The death has been announced of Dr Pearse Lyons, the president and founder of animal nutrition company, Alltech.
A statement from the company said Dr Lyons died of an acute lung condition that developed during his recovery from heart surgery. He was 73.
Alric Blake, CEO and treasurer of Alltech, said Dr Lyons "was a visionary entrepreneur who transformed the agriculture industry beginning with his innovative application of yeast technology in animal nutrition.
"From farm to field, from market to family dinner table, our world is immeasurably better because he was a man who never saw problems, only a challenge that had not yet been solved.
"He inspired everyone he met with his energy, enthusiasm and passionate belief in possibilities. He instilled that positivity in his people, more than 5,000 Alltech team members around the world."
Dr Lyons is survived by his wife and children.
As the company' director of corporate image and design, Aoife Lyons said she will continue to further her father's vision for Alltech's global presence and their shared commitment to philanthropy and community involvement.
"We are all deeply saddened by my father's passing," said Dr Mark Lyons, son, chairman and president of Alltech.
"He always focused on developing people, and he built an extraordinary team over the years. I know he had full confidence in his team to continue growing the company he built."
