生态制品（Jy10、Jy31复合制剂）饲料添加剂对提高鲤抗病力的研究

应用从正常、健康鲤肠道中分离筛选出的无毒、无害菌群（Ｊｙ１０节杆菌Ａｒｔｈｒｏｂａｃｔｅｒｓｐ．Ｊｙ３１干酪乳杆菌Ｌａｃｔｏｂａｃｉｌｌｕｓｃａｓｅｉｓｕｂｓｐｒｈａｍｎｏｓｕｓ）制成生态制品，作为料饲添加剂，饲养鲤。应用结果表明：投喂生态制剂组鲤不仅生长快、而且提高了抗病力，其白组胞吞噬率，白细胞吞噬指数，巨噬细胞吞噬率，Ｅ玫瑰花环形成率（Ｅａ率Ｅｔ率）均高于对照组（未投喂生态制组）．生态制剂投喂组鲤受到攻击后不仅成活率提高且对待攻击菌形成的特异性抗体效价也显著提高。说明生态制品饲养鲤，对提高其免疫水平及抗病力具有积极作用，同时也具有防病和治病的效果。

THE INVESTIGATION OF COMPOUND ECOLOGICAL PREPARATION(JY10 AND JY 31)ON IMPROVEMENT OF CARP'S DISEASE RESISTANCE

Nonpoisonous and harmless bacterial floras(y10,Arthrobacter sp;Jy31,Lactobacillus Casei Subsp rhamnosus)which were isolated and selected from intestinal tract of normal and healthy carp were prepared as compound ecological preparation,This preparation was given to the carp as fodder additive.The results showed that thc experimental groups fed with the ecological preparation not only grew fast but also their disease resistance wras improved as well,Their leucocyte pha- gocytic rate and index,macrophage phagocytic rate and erythrocyte rosette formation rate were higher than those of control groups(not fed with ecohgical preparation).when the experimental groups were attacked by attacking bacteria,their survival rate and specific antibodyagainst the attacking bacteria were higher compared with the controlgroups.These results illustrated that the ecological preparation can notonly improve the carp's immune level and disease resistance but alsoplay a great role in prevention and treatment diseases.
