New Research Confirms That Diet Can Help Manage Gastric Ulcer Syndrome

Equine Gastric Ulcer Syndrome (EGUS) can affect any horse. It can cause discomfort and may have a detrimental effect on behaviour and performance but new research has confirmed that a suitable diet can help to manage the condition, especially after veterinary treatment is stopped. 

EGUS refers to the ulceration of the horse’s stomach lining. Several factors, including nutrition, have been shown to increase the risk of ulcers occurring, particularly in the non-glandular (squamous) part of the stomach.  In horses that are actively exercising and training, the incidence of gastric ulceration has been reported to be up to 90% in some sub-populations. Whilst dietary and management changes are often recommended to help reduce the risk of EGUS they are also suggested in conjunction with or following veterinary pharmaceutical treatment. However, until now there has been little published work to confirm their benefit under such circumstances. 

The new research study on the effect of changing diet on gastric ulceration in exercising horses and ponies following cessation of omeprazole treatment was conducted by Nanna Luthersson (Hestedoktoren, a private practice in Denmark) and Coby Bolger (Horse1 Spain), with colleagues from the University of Madrid and Glasgow, in collaboration with SPILLERS® and the WALTHAM® Equine Studies Group. The study was presented at the International Colic Symposium on 20th July 2017. 

The study evaluated the effect of dietary change in combination with omeprazole treatment and after the cessation of treatment.  The 32 horses in this part of the trial had been diagnosed with significant equine squamous gastric disease (ESGD) and were in hard work. For the purpose of more accurate comparisons the horses were paired, according to the severity of their ulcers, their workload, management and original diet.  On a random basis one of each pair was assigned to a specified low starch, fibre-based diet consisting of their own forage alongside a restricted starch, high fibre, high energy cube (SPILLERS® HDF Power Cubes, which are commonly used in racing yards) and a high oil, low starch, chopped alfalfa based feed (WINERGY® Equilibrium® Growth) and the other stayed on their original diet.  All animals were scoped before, after the recommended course of omeprazole treatment and then six weeks after the omeprazole finished. 

The horses in the no diet change group improved significantly with the omeprazole but when the treatment was stopped many regressed. Overall, by the end of the trial they were not significantly different to when they had started. However, the horses in the dietary change group overall showed significantly improved ESGD scores, not only following the omeprazole treatment but also after the treatment had stopped. This showed that a change in diet was able to help maintain the beneficial effect of omeprazole even after the omeprazole was removed.  The study achieved an award in 2016 for research in horse welfare from the Fundación para la Promoción del Deporte Ecuestre, Spain. 

Clare Barfoot RNutr, the research and development manager at SPILLERS®, said: “This exciting work confirms what we suspected; that whilst appropriate dietary change can provide additional support to medical treatment for EGUS most importantly it can help maintain better gastric health post medical treatment.”  

Last year the British Equestrian Trade Association, in consultation with the Veterinary Medicines Directorate, introduced a new feed approval mark to help owners identify feeds suitable for horses and ponies prone to equine gastric ulcer syndrome (EGUS). Currently six feeds in the UK carry the BETA Equine Gastric Ulceration Syndrome (EGUS) Certification Mark includingWINERGY® Equilibrium® Growth and SPILLERS® Alfalfa Pro Fibre.
