Abstract: In order to study the effects of leaves and seeds of S.album on growth performance and antioxidant function of Wenchang chickens. 180 70-day-old Wenchang chickens were randomly allocated to 4 groups. Each group had 3 replicates and 15 chickens per replicate. The control group was fed with the basal diet, test groups 1, 2 and 3 were fed basal diets containing 8% fermented leaves and 1% seeds, 4% leaves and 1% seeds, 3% leaves and 2% seeds of S.album respectively. The results showed that leaves and seeds of S.album supplementation significantly increased serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) activity of Wenchang chickens (P<0.05), but no evident effect on performance was observed(P>0.05). The result implied that leaves and seeds of S.album supplementation in diets could improve the antioxidant function of Wenchang chickens, and add the quantity was positive correlation.

Key words: leaves and seeds of S.album; Wenchang chicken; antioxidant function; growth performance
