Flies were reared on standard food with 0.5% water (as blank), 0.5% CLA, or 0.5% safflower oil (as LA control) for 5 days. The values (% of total fatty acids) were measured by GC-MS and expressed as means±SE (n=3).
Desaturation indices were calculated by sum of C16:1 and C18:1 over sum of C16:0 and C18:0.
Means with different letters are significantly different (p<0.05) in each row.
CLA, conjugated linoleic acid; LA, linoleic acid; ND, not detected.
