雏鸭沙门氏菌病是由一类沙门氏杆菌引起雏鸭以下白痢为主的急性传染病,发病率30～40％,病死率可高达80％以上,常呈地方性流行,给养鸭业带来极大损失。对该病治疗法虽多,但疗效不佳,特别是滥用抗生素使其肠道菌群失调,耐药菌株增多,致使疗效降低或无效,为克服抗生素所造成的弊病,寻求理想的防治药物和提高经济效益的新途径,作者用新型活菌制剂调痢生对该病进行了防治试验。试验分预防和增重试验、治疗试验,自然病例病原的分离与人工感染治疗试验三部分。试验药物
Ducklings Salmonellosis is caused by a class of Salmonella ducklings following white dysentery-based acute infectious diseases, the incidence of 30 to 40%, the mortality rate can be as high as 80% or more, often endemic, to bring the duck industry Big loss Although the treatment of the disease is many, but the curative effect is poor, especially the abuse of antibiotics to make its gut flora, increased resistance strains, resulting in reduced or ineffective treatment, to overcome the shortcomings caused by antibiotics, to seek the ideal prevention and treatment of drugs and Improve the economic benefits of new ways, the author with a new live dysentery agent dysentery control of the disease were tested. Test points for prevention and weight gain test, treatment test, the separation of natural case pathogens and artificial infection treatment test in three parts. Test drug
