Mars Veterinary's 2025 Science Report Drops 500+ Studies That Could Change Your Practice

When a company publishes over 500 peer-reviewed studies in a single year, you pay attention. When those studies are drawn from data on millions of pets treated annually across a global network, you really pay attention.

Mars Veterinary Health just released its 2025 Science Impact Report, and the scale alone is staggering. This isn't a handful of academic papers collecting dust in obscure journals. This is real-world clinical data from 70,000 veterinary professionals across North America, Europe, and Asia, turned into actionable research that's already shaping how we practice.

What's Actually in There

The report covers the full spectrum of what we see daily: oncology, neurology, anesthesia, dermatology, infectious disease, and more. But it's not just breadth. There's depth here that matters.

Take Owner Reported Outcomes, or OROs. Mars Veterinary has developed rigorously validated instruments that systematically incorporate pet owner perspectives into clinical care and veterinary trials. If you've ever struggled to quantify treatment success beyond clinical parameters, this is a tool designed specifically for that gap. It's the first globally standardized way to assess pet well-being and treatment response from the owner's viewpoint.

Then there's the Access to Veterinary Care framework. Working with Michigan State University, Mars established the first metrics and framework for measuring A2VC. That matters because until now, we've been having passionate debates about access to care without consistent ways to measure it. Now we have baseline metrics that enable actual research and policy development instead of anecdotal arguments.

The One Health Angle

The One Health research is where things get particularly interesting. Mars teams identified a novel rabies variant in the U.S. and detected a human erythroparvovirus analogue in cats in Italy. They're studying mercury exposure in veterinary practice and tracking greenhouse gas emissions. This isn't feel-good corporate responsibility content. This is research that connects veterinary medicine to public health in ways that actually matter.

The pharmaceutical stewardship studies alone reached millions of people worldwide. When we talk about combating antimicrobial resistance, we need data at scale. Mars is providing it.

What This Means for Your Practice

Here's why this report matters beyond impressive statistics: The research is coming from clinicians working in general practice and specialty hospitals. These aren't ivory tower academics studying theoretical problems. These are veterinarians seeing the same cases you're seeing, asking the same questions you're asking, and now they have the resources and data infrastructure to actually find answers.

The Medical Affairs Science Team that Mars established leverages anonymized data from millions of annual pet visits. That dataset allows for research that simply isn't possible at smaller scales. Database research projects can generate insights quickly enough to be relevant to current clinical challenges, not just historical curiosities.

The Bottom Line

500+ peer-reviewed publications in one year. Owner Reported Outcomes that give us better tools to measure treatment success. Access to care metrics that turn passionate debates into researchable questions. One Health breakthroughs that connect veterinary medicine to broader public health challenges.

This isn't just Mars showing off what they can do with their resources. This is a blueprint for what veterinary research can look like when you combine scale, data, and clinical expertise.
