猪传染性胃肠炎是猪的一种急性肠道传染病,为了减轻猪传染病胃肠炎疾病的发生,我们要弄清猪传染性胃肠炎疾病的病原,然后再采取相应的预防和治疗措施,减少或降低猪传染病胃肠炎疾病的发生.本文分析了猪传染性胃肠炎疾病的临床症状、流行病学、病理变化、诊断方法、同时也提出了几点相应的预防和治疗措施,并分别对其进行了探讨研究. 相似文献

猪传染性胃肠炎是由传染性胃肠炎病毒引起猪的一种高度接触性消化道传染病。其发病后表现为严重的腹泻和脱水症状,不仅严重影响到猪的生长发育,还能够导致猪的死亡,对养猪场造成极大的经济损失。本文针对猪传染性胃肠炎的病原、传播途径、临床症状、病理变化、诊断方法进行详细的剖析,并对本病的预防和治疗提出了具体的措施,为养猪场对猪传染性胃肠炎的防控提供参考。 相似文献

研究复方中草药对猪传染性胃肠炎的临床疗效,对复方中草药防治猪传染性胃肠炎的方法进行完善。选用复方中草药方剂"乌梅散"、"胃苓汤"、"白龙散"、"白头翁汤"分别对自然感染且具有明显猪传染性胃肠炎临床症状的患猪进行治疗,同时比较四种复方中草药预防猪传染性胃肠炎病的效果。发现"乌梅散"、"胃苓汤"、"白龙散"及"白头翁汤"经口服治疗治愈率分别为77.50%、62.50%、75.00%、50.00%;经口服预防未发病率为80.00%、70.00%、90.00%、40.00%,这表明复方中草药对于防治猪传染性胃肠炎有效,其中"乌梅散"的治疗效果较理想,"白龙散"的预防效果较好。复方中草药具有抗猪传染性胃肠炎的效果可以对该病进行防治,但临床预防效果高于治疗效果。 相似文献

猪的 2 0多种传染病 ,有不少在冬春发生 ,原因主要因冬春气候变化无常 ,猪体抵抗力弱。最常见的有猪瘟、仔猪副伤寒、喘气病、猪流感、传染性胃肠炎、仔猪黄白痢等。猪瘟、喘气病、猪流感、传染性胃肠炎等由病毒致病 ,没有特效药治疗 ,只能用疫苗预防。副伤寒和黄白痢由细菌致病 ,可用疫苗预防 ,也可药物治疗。在上述猪病中 ,猪瘟、猪副伤寒死亡率最高 ,其次是猪黄白痢。猪流感、喘气病、传染性胃肠炎死亡率较低 ,但一旦侵害了猪群、猪生长发育迟缓 ,有的还成为僵猪 ,迟迟不能出栏 ,使养猪效益下降。猪病贵在预防。目前除流感和传染性胃肠炎… 相似文献

春季是猪病多发季节,最常见的有猪瘟、仔猪副伤寒、猪流感、传染性胃肠炎、仔猪黄白痢等。猪瘟、猪流感、猪传染性胃肠炎等由病毒所致,只能用疫苗预防。仔猪副伤寒和黄白痢由细菌所致,可用疫苗预防,也可药物治疗。在上述猪病中,猪瘟、仔猪副伤寒死亡率最高,其次是猪黄、白痢。猪流感、猪传染性胃肠炎死亡率较低,但可导致猪生长迟缓,使养殖效益下降。为此,养猪户最好提前采取各项防病措施。 相似文献

