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.
对20只圣伊内斯母羊的血液和乳汁分泌物中的免疫指标和氧化应激标志物进行了分析，这些母羊分为两种饲养方式：棉籽浓缩料（CS组；n = 10）和大豆浓缩料（SB组；n = 10）。SB组的血液过氧化氢酶活性和氧自由基吸收能力高于CS组（P<0.05），这表明棉籽会增加母羊的氧化应激。食用棉籽会增加初乳中的IgG浓度、溶菌酶活性和总蛋白浓度，并降低铁储备，这表明这种营养物质对初乳的免疫质量、抗菌活性和抗氧化潜力有积极影响。
