【摘要】：本论文通过对2013年至2015年江西地区猪场基本情况进行调查、统计和分析,了解江西省猪场生产的基本情况;对2013-2015年江西省部分猪场的猪瘟、猪蓝耳病和猪伪狂犬病进行血清学调查,为江西省养猪业的发展和提高提供有价值的资料,促进我省生猪养殖业的发展。1、江西地区猪场基本情况的调查2013-2015年,采用问卷调查和实地走访的方式,对江西省南昌、赣州、宜春(含新余、萍乡)、吉安、九江、上饶(含景德镇)、抚州(含鹰潭)七个地区的部分不同规模的猪场进行了调查,调查猪场共计979场(次),其中2013年173场(次),2014年349场(次),2015年457场(次)。调查内容包括猪场规模、生猪存栏情况、猪场员工的文化水平、水源、生产方式、生产水平、主要疫病发生情况、疫苗免疫情况等。调查范围涉及江西各地区的各个规模、层次的猪场,着重分析了我省猪场的基本情况、性能指标和不同规模猪场的差异情况。了解了我省养猪业的基本现状和存在问题,为提高我省养猪业的生产水平提供参考。2、CSF、PRRS、PR血清学调查2013-2015年,采集了江西省南昌、九江、赣州、吉安、宜春(含新余、萍乡)、抚州(含鹰潭)及上饶(含景德镇)地区806个不同规模猪场(次)的23681份血清样品,其中2013年为3818份,2014年为5998份,2015年为13865份。对采集的血样进行了猪瘟、猪繁殖与呼吸综合征(猪蓝耳病)和猪伪狂犬病(gB/gpI)的抗体水平调查,猪瘟病毒抗体的总阳性率为71.71%,蓝耳病病毒抗体的总阳性率为77.93%,伪狂犬病毒gB抗体的总阳性率为84.95%,猪伪狂犬病gpI抗体总阳性率(野毒感染率)为25.80%。不同地区和不同日龄猪的抗体水平存在一定的差异。
[Abstract]:Based on the investigation, statistics and analysis of pig farms in Jiangxi Province from 2013 to 2015, the basic situation of pig farm production in Jiangxi Province and the swine fever in some pig farms in Jiangxi Province from 2013 to 2015 were analyzed. The serological investigation of pig blue ear disease and pseudorabies was carried out in order to provide valuable information for the development and improvement of pig industry in Jiangxi Province, and to promote the development of pig breeding in Jiangxi Province. The investigation on the basic situation of pig farms in Jiangxi Province from 2013 to 2015. By means of questionnaires and field visits, some pig farms of different sizes in Nanchang, Ganzhou, Yichun (including Xinyu, Pingxiang, Ji'an, Jiujiang, Shangrao (including Jingdezhen) and Fuzhou (including Yingtan) in Jiangxi Province were investigated. A total of 979 pig farms were investigated, including 173 in 2013, 349 in 2014 and 457 in 2015. The contents of the investigation included the size of pig farm, the status of pig stock, the educational level, water source, production mode and production level of pig farm staff. The scope of investigation involves pig farms of various scales and levels in Jiangxi Province. The basic situation of pig farms in our province has been emphatically analyzed. The basic status and existing problems of pig industry in our province were understood, and the serological investigation of CSFU PRRSRS PR serological investigation in Jiangxi Province from 2013 to 2015 was provided as a reference for improving the production level of pig industry in Jiangxi Province. The serological investigation was carried out in Nanchang, Jiujiang, Ganzhou, Jiangxi Province. 23681 serum samples from 806 pig farms of different sizes in Ji'an, Yichun (including Xinyu, Pingxiang, Fuzhou (including Yingtan) and Shangrao (Jingdezhen)), The antibody levels of swine fever, porcine reproductive and respiratory syndrome (swine blue ear disease) and pseudorabies were investigated in 2013, 2014 and 2015, respectively. The total positive rate of swine fever virus antibody was 71.71, the total positive rate of blue ear virus antibody was 77.933, the total positive rate of pseudorabies virus GB antibody was 84.95 and the total positive rate of pig pseudorabies virus gpI antibody was 25.80. There were some differences in antibody level of day-old pigs.
