Animal Well-being - Depopulation
Characterizing the Distribution of Water-Based Foam and High-Expansion Nitrogen Foam Within the Swine Respiratory Tract Using Computed Tomography

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.

Quantifying a Technique Using Carbon Monoxide for the Depopulation of Swine

The project demonstrated the euthanasia of mature sows and feeder pigs using carbon monoxide (CO) produced by a 1970 gas grain truck. The gas engine system, with no modifications, had been previously used to euthanize weaned pigs. This project further improved the method by cooling and filtering particulates out of the exhaust gas prior to contact with the pigs.

Use of modified rendering trailers to achieve rapid depopulation of modern sow units

The objective of this project was to establish an effective and safe method to facilitate both the depopulation of sow units and the disposal of carcasses in the face of a foreign animal disease outbreak.
