Use of water-based foam to achieve rapid depopulation of swine: Assess physiological and behavioral effects in swine exposed to 5 different water-based foam products
March 10, 2025By Andrew Bowman
Swine herds in the United States are susceptible to introductions of catastrophic diseases that may require mass depopulation for timely disease containment. Current options for depopulating swine, as outlined in the AVMA Guidelines for the Depopulation of Animals face logistic constraints, pose significant worker safety risks, and may not be practical at large scales.

Characterizing the Distribution of Water-Based Foam and High-Expansion Nitrogen Foam Within the Swine Respiratory Tract Using Computed Tomography
June 29, 2024By Andrew Bowman
This study was conducted to explore the distributions of class A water-based foam and high-expansion nitrogen foam within the respiratory tract of pigs using computed tomography (CT), which is a real-time imaging technology. Through this, the goal was to further describe how foam-based swine depopulation methods, specifically water-based foam and high-expansion nitrogen foam, work in depopulated pigs.

Development of an interactive training app for timely and humane on-farm euthanasia in pre-weaned piglets
July 16, 2018By Dr. Monique Pairis-Garcia Ph.D.
Euthanasia is a necessary act for any operation keeping live animals. However, science-based guidance for pig producers on proper on-farm decision criteria for euthanasia in piglets is deficient.

Pigs play a critical role in the ecology and epidemiology of influenza A viruses (IAVs) by serving as a source of novel reassortant viruses infecting humans. Agricultural fairs and livestock...
Evaluation of cross-protective immunity induced by porcine intestinal mesenchymal stromal cell-adapted PEDV
June 16, 2017By Mahesh Khatri
Porcine epidemic diarrhea virus (PEDV) which was isolated in 2013 in the US is causing huge economic losses to Pork Industry. PEDV causes an acute enteric infection in pigs of all ages but infection...

Epidemiological surveillance of influenza A viruses in pigs entering swine exhibitions
December 1, 2015By Andrew Bowman
Swine play a key role in the evolution and ecology of influenza A virus (IAV) infecting humans as pigs are a host species in which reassortment of the IAV segmented genome commonly occurs. Due to the...
