When a crisis hits industrial farms β disease outbreaks, supply chain shutdowns, “too many animals, not enough profit” β the system has a backup plan. It’s not about compassion. It’s about protecting production and profits.
Animal Outlook exists to challenge that system β to expose what happens behind closed doors and to push the law, the markets, and the culture towards a truly just food system. Because of you, we’re able to confront some of the most disturbing policies shaping animal agriculture today. One of the most urgent β and least understood β is the American Veterinary Medical Association’s “depopulation” guidelines.
What is “depopulation” β and what is VSD+?
“Depopulation” is the industry’s sanitized term for killing large numbers of animals quickly during an emergency. The AVMA issues guidelines that tell veterinarians and companies which methods are (1) acceptable, (2) permitted in constrained circumstances, or (3) not recommended.
One of the most controversial methods is ventilation shutdown plus β VSD+.
In VSD+, operators seal animals inside a building, cut off ventilation, and add heat and humidity. Animals trapped inside experience extreme distress as the environment becomes unbearable.
During the COVID-19 pandemic, VSD+ was used on industrial pig and poultry farms when slaughter plants backed up, and animals were suddenly seen as excess inventory. In other words, when profit margins were threatened, killing became the solution.
Why the AVMA’s guidelines matter
The AVMA is viewed as an authority β policymakers, corporations, and media outlets look to its guidelines to justify what happens on farms. When the AVMA says a method like VSD+ is permitted in constrained circumstances, it gives industry a powerful shield.
That language sounds technical and neutral. But on the ground, it translates into real suffering. It tells companies: if your infrastructure fails, if you breed more animals than you can slaughter, or if a disease outbreak hits, you may be able to get reimbursed with taxpayer money for VSD+.
This is not a rare exception. It is a built-in feature of a system that treats animals as units of production, not as living beings.
How Animal Outlook is fighting back
Animal Outlook is working to change this at every level:
- Investigations: Our undercover work exposes what “depopulation” and everyday factory farm life really looks like for animals, cutting through industry PR.
- Legal advocacy: Our legal team challenges abusive practices and pushes for stronger protections.
- Vegan progress: We promote plant-based eating and work with farmers to transition from farming animals to growing plants so fewer animals are bred into this system in the first place. Every vegan meal is a direct rejection of VSD+ and the mindset that makes it possible.
How you can take a stand
You have more power than the industry wants you to believe. Here’s how to use it:
- Support Animal Outlook’s work: Donations fuel investigations, legal cases, and corporate and consumer outreach.
- Stay informed and speak out: Share this blog, follow Animal Outlook on social media, and talk about VSD+ and depopulation with your community.
- Commit to a vegan lifestyle: Shifting what’s on your plate is one of the fastest ways to cut demand for a system that plans mass killing into its “emergency response.”
Together, we can rewrite the rules
The AVMA’s depopulation guidelines reveal a hard truth β our current food system is prepared to institutionalize suffering and externalize the costs. Animal Outlook is here to say: that’s not inevitable, and it’s not acceptable.
Thank you for standing with us β for believing that compassion is strength, that truth matters, and that animals deserve more than a contingency plan. With your support, we will keep exposing cruelty, challenging the status quo, and building a future where justice and innovation leave VSD+ and “depopulation” in the past.
