Further assessment of air filtration for preventing PRRSV infection in large breeding pig herds

Alternatives to the use of antimicrobial agents in pig production: A multi-country expert-ranking of perceived effectiveness, feasibility and return on investment

“…In a similar way, disease prevention through optimization of the climate and housing conditions of the pig can lead to a lower antimicrobial usage (Dee et al, 2012).…”

Financial implications of installing air filtration systems to prevent PRRSV infection in large sow herds

“…The probable importance of aerosol transmission of PRRSV was immediately recognized during the initial European PRRS epidemic 20 years ago (Desrosiers, 2004), yet steps to address this mode of transmission directly in North America have only been initiated relatively recently (Reicks, 2008;Spronk et al, 2010;Dee et al, 2010b). Although initial observations on reducing the risk of PRRS introduction on swine farms have been encouraging Alonso et al, 2013 companion paper), the substantial capital costs involved in fitting farms with air filtration systems are daunting to many producers.…”

“…In the US midwest, numerous sow farms have implemented air filtration systems in swine dense areas (Dee et al, 2010b;Spronk et al, 2010). The aim of the present study was to assess actual production data in filtered and non-filtered farms to determine potential productivity differences, and use observed differences to model the financial impact of two options for filtration interventions using a partial budget analysis.…”

Evaluation of the Long-Term Effect of Air Filtration on the Occurrence of New PRRSV Infections in Large Breeding Herds in Swine-Dense Regions

“…As a result of these findings, air filtration has been rapidly applied to commercial swine production [16,17]. In order to measure its effect, pilot studies were conducted in large breeding herds in regions of southern Minnesota and northern Iowa, USA, with a high density of pigs.…”
