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.
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.
Porcine reproductive and respiratory syndrome virus (PRRSV) is an important swine pathogen affecting the global swine industry.
Mycoplasma hyopneumoniae (M. hyopneumoniae) infections continue to result in significant respiratory challenges in the swine industry worldwide. Vaccination for M. hyopneumoniae is commonly utilized, as reduction in bacterial loads and clinical severity in vaccinated pigs have been shown. However, the effect of M. hyopneumoniae vaccination on transmission across different pig populations has been minimally investigated.

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.
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.
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).
Porcine Reproductive and Respiratory Syndrome (PRRS) is the most costly viral disease in pigs around the world. Estimated annual costs in the US alone are $664 million (Holtkamp et al. 2013). Although much emphasis has been placed on development of preventative measures to control the spread and impact of PRRS, including vaccination and regional eradication efforts, PRRS continues to be a major problem in the industry (Darwich et al. 2010, Huang and Meng, 2010, Chand et al. 2012).
