摘要
2008年7月至2009年1月,应用酶联免疫吸附反应法对广东省茂名、惠州、东莞、四会、鹤山5个地区的40个中小规模猪场进行了猪繁殖与呼吸综合征(PRRS)的血清学调查。结果显示,未进行疫苗免疫接种的猪场PRRSV的感染率高达100%,平均抗体阳性率为66.77%,其中后备母猪为87.50%,生产母猪为80.77%,仔猪为57.21%;进行过疫苗免疫接种的猪场PRRS平均抗体阳性率82.82%,其中后备母猪为87.06%,生产母猪为82.40%,仔猪为81.89%。由此可见,猪繁殖与呼吸综合征野毒在广东省中小规模猪场普遍存在,而且感染率差异显著(P<0.01),这可能与各个猪场的饲养环境、管理水平和防疫措施等有关。
In order to grasp the infection of porcine reproductive and respiratory syndrome in some small and medium scale pig farms in Guangdong,thus obtain the danger to the production of pig-breeding,and make a reasonable assessment to prevent and control porcine reproductive and respiratory syndrome,ELISA was used to take a serological investigation of porcine reproductive and respiratory syndrome virus infection in 40 small and medium scale pig farms in Maoming Heshan,Huzhou,Dongguan,Sihui Heshan.The results showed that for those not vaccinated the infection rate was as high as 100%,and infection rate of sows was 80.77%,back-up sows was 87.50%,piglets was 57.21%.Vaccined pigs had an average positive rate 82.82%,reserve sows 87.06%,productive sows was 82.40%,piglets was 81.89%.It can be seen that PRRSV exist widely,and the infection rates is significant in small and medium scale pig farms in Guangdong,this may be associated with pig raising environmernt,management level and disease control measures.
