Abstrakt: Encephalomalacia was induced in chickens more than 64 days old by feeding a high linoleic acid diet with an antioxidant (ethoxyquin) for 64 days and then deleting the antioxidant. The cerebella of young chickens fed linoleic acid contained greater proportions of linoleic acid, arachidonic acid, and fatty acids with retention times corresponding to C-22 polyunsaturated fatty acids than chickens fed low linoleic acid diets. The cerebella of chickens with encephalomalacia were higher in linoleic acid and an unknown acid than the cerebella from control chickens fed antioxidant. Other fatty acids were not significantly affected by the disease. The cerebella of hens fed a high linoleic acid diet for 12 weeks, starting from 500 days old, contained a higher proportion of linoleic acid and C-20 triene than hens fed a low linoleic acid diet. In contrast to chicks, the % of arachidonic acid or fatty acids with retention times greater than arachidonic were not affected by diet.
