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.
