SD, standard deviation; FDR, false discovery rate; FA, fatty acid; LA, linoleic acid; GLA, gamma linolenic acid; DGLA, dihomogamma‐linolenic acid; AA, arachidonic acid; ALA, α‐linolenic acid; ETA, eicosatetraenoic acid; EPA, eicosapentaenoic acid; DPA, dipicolinic acid; DHA, docosahexaenoic acid. *Values are mean weights (%wt: total FA weight) ± SD, medians and twenty‐fifth and seventy‐fifth percentile range. Population differences for each specific FA were compared with Wilcoxon paired‐sample signed ranks tests, with samples matched to lactational stage. Significance values are q‐adjusted P‐values obtained using the FDR method to control for multiple comparisons. ^†24:1n‐9 and 22:4n‐6 did not always separate during analysis and are reported together.
