Ulcers are so prevalent in horses with vet journals stating that 60-80% of horses suffer. The causes are well documented and include stress and insufficient food/forage over periods. Equally, the causes of stress are known. Separation anxiety and isolation, travelling and competition, home/environment and management changes, weaning and castration.
What are ulcers exactly? An ulcer is an open sore on the skin or the lining of an organ or tissue that occurs when an area becomes inflamed, dies, and sheds.
Horses most commonly develop gastric ulcers in the stomach, which is divided into two anatomical regions. Ulceration severity and cause depend on which of these two specific sites is affected. The Squamous Region (Non-glandular) accounts for approximately 80% of equine gastric ulcer syndrome (EGUS) cases. This upper region of the stomach lacks protective glandular linings and is highly susceptible to acid burns. The Margo Plicatus, (the jagged line separating the squamous and glandular regions) is the most common single site for ulcer formation.
The Greater Curvature of the stomach, is also known for "splash ulcers", caused by intense exercise or movement that forces acidic fluid upward into the vulnerable upper lining.
The Glandular Region, accounts for roughly 20% of cases. This lower section produces hydrochloric acid and is equipped with protective mucous and bicarbonate layers. Ulcers occur when these natural defense barriers break down, rather than from simple acid exposure. Ulcers can also develop in the lower esophagus or the entrance of the duodenum, the first part of the small intestine.
The question is: Why, if the cause is known,
would you not empathise? Show compassion and understanding, and do everything in your power to prevent.
Anyone who has experienced ulcers or the pain of indigestion and acid reflux and had to take PPIs, must surely ask themself if they would wish to attend an event or travel, that provoked pain and discomfort.
Whether they would be prepared to be deprived of food for long periods and confined to a small room, the equivalent of a lift/ elevator, or a small cupboard, providing just enough space for basic movement but not much more for 8, 10, 12 hours. Some never leaving other than to get a couple of hours of exercise before being returned to their confinement, for the sake of their sport.
So again, why?
