Effects of β-alanine on jejunum antioxidant enzyme activity of weaned piglets.

Item	β-alanine addition level1, mg/kg				SEM2	P-value
	0	300	600	1,200
T-AOC, U/mgprot	0.17	0.17	0.20	0.19	0.01	0.419
SOD, U/mgprot	3.73b	3.76b	4.65a	3.48b	0.15	0.020
MDA, nmol/mgprot	0.27	0.09	0.05	0.08	0.03	0.095
GSH-PX, mol/L	16.01	7.81	6.79	7.46	1.48	0.126

T-AOC = total antioxidant capacity; SOD = superoxide dismutase; MDA = malondialdehyde; GSH-PX = glutathione peroxidase.

^a,b Different superscript letters in the same row indicate significant differences (P < 0.05).

¹Diets supplemented with 0, 300, 600, and 1,200 mg/kg levels, respectively.

²SEM = standard error of the mean.
