Our Story

At the heart of Alltech is an entrepreneurial journey.

In the 1970s, our founder and president, 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.

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.
