KEEPING ANIMALS HEALTHY
Hi I'm Tommy The Vet
thanks for visiting my website
I'm Tommy Heffernan — a vet with over two decades of experience in animal health, and one of Ireland's leading voices in gut microbiome science.
I work with farmers, vets, feed companies, and animal health businesses across Ireland, Europe, and international markets. My work sits at the intersection of veterinary science, biological innovation, and practical farm performance.
I am the Veterinary Consultant and Head of Technical and Brand Development at Precision Microbes — an animal health biologics company developing the next generation of biological solutions for livestock and equine health.
This is where I share what I know. If you want to work with me, get in touch.

Help Make Farming Better
For over two decades, animal health has been my life's work. From running a busy mixed-animal practice in Co Wicklow to consulting across international markets, I've always believed that the best farm advice is simple, science-based, and grounded in the reality of daily farm life.
My focus now is on the gut microbiome — the most important and most underutilised lever in animal health today. The science is clear: a healthy gut means a healthier, higher-performing animal. Through my work with Precision Microbes, I'm helping bring that science to farms and animal health businesses around the world.
"The gut is where animal health begins. Get that right, and everything else follows."<br />
Tommy Heffernan, Tommy The Vet
The goal has never been to treat sick animals — it's to keep healthy animals healthy. That principle has driven everything I've done as a vet, and it's more relevant now than ever.
The gut microbiome sits at the centre of that. When the microbiome is balanced and thriving, animals are more resilient, more productive, and less reliant on medicines. When it's disrupted, performance suffers and disease follows.
My work with Precision Microbes is focused on harnessing that science — developing biological products that support gut health from the ground up, across all species and all stages of life.
