The aim of this study was to determine the efficacy of polyphenols in pigs. The experiment was performed on 52 sows divided into 4 groups. Untreated control sows (group 1) were not administered vitamin E in the premixes. The diets of the experimental animals were supplemented with vitamin E in the amount of 50 mg (group 2) or 100 mg/kg diets (group 3) (gestation diets) and 75 mg (group 2) or 150 mg/kg diets (group 3) (lactation diets). The diets of group four sows were supplemented with vitamin E (50/75 mg/kg, gestation/lactation) and Proviox (polyphenols) (50/75 mg/kg, gestation/lactation). The influence of different dietary inclusion levels of vitamin E and vitamin E/polyphenols on the performance, vitamin E concentrations, and antioxidant status of sows and piglets was analysed. The sows whose diets were supplemented with vitamin E and polyphenols (50:50) were characterised by similar fertility, mating success, and litter performance as the group whose diets were supplemented with vitamin E only. The results of this study indicate that sows receiving vitamin E and polyphenols and their progeny were characterised by similar or improved vitamin E status and improved antioxidant status compared with the animals whose diets were supplemented with 100 mg/150 mg of vitamin E/kg diet. It can be concluded that the replacement of 50% of dietary vitamin E with polyphenols did not compromise the growth performance of sows or piglets and improved their antioxidant status.