Clinical, immunofluorescence and histopathological observations were found to be an efficient approach for the confirmation of the diagnosis of transmissible gastroenteritis in feeder swine. Two cases are reported to exemplify how feeder swine exposed to points of concentration such as holding areas, sales barns and auctions can play an important role in the epizootiology of transmissible gastroenteritis. A third field case is reported as an example of an outbreak of transmissible gastroenteritis beginning in feeder swine and then spreading to baby pigs on the farm. All baby pigs died that were born during the acute phase of the outbreak in the feeder swine. Baby pigs born shortly after the clinical signs had abated in the herd, and from sows that had been exposed orally to virulent transmissible gastroenteritis virus and vaccinated with a commercial transmissible gastroenteritis vaccine ten days before farrowing, survived. This was explained by a combination of a decrease in the amount of virus shed in the environment and the immunity induced in the sows. These observations of field outbreaks of transmissible gastroenteritis combined with recently reported experimental studies lend strong support to the hypothesis of a reservoir for transmissible gastroenteritis virus in feeder pigs. This reservoir would be based principally on the transmission of the virus on a continuous basis from the feces of recently infected pigs to susceptible pigs. Clinical signs of transmissible gastroenteritis in such pigs are difficult to recognize or absent and this contributes to the importance of the reservoir in the field. 相似文献

面对当前奶牛疾病防治的日益困难,虽然不乏众多新进展与新成果,而其临床防治却依旧是步履维艰;在用复杂性科学理论对其进行分析的基础上认为,其主要原因是传统科学“单因素线性分析”的简单化认识观念与方法不能适应临床疾病的复杂多变性特点,而转变科学观念,以复杂性科学理论为指导,加强其临床疾病复杂多变性特点和规律的认识与把握,也许才是突破其发展瓶颈的关键所在.其次,要实现奶牛疾病防治的复杂性科学转变,离不了中兽医药学辨证施治(状态分析与处理)在认识方法上的支撑与帮助;而奶牛疾病防治,有可能成为中西兽医药学结合发展的最重要用武之地之一. 相似文献

猪腹泻是全球养猪生产中最常见的疾病之一,病毒性腹泻具有传播快、致死率高和防控难的特点。常见的引起仔猪腹泻的病毒包括猪流行性腹泻病毒(PEDV)、猪传染性胃肠炎病毒(TGEV)和猪轮状病毒(PoRV),近几年新发现的猪δ冠状病毒(PDCoV)、猪嵴病毒(PKV)和猪急性腹泻综合征冠状病毒(SADS-CoV)也与仔猪腹泻相关。病毒分离是病毒感染诊断的金标准,也是进行病毒研究的前提。对上述6种常见猪肠道病毒的分离进展进行综述,可为掌握这些病毒的分离情况、疾病发展动向监测、疫苗研发以及猪腹泻病的防控提供参考。 相似文献

Precipitating antibodies against transmissible gastroenteritis viral antigens were detected by the immunodiffusion test in two transmissible gastroenteritis viral hyperimmune antisera and in antiserum prepared against haemagglutinating encephalomyelitis virus but not in sera from several species of normal animals, in antisera prepared against a variety of othet viruses and bacteria or sera from swine with bacterial enteritis. When the immunodiffusion test was compared with the virus neutralization test for the detection of transmissible gastroeneritis viral antibodies in 20 swine sera certain samples which contained high titres of virus neutralizing antibodies failed to produce precipitation while other sera were positive in the immunodiffusion test although their virus neutralizing antibody titres were relatively low. Precipitating antibodies were also detected by immunodiffusion in several samples of milk whey from a sow which had been vaccinated with inactivated transmissible gastroenteritis virus. 相似文献

通过对断奶仔猪投服不同剂量的中药免疫增强剂,研究其对猪瘟疫苗免疫调节作用的影响。试验组在注射猪瘟疫苗同时以1%的中药免疫增强剂混饲,其猪瘟血清抗体效价明显高于对照组,差异显著(P〈0.05);接种疫苗后15d和45d,试验组T淋巴细胞的百分率显著高于对照组(P〈0.05)。试验表明,猪只在接种猪瘟疫苗的同时服用中药免疫增强剂,能显著增强猪瘟疫苗的免疫效果,促进T淋巴细胞的增殖,增强其免疫力。 相似文献
