摘　　要：利用微生态制剂（Ｊｙ１０节杆菌ＡｒｔｈｍｏｂａｃｔｅｒＳＰ，Ｊｙ３１乳杆菌Ｌａｔｏｂａｃｉｌｕｓｃａ－ｓｅｉ制成的活菌制剂）饲养并定期灌喂鲤，３０－３５天后在低温条件下感染致病菌，观察死亡率、发病情况和测定各项生理生化指标。结果表明，微生态制剂实验组死亡率明显低于对照组，半数致死量（ＬＤ５０）１０－０．７９９高于对照组１０－０．９２１，差异显著（Ｐ＜０．０５）；血清总蛋白、ｒ－球蛋白、血糖量、血脂量、红细胞脆性、脑胆碱酯酶活力及白细胞吞噬功能等。With a compound ecological preaparation (a living bacterium preparation of Arthmobacter SP, and latobacillus casei) used as pilled ration additive,a trial of raising overwintering for hybrid carp's ability was carried out in 1994. After 30-50 days,the test and control fish groups were infected with pathogenetic bacteria under lower temperature condition.The experiment result showed that the survival rate of the test group with lethal dose 50%(LD 50 )was apparently higher than that of the control,and the serum total protein and r-globutin,serun glucose content and total lipid,fragility of Rbc,brain AchE,leucooyte phagocytosis,etal were all higher than those of the control too.
