Assessment of Antibiotic Use in Grow-Finish Pigs After PRRSV Introduction in a PRRSV-Naïve Breeding Herd

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.

For today’s Science Page we bring you a study by Iowa State University researchers Isadora Machado, Thomas Petznick, Ana Paula Silva, Chong Wang, Locke Karriker, Daniel Linhares, and Gustavo Silva taking a look at the association between PRRSV-positive status and increased antibiotic usage in the growing pig population.

North Star and Lone Star states get together on livestock biosecurity

This article was written by Catherine Dehdashti and originally published in the University of Minnesota Extension's Magazine Source. Since this piece has been written, the first case of H5N1 influenza has been reported in a non-commercial pig in Oregon. Read Dr. Marie Culhane's comments in this article.

Like Minnesota, the state of Texas is strong in livestock. But Minnesota, including University of Minnesota Extension’s livestock team, has long led in research and education on preventing the spread of disease among farms, especially since the 2015 outbreak of H5N1 highly pathogenic avian influenza and the 2024 spread of avian influenza into dairy cows.

A Review of MSHMP PED Chart 3: PED Outbreak History

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).
