【摘要】：口蹄疫(Foot-and-mouth disease,FMD)、豬繁殖與呼吸綜合征(Porcine reproductive and respiratory syndrome,PRRS)、豬瘟(Classical swine fever,CSF)是近年來危害養(yǎng)豬業(yè)的重要傳染病,口蹄疫、豬瘟被世界動物衛(wèi)生組織列為A類家畜傳染病,豬繁殖與呼吸綜合被征列為B類傳染病。這3種病是我國重點防控的疫病。預(yù)防CSF、PRRS、FMD 3種疫病最有效的方法是疫苗免疫接種。我國對豬疫病采取的是以疫苗免疫接種為主的綜合防控措施,而對疫苗免疫效果的評價主要是檢測免疫抗體水平,當(dāng)抗體水平達到相應(yīng)的滴度,便可起到防止相應(yīng)病原感染的作用。對疫苗免疫抗體水平的檢測是規(guī)�；B(yǎng)豬場疫病檢測的一項重要內(nèi)容,是規(guī)模化養(yǎng)豬場制定疫病防控方案的重要依據(jù)。本研究針對許昌市下轄5個縣區(qū)規(guī)�；B(yǎng)豬場疫病防控中疫苗免疫接種的實際情況,分別采集五個縣區(qū)15家養(yǎng)豬場戶732份血清樣品,對豬瘟、豬O型口蹄疫、豬繁殖與呼吸綜合征3種主要疫病的疫苗免疫抗體水平進行了檢測和評價,以期為本地區(qū)規(guī)�；B(yǎng)豬場豬瘟、豬O型口蹄疫、豬繁殖與呼吸綜合征的防控提供基礎(chǔ)資料。調(diào)查結(jié)果如下。1.對許昌市規(guī)模豬場豬瘟、豬O型口蹄疫、豬繁殖與呼吸綜合征3種主要疫病免疫效果進行了檢測。結(jié)果表明,豬瘟免疫抗體合格率為70%~93.3%,2014年和2015年平均合格率分別為83.2%和79.8%;豬O型口蹄疫免疫抗體合格率為72.2%~93.3%,2014年和2015年平均合格率分別為82.4%和82%;豬繁殖與呼吸綜合征免疫抗體合格率為72.2%~96.4%,2014年和2015年平均合格率分別為85.9%和85.1%。2.豬場3種主要疫病疫苗免疫抗體檢測結(jié)果說明,5個縣區(qū)本次所抽檢規(guī)�；i場豬瘟、豬O型口蹄疫、豬繁殖與呼吸綜合征疫苗免疫抗體合格率達到了國家規(guī)定的要求,但各縣之間合格率水平仍有較大差距,抗體的整體陽性率有待提高。
[Abstract]:Foot-and-mouth disease (FMD), porcine reproductive and respiratory syndromes (PRRSs) and classical swine disease (CSFs) are the most important infectious diseases in swine industry. Foot-and-mouth disease (FMD) and hog fever (CSF) are classified as Class A infectious diseases by the World Organization of Animal Health (OIE). Porcine reproductive and respiratory syndromes are classified as Class B infectious diseases. These three diseases are the most important diseases in China. Vaccination is the most effective method to prevent three kinds of epidemic diseases. In our country, we take comprehensive measures to prevent and control pig blight by vaccination, and the evaluation of the immune effect of the vaccine is mainly to detect the level of immune antibody, when the antibody level reaches the corresponding titer. Can play the role of preventing the corresponding pathogen infection. The detection of immune antibody level of vaccine is an important content in the detection of epidemic disease in large-scale pig farms, and it is also an important basis for the establishment of prevention and control schemes of epidemic diseases in large-scale pig farms. In this study, 732 serum samples from 15 pig farms in five counties of Xuchang city were collected for swine fever and hog type O foot-and-mouth disease. In order to provide basic data for prevention and control of swine fever, hog type O foot-and-mouth disease and porcine reproductive and respiratory syndrome in this area, the immune antibody levels of three major diseases of swine reproductive and respiratory syndrome were detected and evaluated. The findings are as follows. The immune effects of swine fever, hog type O foot-and-mouth disease and porcine reproductive and respiratory syndrome on large scale pig farms in Xuchang city were detected. The results show that The qualified rate of antibody against hog fever antibody was 700.93. 3%, the average qualified rate in 2014 and 2015 was 83.2% and 79.8%, respectively, and the qualified rate of antibody against foot-and-mouth disease type O was 72.2%, and the average qualified rate in 2014 and 2015 was 82.4% and 822%, respectively. The average qualified rate in 2014 and 2015 was 85.9% and 85.1%, respectively. The test results of immune antibodies against three kinds of major epidemic disease vaccines in pig farms show that the qualified rate of immunized antibodies against swine fever, hog type O foot-and-mouth disease and porcine reproductive and respiratory syndrome vaccines in five counties and regions has met the requirements of the state. However, there is still a big gap in the qualification rate among counties, and the overall positive rate of antibody needs to be improved.
