The survey of 50 equine vets, which was conducted in May this year, showed that the number of practices owning a scope has more than doubled over the past six years. Half of equine practices now own a scope. Over the same period the average number of monthly scopes has risen from 1.5 to 9.25 and referrals from practices without a scope has risen by 65%.

Merial's Louise Radford MRCVS said: "The survey also showed that symptom recognition among vets prompting the need for an endoscopy has also risen. The vast majority of vets now consider changes in behaviour, loss of appetite and poor performance as potential signs. In addition, 100% of those surveyed would consider an endoscopy when presented with the signs of recurring colic.

"However whilst this is great progress, when diagnosis is compared to the incidence of ulcer, we know that more needs to be done. It is believed that up to 30% of leisure horses have some degree of gastric ulceration, and this increases in sports horses, yet just a fraction of this figure represents those scoped."

Richard Hepburn BVSc MS(Hons) CertEM(IntMed) DipACVIM(LA) MRCVS, American and RCVS Specialist in Equine Internal Medicine at B&W Equine Hospital says he is pleased that more horses are being scoped for gastric ulcers but says that further education is needed: "We've seen a huge leap in the appreciation of the incidence of gastric ulceration in non-racing animals, which long term will better our understanding of the individual clinical relevance of particular lesions, and the benefits of treatment and management change.

"This should improve both performance and horse welfare, as well as increasing client satisfaction. Despite the huge increase in the diagnosis and treatment of equine gastric ulcers it is still believed that many horses go undiagnosed."
