Justin Kieffer

Justin Kieffer's research focuses on animal welfare and emergency management practices in livestock production, particularly methods for mass depopulation (rapid, large-scale euthanasia) of swine, cattle, sheep, and goats during disease outbreaks or other emergencies. Much of the work evaluates water-based foam, gas-based, and electrical/mechanical euthanasia techniques by measuring welfare indicators such as brain activity, behavior, and postmortem findings, alongside stakeholder perceptions of these methods. Additional work touches on livestock reproduction and health topics such as reproductive synchronization protocols and disease surveillance in cattle.

Publication output has grown over the past decade, rising from little to no output in 2017-2018 to a peak in 2023, with continued activity through 2025.
