正随着冬天的来临,气温下降。河北辛集市多个养猪场发生以水样腹泻,呕吐、脱水和新生仔猪高病死率为症状的传染病。笔者根据临床症状分析为猪传染性胃肠炎和流行性腹泻混合感染所致。猪传染性胃肠炎和流行性腹泻是猪的一种高度接触性、消化道传染病。以呕吐、水样腹泻、和脱水为特征。猪传染性胃肠炎和流行性腹泻在临床方面无显著差别,只是猪传染性胃肠炎比猪流行性腹泻病死率 相似文献

猪球虫病属于流行性疾病,在猪群饲养管理中也是让管理者非常头痛的一种传染病,尤其是仔猪体质弱小,极易感染发病,引起仔猪生长缓慢、体重增加不足、甚至较高的死亡率,即使治愈后,很长一段时间内仔猪消化系统才能慢慢恢复,致使仔猪饲料利用率大大降低,给养猪场带来巨大的经济损失.在此就猪球虫病的症状和治疗方案进行总结. 相似文献

近20年来,商品化养猪场的猪群健康状况有了相当大的提高。虽然许多重要的疾病已被消灭,但仍然存在着若干较温和的地方病(如球虫病),它们会显著提高养猪生产成本。 相似文献

<正>2007年3月10日,河北省元氏县赵同乡龙正村李某打来求诊电话,称其喂养的两头母猪突然出现腹泻症状。没过几天,这两头母猪生下的已30天还正在吃奶的22头仔猪和另外3头70千克左右的育肥猪也全部出现水样腹泻。笔者急忙前去诊治。 相似文献

2007年6月成都周边某猪场发生了一种以发热、水样腹泻、呕吐等为主要特征的疾病。结合临床症状、病理剖解及历史发病情况,初步将此病例判断为猪传染性胃肠炎。猪传染性胃肠炎为病毒感染,以灰色水泥状下痢、呕吐、脱水为主:四季均有发病,冬春季节(11月至下年4月)为高峰期;大猪很少死亡,10日龄以下仔猪死亡率达50%~100%;尚无理想疫苗。 相似文献

鸡球虫病及抗球虫药物的临床应用 总被引:1,自引:0,他引:1
鸡球虫病是养禽业中重要的常见病,它对养鸡生产的危害十分严重。据统计,我国每年用于防治鸡球虫病的药费迭数亿元人民币,占鸡病全部防治费用的近三分之一。球虫病流行的鸡群生长严重滞后,而且易诱发其他疾病,如大肠杆菌病、支原体病等。自上世纪40年代磺胺类药物用于养鸡生产以来。已先后有30多种药物投入临床应用,给现代养鸡业带来空前的发展。可以说,没有抗球虫药物的开发应用,就没有现代集约化养鸡业。然而,随着药物的广泛应用,球虫抗药性问题日趋严重。多药抗性或交叉抗药性的产生大大缩短了药物的商业使用年限。对鸡球虫病及球虫抗药性的调查、分析、诊断和研究是养鸡发展十分重要的前提。 相似文献

Floor-pen studies were conducted to ascertain whether coccidiosis could be prevented by using a drug added to the litter to preclude coprophagia and ingestion of infective oocysts. An experimental drug (1-pyrrolidinebutyramide, 2-methyl-alpha,alpha-diphenyl) was added to litter contaminated with sporulated Eimeria tenella oocysts. Thereafter 7-day-old broiler chicks were reared on the litter for a nine-day period. Mortality, lesion scores and dropping scores were the criteria selected to determine efficacy. Treatment of the litter at the lowest level (2.3 g kg-1) did not reduce the incidence or severity of the disease, whereas treatment at two higher levels (11.5 and 23.0 g kg-1) significantly reduced both (incidence and severity). The highest level was the most efficacious; however, drug toxicity was also encountered at this level. 相似文献

It is proposed that just as the stethoscope and thermometer are fundamental tools for individual medicine, production and health recording systems are fundamental tools for effective population medicine. Treatment and control of clinical diseases as the primary objective is no longer considered appropriate for livestock population. Disease in populations now describes a deviation between what is happening and what is expected to happen. This redefinition of disease implies that it is of multifactorial origin and thus a different problem solving approach must be implemented. Therefore, a swine enterprise must be considered as a system, a set of interdependent components continuously interacting to produce pork. As a system, it is characterized by certain properties: change, environment, counterintuitive behavior, drift to low performance, interdependency, and organization. A redefinition of diseases implies also that they are not only “treated” but managed. Management consists of planning, monitoring, evaluation, and analysis. For this process to be implemented successfully, a goal-directed recording system providing a farm-based infrastructure for problem solving is essential. Clinical problem solving (diagnosis) is thus based on epidemiological and demographic methods. 相似文献

防治鸡球虫病的新途径 总被引:7,自引:0,他引:7
利用中草药驱虫保健剂、球虫疫苗及从营养学角度来控制鸡球虫病,为鸡球虫病的防治开避了新的途径,可以避免使用化学合成药物及抗生不所带来的耐药性和药物残留,而且在实际应用中更具有安全性。 相似文献
