Keith Cutler has been a vet for over 30 years and currently works in cattle practice around Somerset, Dorset and into Devon. He is a diplomat of the European College of Bovine Health Management and a Royal College of Veterinary Surgeons-recognised specialist in Cattle Health and Production. His interests in the bovine field are many and varied. As well as suckler cow health, welfare and productivity, they also include the diagnosis, management and, where possible, eradication of endemic single-agent infectious diseases that affect our national herd, particularly BVD, Johne's disease and, of course, tuberculosis.
