Abstract

BACKGROUND

Porcine reproductive and respiratory syndrome (PRRS) is a major endemic pig disease worldwide and is associated with considerable economic costs.

METHODS

In Scotland, three abattoir surveys were conducted in 2006 (158 farms), 2012-2013 (94 farms) and 2017-2018 (97 farms) to estimate seroprevalence to PRRS virus (PRRSV) in commercial finishing pigs. These surveys covered around 79%, 59% and 66% of the Quality Meat Scotland assured farms slaughtering pigs in Scotland in 2006, 2012-13 and, 2017-18 respectively. In the 2006 survey, six pigs per farm were sampled and tested using the CIVTEST SUIS PRRS E/S test. In the 2012-2013 and 2017-2018 surveys, 10 pigs per farm were sampled and tested using the IDEXX PRRS X3 Ab test. A farm was considered positive if it had one or more seropositive samples.

RESULTS

The prevalence of positive farms was 45.6% (95% CI: 38.0-53.4), 47.8% (95% CI: 38.1-57.9) and 45.4% (95% CI: 35.8-55.3) in the 2006, 2012-2013 and 2017-2018 surveys, respectively, and 70%-75.5% farms did not change their status between sampling periods.

CONCLUSION

The prevalence of PRRSV exposure in Scottish pig herds was high and changed little from 2006 to 2018. These surveys have informed planning for a prospective PRRS control programme in Scotland.

摘要

背景

猪繁殖与呼吸综合征（PRRS）是一种全球性的主要猪传染病，与相当大的经济成本有关。

方法

2006 年（158 个农场）、2012-2013 年（94 个农场）和 2017-2018 年（97 个农场）在苏格兰进行了三次屠宰场调查，以估计商业育肥猪中 PRRS 病毒（PRRSV）的血清流行率。这些调查分别覆盖了 2006 年、2012-13 年和 2017-18 年在苏格兰屠宰猪的 Quality Meat Scotland 保证农场的约 79%、59%和 66%。在 2006 年的调查中，每个农场抽取 6 头猪，使用 CIVTEST SUIS PRRS E/S 试验进行检测。在 2012-2013 年和 2017-2018 年的调查中，每个农场抽取 10 头猪，使用 IDEXX PRRS X3 Ab 试验进行检测。如果一个农场有一个或多个血清阳性样本，则被认为是阳性农场。
