1 Digestible energy predicted by [128]: DE, kcal/kg = [37.890 − (0.005 × FFA, g/kg of lipid) − 8.200e(−0.515 × UFA:SFA)]/0.004184. 2 Digestible energy predicted by [140]: DE, kcal/kg = [9.363 − (0.097 × FFA, %) − (0.016 × n-6:n-3 fatty acid ratio) − (1.240 × C20:0, %) − (5.054 × insoluble impurities, %) + (0.014 × C16:0, %)] × 1000.
