摘要
试验旨在研究不同药物对仔猪黄痢即致病性大肠杆菌的治疗效果,试验选取河南省济源市赵李庄某猪场自然感染、症状典型、符合试验要求的7日龄内的病猪40头,猪的品种为杜长大三元杂交品种。将试验猪随机分为4组,每组10头。选用发病死亡后或濒临死亡猪的病料,通过对病料中致病性大肠杆菌进行分离及培养、生化鉴定、药敏试验,从中筛选出3种治疗药物,在确保相同环境、相同饲养管理的条件下,分别对3组仔猪进行治疗,第4组为对照组。试验结果表明,头孢噻呋对仔猪黄痢的治愈率为90%,效果显著,能有效降低死亡率,减少损失;硫酸黏杆菌素的治愈率为60%,效果一般;恩诺沙星的治愈率为50%,效果最差。
In order to study therapeutic efficacy that different drugs on pathogenic Escherichia coli, the experiment selected 40 pigs 7 days old from a pig farm in natural infection in Jiyuan city of Henan and were randomly divided into 4 groups, each group of 10 head. Through to the diagnosis of pathogenic Escherichia coli were isolated and cultured, biochemical identification, drug sensitive test, selected from three kinds of drugs in the same environment. Same feeding and management conditions, respectively, for the three group piglets were treated, the management conditions, respectively, for the three group little pigs were treated. The experimental results show that, the cure rate of ceftiofur is 90%, the cure rate of polymyxin is 60%, the cure rate of enrofloxacin is 50%.
