) showed significant differences between the three dietary groups in the unstressed condition (ANOVA followed by MCP, p<0.01).
1
Values are means ± SEM (g/100 g of total fatty acids; n = 6 per group).
2
FA, fatty acids; 20:4n-6: arachidonic acid (AA); 22:5n-6: docosapentaenoic acid (DPA); 22:6n-3: docosahexaenoic acid (DHA); DEF, Deficient diet; CON, Control diet; ENR, Enriched diet.
