【摘要】 本研究旨在探究日粮中添加壳寡糖对白羽王鸽生产性能、免疫器官指数、屠宰性能和免疫性能的影响。结果表明：添加不同量的壳寡糖可改善白羽王鸽生产性能，与对照组相比，COSL组、COSM组、COSH组的料重比显著（p<0.05）降低。添加壳寡糖可改善白羽王鸽的屠宰性能，与对照组相比，COSL组、COSM组、COSH组的白羽王鸽全净膛率和半净膛率显著提高。与对照组相比，COSM组、COSH组显著提高了白羽王鸽血清中蛋白（TP）、白蛋白（ALB）、球蛋白（GLB）、免疫球蛋白A（IgA）、免疫球蛋白G（IgG）、免疫球蛋白M（IgM）含量，显著降低了肿瘤坏死因子（TNF-α）含量。与COSM组相比，COSH组ALB含量显著提高，TNF-α含量显著降低。与对照组、COSL组相比，COSM组、COSH组总抗氧化能力（T-AOC）、超氧化物歧化酶（SOD）活性、谷胱甘肽过氧化物酶（GSH-Px）活性、过氧化氢酶（CAT）活性均显著提高，丙二醛（MDA）含量显著降低。COSH组SOD、GSH-Px、CAT活性显著高于COSM组。本试验条件下，白羽王鸽饲粮中添加400 mg·kg^-1壳寡糖效果最佳。更多还原

【Abstract】 The aim of this study is to investigate the effects of adding chitosan oligosaccharide to the diet on the production performance, immune organ index, slaughter performance, and immune performance of Columba. The results showed that adding different amounts of chitosan oligosaccharides to the diet could improve the production performance of Columba. Compared with the control group, the feed to weight ratios of the COSL group, COSM group, and COSH group were significantly（p<0.05） reduced. Adding chitosan oligosaccharide to the diet can improve the slaughter performance of Columba. Compared with the control group, the full clearance rates and semi clearance rates of Columba of the COSL group, COSM group, and COSH group were significantly increased. Compared with the control group, the COSM and COSH groups significantly increased the contents of total protein（TP）, albumin（ALB）, globulin（GLB）, immunoglobulin A（IgA）, immunoglobulin G（IgG）, and immunoglobulin M（IgM） in the serum of Columba, while significantly reducing the content of tumor necrosis factor alpha（TNF-α）. Compared with the COSM group, the COSH group showed a significant increase in ALB content and a significant decrease in TNF-α content. Compared with the control group and COSL group, the COSM group and COSH group showed significant increases in total antioxidant capacity（T-AOC）, superoxide dismutase（SOD） activity, glutathione peroxidase（GSH-Px） activity, catalase（CAT） activity in serum, while malondialdehyde（MDA） content was significantly reduced. The SOD activity, GSH-Px activity, and CAT activity in the COSH group were significantly higher than those in the COSM group. Under the conditions of this experiment, the addition of 400 mg·kg^-1 chitosan oligosaccharide to the diet for Columba showed the best effect.更多还原
