Dietary brown seaweed and plant polyphenols in hyperprolific sows: Productive performance, blood parameters and antioxidant status

This study evaluated the productive performance, blood parameters and antioxidant status of hyperprolific sows fed control diet or supplemented with brown seaweed polyphenol mixture (SPM). Ninety-six farrowing highly prolific (Topigs 20) were assigned to two dietary treatments from day 107 ± 2 days gestation until weaning: same containing 15 g/day SPM. Sows SPM tended have lower backfat losses (P = 0.06) than sows. No difference was observed in daily feed intake. litter birth weight number piglets per observed.
