Dr Ryan Duffy: 'I strongly believe our dairy industry is the envy of the world, and our continued success will be built on furthering our commitment to progressive herd health.'
Dr Ryan Duffy has been appointed as the programme manager for the Animal Health Ireland (AHI) CellCheck Programme.
In this role, Mr Duffy will lead and coordinate the national mastitis control programme, supporting continued improvements in udder health and milk quality across the Irish dairy sector.
A native of Co Monaghan, Mr Duffy qualified as a veterinary surgeon from UCD in 2016. Over the last decade, he has worked in clinical practice in both Ireland and New Zealand.
He has also held several influential industry roles and completed postgraduate qualifications in dairy herd health, ruminant nutrition, milking machine technologies, and veterinary education. He will take up his new role with AHI at the end of March 2026.
Mr Duffy said: “I’m hugely excited to join AHI at this really important time for the organisation and the dairy industry as a whole. In particular, leading CellCheck, our national mastitis control programme, is a tremendous honour for me.
"I strongly believe our dairy industry is the envy of the world, and our continued success will be built on furthering our commitment to progressive herd health, preventative medicine and by implementing practical, evidence-based methods for mitigating bovine mastitis and its knock-on effects.”
Animal Health Ireland chief executive Patrick Donohoe, said: “We’re very excited to see Ryan take up the role with AHI next month. Not only is Ryan an incredibly talented vet, but he is also an authority in herd health.
“…The CellCheck Programme has been one of the most successful animal health programmes anywhere in the world over the past 15 years, delivering real and tangible benefits for farmers and the wider dairy industry.”
