The effect of polyphenols on the performance and antioxidant status of sows and piglets

Abstract

ABSRACTThe 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.

Phenolic compounds as natural feed additives in poultry and swine diets: a review

“…Lower serum MDA level in laying hens fed with thyme and rosemary dry leaf powder as source of phenolic compounds at 0.9% level was also reported [ 50 ]. The replacement of 50% dietary vitamin E with polyphenols did not alter the growth performance but could improve the antioxidant status of sows or their offspring [ 73 ]. In piglets, dietary supplementation of polyphenol mixture originated from apples, grape seeds, green tea leaves and olive leaves could reduce plasma MDA value [ 74 ].…”

Evaluation of Sugarcane-Derived Polyphenols on the Pre-Weaning and Post-Weaning Growth of Gilt Progeny

“…The comparatively poorer growth of GP during the pre-weaning period [3] can partially be attributed to the lower milk yield of the gilt [8,9], meaning that reducing oxidative stress in lactating gilts may be a useful management strategy for increasing productivity in GP. This was demonstrated by Lipiński et al [10], who observed antioxidant polyphenol supplementation improved litter and body weights at weaning. Polyphenols are secondary plant metabolites that exhibit anti-oxidative effects [11].…”

Dietary Plant Extracts Improve the Antioxidant Reserves in Weaned Piglets

“…The determination of the active compounds of U. tomentosa , T. parthenium and B. serrata was performed by the supplier (A.C.E.F. Fiorenzuola d’Arda, Italy) using high-performance liquid chromatography (HPLC) [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

“…Previous studies have reported that dietary plant polyphenols in piglets enhance blood antioxidant status [ 14 , 15 ]. However, some studies report no improvements in the markers related to antioxidant status due to supplementation with polyphenols [ 16 , 17 ].…”
