A high prevalence of both squamous (ESGD) and glandular (EGGD) ulcers was previously found in, mainly young, Icelandic horses coming into training for the first time. This study evaluated risk factors for gastric ulcers in Icelandic riding horses at various ages and stages of training. The horses (n = 211) were gastroscoped from 21 equine establishments across Iceland.

Animals: 81 horses (median age, 3 years; interquartile range, 1 year) from 10 farms representing 4 different Icelandic regions.
Procedures: Initial gastroscopy was undertaken within 2 weeks of moving from pasture into a training establishment.
Free faecal water (FFW) in equines results in pollution of the hindquarters and tail and can also involve clinical signs. Though the cause of FFW is unknown, it was hypothesized that it may involve the gut microbiota. This hypothesis was addressed as follows.

Previously, in a field study, straw was associated with an increased risk for gastric ulcers. This study evaluated the effect on gastric ulcers, metabolic profile and behaviour of replacing, in a forage-only ration, 50% of the daily allowance with wheat straw.

- Diet is a known risk factor for equine squamous gastric disease (ESGD), and this study aimed to assess the effectiveness of dietary changes either with or without omeprazole medication in affected horses.
- The study involved 12 exercising horses graded 2/4 for ESGD and 17 graded ≥3/4, with pairs monitored under similar conditions and randomly assigned to either a restricted starch diet or their original diet.
- Results showed that while both groups experienced improvements over time, those on the dietary change showed significant long-term benefits, indicating that dietary adjustments can be a useful management strategy for ESGD despite the small sample size.
The horse is a non-ruminant herbivore adapted to eating plant-fibre or forage-based diets. Some horses are stabled for most or the majority of the day with limited or no access to fresh pasture and are fed preserved forage typically as hay or haylage and sometimes silage. This raises questions with respect to the quality and suitability of these preserved forages (considering production, nutritional content, digestibility as well as hygiene) and required quantities.

However, there have been few studies to confirm these findings in nonracehorses in Europe.
Objectives: To investigate the prevalence of EGUS in a population of Danish horses, during winter when the horses had been housed and fed for at least 8 weeks and to analyse the influence of feed, work level and environment on the risk of EGUS of > or = grade 2 in severity.
Reasons For Performing Study: The prevalence (up to 93% in Thoroughbred racehorses) and severity of equine gastric ulceration syndrome (EGUS) have been correlated with the type of training and associated management practices. However, there have been few reports to confirm these findings in nonracehorses in Europe.
Objectives: To describe the prevalence, anatomical distribution, severity and number of gastric ulceration lesions in a population of Danish pleasure horses; and to investigate differences for groups based on age, breed type and workload.
