Hindgut is made up of large Intestine comprised of Cecum and Colon.
But in the hindgut of the horse, billions of bacteria and other micro-organisms ferment the structural carbohydrates that constitute fibre and convert them to Volatile Fatty Acids that the horse can digest.
Volatile Fatty Acids (VFA) acids are the primary source of energy for the horse.
Due to the presence of less fibre in their diet, and the presence of fed concentrates such as processed grain and pellets are the primary reasons for the hind gut ulcer. Due to the presence of the loose hay in the diet, to encourage chewing and salivation, the rapid ingestion of concentrates allows these to reach the hindgut undigested.
Microorganisms in the cecum and colon transform a portion of these high-energy feeds and starches into lactic acid, which are the reason for the hind gut acidosis. This acidic environment shifts the equilibrium of normal microorganisms and pathogenic bacteria, which causes an inability to ferment forage into Volatile Fatty Acids and thus leads to hindgut ulcers in horses
Symptoms of Hindgut Ulcers in Horses
Horses show signs that include unexplained performance, weight loss and colic. Horses also have an unthrifty appearance and mild diarrhea. In foals, suffering from ulcers teeth grinding and excessive salivation are common.
Scoping will not show the presence of hindgut ulcers in horses, treatment with sucralfate will show sign of improvement in your horses demeanour in less than 7 days of treating.
Sucralfate is a cytoprotective agent for the symptomatic treatment of equine gastric ulcer syndrome, small intestine, hindgut and colonic ulcers (right dorsal colitis). When sucralfate is administered in conjunction with omeprazole, sucralfate will coat the ulcer which avoids further acid damage and allows the omeprazole to treat the cause.
