Mark Bryan

Mark Bryan is a veterinarian, landlord and researcher working in New Zealand. He is a director of VetSouth, one of two clinical research clinics in the South Island and Adjunct Senior Lecturer in Dairy Cattle Medicine at Massey University. In 2013 he was a finalist in the Ernst & Young Entrepreneur of the Year. He is a board member of the New Zealand Veterinary Association. In 2004 gained his Masters in Epidemiology from Massey University in Palmerston North. Bryan moved to New Zealand in 1995 and to his current practice in 1997.

He joined Central Southland Vets in Winton in 1997, heading up the dairy side of the practice, then became a director in 2001. When the clinic merged with another in nearby Gore in 2005, Bryan became the managing director of the new entity. He aimed to tackle the challenge of attracting and retaining in-demand veterinary school graduates, as well as participating in research.

Bryan's veterinary service created an app called Disease and Mortality Incident Tracker, or dam-iT, to capture disease and mortality data in production animals. It aims to provide a baseline of normal mortality rates on New Zealand farms as there are no national disease statistics. Creation of the app was partly prompted by deaths on herbicide tolerant swedes and fodder beet in 2014 and following years.

VetSouth has been running the Welfarm pilot for 3 years and identified the use of antibiotics as an issue to address. The New Zealand Veterinary Association has recently announced that they are aiming to phase out the use of non- essential antibiotic usage by 2030. Their strategic intent is that “by 2030, NZ Inc would not need antibiotics for the maintenance of animal health and welfare”.

Bryan is active in the veterinary and general communities promoting animal welfare and good veterinary practices. and in promoting the welfare of veterinarians in general. He spoke at the 2015 Pan Pacific Veterinary Conference and at the NZ Skeptics Conference in 2016. Bryan was to be a Dairy Speaker at the 36th World Veterinary Association Congress in Auckland, New Zealand on 6–8 April 2020, which was cancelled at the outset of the COVID-19 pandemic.
