Control, diet 1, and diet 2 represent corn-soybean meal-based diets containing 0% microalgae (control), 2% microalgae (diet 1), and diet 1 + 100% more methionine.
Microalgae was supplied as DHA Natur (Archer Daniels Midland Company, Clinton, IA) which contained 9.8% CP and 16.57% DHA (as per product label).
SFA, saturated fatty acids (14.0 + 16.0 + 18:0); MUFA, monounsaturated fatty acids (16:1 + 18:1 + 20:1); total n-3 = 18:3 n-3+20:2 n-3+22:5 n-3+22:6 n-3.
Abbreviations: DHA, docosahexaenoic acid; FA, fatty acids.
