摘要
为了解壳聚糖和益生菌刺激和增强免疫应答的可能作用,本试验在基础饲料中添加0.2%、0.5%、1.0%的壳聚糖,0.1%、0.2%、0.4%的益生菌,甘露聚糖与益生菌混合物,壳聚糖与益生菌的混合物,在室内水泥池中喂养暗纹东方鲀(3.15±0.05)g 2个月,根据抗菌活力筛选出免疫增强饲料组(0.2%壳聚糖,0.1%、益生菌,甘露聚糖与益生菌混合物,壳聚糖与益生菌混合物)测定免疫功能。结果表明,甘露聚糖与益生菌混合物仅提高头肾T淋巴细胞转化,壳聚糖与益生菌混合物显著增强头肾T、B淋巴细胞转化和脾脏B淋巴细胞体外培养时分泌的IgM。筛选出的四种免疫增强饲料均能使头肾B淋巴细胞体外培养时分泌的IgM显著增加。无论是脾脏B淋巴细胞还是头肾B淋巴细胞,体外培养时所分泌的IFN-α都不同程度地受抑制。
