摘要The present study evaluated the effects of dietary p-glucan (0, 0.05%, 0.1%, and 0.2%) on growth performance after 42 days of feeding. Thereafter, rainbow trout (Oncorhynchus mykiss) were infected with Aeromonas salmonicida, and survival rates as well as the regulating processes of stress-and immune related factors were analyzed. In general, higher dietary beta-glucan levels obviously improved specific growth rate (SGR), weight gain (WG) and feed efficiency (FE) (P <= 0.05). Survival rates in beta-glucan groups increased significantly compared with the control group after A. salmonicida infection (P <= 0.05). Serum total superoxide dimutase (T-SOD), peroxidase (POD) as well as catalase (CAT) activities, and their mRNA expressions in the head kidney of fish in the beta-glucan groups generally increased to higher levels after infection, and more quickly, compared with in the control group. Serum lysozyme (LSZ) and its expression in the head kidney in p-glucan groups reached a higher peak earlier than in the control group.
