Fatty acid content in fishmeal, salmon filet and beef. Gas chromatography determination of individual fatty acid (FA) content in freeze-dried fishmeal, salmon filet and beef used to supplement the different HFDs. In total, 11 saturated FAs (SFA), 6 monounsaturated FAs (MUFA), 10 polyunsaturated FAs (PUFA) and 5–8% uncharacterized FAs (not shown) were detected. Ingredients were measured in in triplicate. Analytical variation was ~ 2% for abundant FAs and maximum 7% for rare FAs. a Fatty acid (FA) composition of SFA, MUFA and PUFA expressed as % of total FA content. b–d Concentrations of the most abundant SFAs, MUFAs and PUFAs expressed as grams of FAs per 100 g of freeze-dried protein extract (n = 3)
