  1. Only major Fatty acid methyl esters were presented; thus they do not add up to 100%. EPA (20:5n-3) were not detected (<0.01%, trace). Each parameter was presented as the mean ± SEM (n = 6). * p < 0.05, ** p < 0.01, significant difference compared to the n-3 Adq group at 3 weeks of age determined by Student’s t-test. Different letters indicate significant difference at p < 0.05 among all dietary groups after 3 weeks of age
