β-葡聚糖对暗纹东方鲀幼鱼非特异性免疫及生长性能的影响
Effect of β-glucan on the non-specific immunity and growth of Taki-fugu obscurus
摘要
Abstract
Takifugu obscures is a special economic species in China. Under the artificial aquaculture, the toxicity in this species decreases, which makes the fish consumption more widely than before. But the ability of anti-diseases decreases under aquaculture condition, which restricts the development of the aquaculture industry for this species. We used healthy juvenile specimens of T. obscures at body weight about 50 g. According to the requirement of this study we designed item trials with 3 replicates for each. The fish were administeredβ-glucans either by injection or orally (in feed). We subsequently experimentally infected each individual with Aeromonas hydrophila at various times after injection withβ-glucan. We observed an increase in serum lysozyme (LZM), catalase (CAT), total se-rum protein (TSP), and superoxide dismutase (SOD) (P<0.05), but not complement 3(C3). Intraperitoneal injec-tion ofβ-glucan significantly enhanced survival. Oral administration ofβ-glucan enhanced non-specific immunity (P<0.05), but had no effect on weight percent gain (WPG) and specific growth rate (SGR) (P>0.05). There was no difference in the non-specific immune response between groups that received continuous administration and those that received a single dose. Thus, we recommend use of a single injection to prevent immunological suppression.关键词
