Model predictions. Model predictions illustrating the effect of herd size (x-axis) and length of restriction period (size of dots) on costs for controlling salmonella (y-axis) in dairy herds. Predictions are from a mixed linear regression model and are performed with serotype = Dublin, county = county of Kalmar (H), administrative change at the SBA = 2009–2013 and year = 2013
