Farm level risk factors associated with severity of post-weaning multi-systemic wasting syndrome
چکیده انگلیسی

A cross-sectional study involving 147 pig farms across England was conducted in 2008-2009. Farm severity of post-weaning multi-systemic wasting syndrome (PMWS) was estimated through the use of an algorithm that combined data on post-weaning mortality, PMWS morbidity and proportion of porcine circovirus type 2 PCR positive pigs. Farms were classified as non/slightly, moderately or highly affected by PMWS. Data on potential PMWS risk factors were collected through interviews, on-farm assessment and serological sampling. Risk factors were identified using multivariable ordinal logistic regression and multivariable linear regression.Factors associated with increased PMWS severity were rearing growers indoors (OR = 23.7), requiring a higher number of veterinarian visits per year (OR = 9.6), having poorly isolated hospital pens (OR = 6.4), buying replacement boars (OR = 4.8) and seropositivity to Mycoplasma hyopneumoniae (OR = 4.29); factors associated with decreased PMWS severity were low stocking density for growers (OR = 0.07), adjusting diets at least three times between weaning and 14 weeks of age (OR = 0.12), and requiring visitors to be at least 2 days pig free (OR = 0.14).This study provides evidence of the association between environmental and management factors and PMWS severity, and suggests that other pathogens may be important co-factors for the disease. In addition, this study highlights the potential efficacy of biosecurity measures in the reduction/prevention of within-farm PMWS severity.
