Monitor outcomes

Monitor outcomes to ensure long-term PRRS control success. Track diagnostic results and pig performance data across sow, grow-finish, and whole production systems to detect low-level virus circulation, guide decisions, and move herds toward stable or negative status.

Guilty Guilt Guide

The Guilty Gilt Guide was written with a clear objective – to maximize the whole-herd performance of pig populations by helping gilts to reach their full reproductive potential and produce healthy pigs that reach their full genetic potential during grow-finish.

Implementing a user-friendly format to analyze PRRSV next-generation sequencing results and associating breeding herd production performance with number of PRRSV strains and recombination events

The open reading frames (ORF)5 represents approximately 4% of the porcine repro- ductive and respiratory syndrome virus (PRRSV)-2 genome (whole-PRRSV) and is often determined by the Sanger technique, which rarely detects >1 PRRSV strain if present in the sample.

Decision model development for application of PRRS mitigation strategies post-weaning

Pork production systems routinely capture large amounts of real-time data. Decision tools can be developed to effectively utilize this data in strategic decision making. For example, Porcine Reproductive and Respiratory Syndrome (PRRS) creates economic losses in the period from weaning to market (WTM).1 Several tactics can be employed to mitigate these losses in WTM batches. However, understanding the mean cost of PRRS infection in a batch of pigs and the ability to predict which batches are most likely to suffer those losses are critical in designing mitigation strategies that optimize economic returns. This paper describes an economic decision model for PRRS mitigation strategies in WTM pigs that was constructed and applied within a large production system.

Assessment of the economic impact of porcine reproductive and respiratory syndrome virus on United States pork producers

After a previous article from 2005 the goal was to reassess the current cost of PRRSV in the swine industry.
Using the productive data of 80 US commercial breeding herds and 639 groups of growing pigs that were on different health status regarding PRRSV infection, it was possible to determine how the main KPI (Key Performance Indicators) are affected by PRRS.

Costs for having and not having PRRS

PRRS is a pig disease causing large economical losses. Sweden has been free from PRRS, which since 1998 has been documented by a control program. However, in 2007 the country was hit with PRRS. PRRS was promptly eradicated 1, 2, and the control program was redesigned. The present report discusses the cost for controlling and documenting freedom from PRRS and relates that to costs for having the disease.

Current incidence, prevalence and state of control of PRRS virus in North America

Porcine reproductive and respiratory syndrome virus (PRRSV) has been reported to be the most costly pathogen causing reproductive disease and decreased growth performance.  The virus continues to evolve and considerable variability exists among isolates in virulence, apparent protection from vaccination and our time required to eliminate the virus from sow herds. Lacking any data on prevalence or incidence in the industry, we started a Swine Health Monitoring Program in 2012 (Tousignant et al).
