Effects of dietary GSP supplementation on the antioxidant status in serum of sow

Items1 (n = 8)	CON2	200VE2	200GSP2	300GSP2	SEM	P
T-AOC, IU/mL	29.14	26.83	32.14	41.43	4.37	0.700
SOD, IU/mL	37.51b	42.08b	61.81a	66.21a	3.26	<0.001
GSH-Px, IU/mL	417.83b	586.30a	562.24a	620.33a	23.71	0.002
MDA, nmol/mL	4.13	2.94	2.56	2.33	0.37	0.339

^a,bMeans values within a row with different letters superscripts means significantly different (P < 0.05).

¹T-AOC = total antioxidant capacity; SOD = superoxide dismutase; GSH-Px = glutathione peroxidase; GSH = glutathione; MDA = malonaldehyde.

²GSP = grape seed polyphenols; CON = basal diet; 200VE = basal diet + 200 IU/kg vitamin E; 200GSP = basal diet + 200 mg/kg GSP; 300GSP = basal diet + 300 mg/kg GSP.
