Abstract

Immune indicators and oxidative stress markers were analyzed in blood and lacteal secretions of twenty Santa Ines ewes distributed in two feeding regimes: cottonseed concentrate (CS; n = 10) and soybean concentrate (SB; n = 10). Blood catalase activity and oxygen radical absorbance capacity were higher in SB than CS (P < 0.05), suggesting that cottonseed increased oxidative stress in ewes. Cottonseed consumption increased IgG concentration, lysozyme activity and total protein concentration in the colostrum and decreased iron stock, suggesting a positive effect of this nutrient on the immune quality, antibacterial activity and antioxidant potential of colostrum.
