Four diets supplemented with three different levels of β-1,3-glucan (0.5, 1, and 2 g kg) were formulated and tested for growth, intestine digestive-enzyme activities, PO, SOD and GPx activities and erythrocytes number, phagocytic percentage of erythrocytes and lysozyme activity and resistance to Aeromonas hydrophila of loach Paramisgurnus dabryanus. A diet without any β-1,3-glucan served as the control. After 60 days of feeding, the growth performance, intestine digestive-enzyme activities, nonspecific immunity, and resistance to Aeromonas hydrophila of P. dabryanus were higher than those of the control when the loaches P. dabryanus were fed with β-1,3-glucan-containing diets. Results revealed that dietary β-1,3-glucan can improve the growth performance, intestine digestive-enzyme activities, PO, SOD and GPx activities and erythrocytes number, phagocytic percentage of erythrocytes and lysozyme activity and resistance of loaches P. dabryanus and can thus be used as their diet supplement.
四种饲料中添加了三种不同水平的β-1,3-葡聚糖（0.5、1 和 2g/kg），用于生长、肠道消化酶活性、过氧化物酶（PO）、超氧化物歧化酶（SOD）和谷胱甘肽过氧化物酶（GPx）活性以及红细胞数量、红细胞吞噬百分比和溶菌酶活性以及对嗜水气单胞菌的抗性的测试。不含任何β-1,3-葡聚糖的饲料作为对照。经过 60 天的喂养，当饲料中添加β-1,3-葡聚糖时，泥鳅的生长性能、肠道消化酶活性、非特异性免疫力以及对嗜水气单胞菌的抗性均高于对照组。结果表明，日粮β-1,3-葡聚糖可以提高泥鳅的生长性能、肠道消化酶活性、PO、SOD 和 GPx 活性以及红细胞数量、红细胞吞噬百分比和溶菌酶活性以及对泥鳅的抗性，因此可以作为其饲料补充剂。
