1IgA = immunoglobulin A; IgG = immunoglobulin G; IL-2 = interleukin 2; C3 = complement 3; GSH-Px = glutathione peroxidase; T-SOD = total superoxide dismutase; T-AOC = total antioxidant capacity; MDA = malondialdehyde; NO = nitric oxide; TNOS = total nitric oxide synthase; iNOS = inducible nitric oxide synthase; cNOS = constitutive nitric oxide synthase.
2Sheep were fed 0%, 1.2%, 1.6%, and 2.0% mannan-oligosaccharides (MOS) (n = 3 per treatment). Mean results of immune and antioxidant parameters are shown for collection at seventh day of the study for each treatment.
3SEM: standard error of the mean.
a,b,cMeans within rows with different superscript letters differ (P < 0.05).
