Fatty acids are expressed as percent of crude fat. Diets are also analyzed for C14:1, C15:0, C20:5, C22:5, and C22:6, but these fatty acids are not detected in any diets.

1ND = not detected.

2Total SFA = C10:0 + C12:0 + C14:0 + C15:0 + C16:0 + C17:0 + C18:0 + C20:0 + C22:0.

3Total MUFA = C14:1 + C16:1 + C17:1 + C18:1 + C20:1 + C22:1.

4Total PUFA = C18:2 + C18:3 + C20:2 + C20:3 +C20:4 + C20:3 + C22:4 + C22:5 + C22:6.

5Iodine value = [(C16:1) × 0.95] + [(C18:1) × 0.86] + [(C18:2) × 1.732] + [(C18:3) × 2.616] + [(C20:1 × 0.785] + [(C22:1) × 0.723], where values in parentheses indicate concentrations of the specific fatty acids as a percentage of crude fat (AOCS, 1998).
