 The undertaken study aimed at analysing the effect of linseed oil used in diets for turkey hens on contents of pro- and antioxidants in their tissues. Additionally, correlations were analysed between the contents of these compounds in blood, liver, and muscles of the birds. The experiment was conducted on 240 one-week-old turkey hens reared until 16 weeks of age, randomly allocated into two feeding groups. Hens from the first group received soybean oil in their complete feed mixture, whereas linseed oil was the source of fat for turkey hens from the second group. The oil content of the diet was on the level appropriate for the period of feeding: Starter - 0.5%; Grower I - 1.0%, Grower II - 2.5%; Finisher I - 3%. The redox parameters were assayed in breast and thigh muscles, blood, and liver. Introduction of PUFA n-3 high linseed oil to a feed mixture contributed to the enhancement of lipid peroxidation processes, which was indicated by a significant increase in concentrations of H2O2 and malondialdehyde in muscles, and by an increase of superoxide dismutase activity and concentrations of vitamin C and minerals (Cu+2, Zn+2, Fe+2, Se+2). This points out the need of strengthening the antioxidative defence by the use of suitable antioxidants. The use of linseed oil as a feed material for turkey hens additionally contributed to changes in parameters determining the ferric reducing ability of plasma (FRAP). The increased FRAP values resulted from a significant increase in vitamin E level.
