This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
During the 2016-17 MSHMP year, we introduced a graph, PED Chart 3, in response to the recurring question of if farms that break with PED had repeating histories of infection. The horizontal axis is shown at the top and indicates the number of farms that have broken in the current MSHMP season. New farms are added throughout the year as they break. On the vertical axis we list each of these farms’ PED historical number of breaks in past seasons. Outbreaks are colored in blue, a darker tone indicates that a farm has had more than one outbreak within the year, and grey indicates a lack of historical data (Figure 1).
