Our Story


At the heart of Alltech is an entrepreneurial journey.

In the 1970s, our founder, Dr. Pearse Lyons, immigrated to the United States with a dream: to sustain our planet and all things living on it. As an Irish scientist, he saw an opportunity to apply his yeast fermentation expertise to animal nutrition challenges, and his dream became a reality when he founded Alltech in 1980 with just $10,000.

Today, a global team of more than 6,000 people around the world shares this vision of sustaining and nourishing the world’s plants, animals and people.

We deliver on this vision by improving plant, feed and food quality through nutrition and scientific innovation, particularly yeast-based technology. Our team is fully committed to helping plants and animals achieve their full potential while supporting producers in greater efficiency, profitability and sustainability.

Starting with the soil


At Alltech Crop Science, growth is natural with us.

We provide natural-based products and solutions to agronomic and horticultural challenges facing producers across the globe, addressing the production of citrus, silage and everything in between.

Our goal is to seamlessly bridge the gap between science and sustainability. By sharing our expertise, providing constant technical support and exploring the intricacies of each region we serve, we are not only pursuing greater productivity, profitability and sustainability for every crop — we are working alongside producers and agronomists to build the future of agriculture.


Focusing on the feed…

Through our innovative study of nutrigenomics, our nutritional technologies help animals maximize the nutrients in their feed for optimal well-being and performance.

We work with producers across the globe to address the animal nutrition issues most important to them, including:


...and the farm

Alltech’s support goes beyond nutrition. We partner with producers to increase their efficiency, productivity and profitability through analytical services, including:

  • Alltech IFM to analyze the feed ration
  • Alltech 37+ to quantify mycotoxin risk
  • Alltech E-CO2 to assess on-farm efficiency and sustainability



We bring traceability, quality and improved nutrition to the table.

As a family company, we understand the consumer’s desire to ensure that their family’s meals are as safe and nutritious as possible. From our innovative use of organic minerals to our work in crop science, we focus on improving nutrient value throughout the food chain.

Our guiding principle

In all of these endeavors, we are guided by our ACE principle, our promise that in doing business we have a positive impact on the Animal, Consumer and Environment.
