为中草药添加剂在青田田鱼养殖上的应用提供参考,根据中医理论结合贵州得天独厚的中草药植物资源,将黄芪、党参等10余味中草药按比例配制后在饲料中添加2%~8%,进行7d预试验和40d正式试验,研究其对青田田鱼增重、血常规及红细胞免疫功能的影响,以筛选出最佳使用剂量。结果表明:以添加6%的效果最好,与相应对照组比较,平均增重15.63g/尾,单核细胞百分数(MONO%)极显著降低,淋巴细胞百分率(LYMPH%)、大未染色细胞百分数(LUC%)、大未染色细胞绝对值(LUC#)、红细胞计数(RBC),血红蛋白(HGB)显著增加;IgM免疫球蛋白含量显著增加。结论,黄芪等组配的中草药饲料添加剂可作为青田田鱼促生长剂和机体免疫增强剂使用,其中以添加6%的剂量为宜。
According to the theory of Chinese medicine combined with the unique medicinal plant resources of Guizhou, the traditional Chinese medicine additive was added to the feedstuffs in a proportion of 2% ~ 8% for 7d Test and 40d formal test to study the Qingtian Tian fish weight gain, blood and erythrocyte immune function, in order to screen the best dose. The results showed that the best addition of 6%, the average weight gain of 15.63g / tail, monocyte percentage (MONO%) decreased significantly, the percentage of lymphocytes (LYMPH%), large undyed cells LUC%, LUC #, RBC and HGB were significantly increased; IgM immunoglobulin content was significantly increased. Conclusion: Astragalus and other components of Chinese herbal medicine feed additives can be used as Qingtian Tian fish growth promoter and immune enhancer use, which add 6% of the dose is appropriate.
