Topic:Gastrointestinal Health
Gastrointestinal health in horses encompasses the study of the structure, function, and disorders of the equine digestive system. The equine gastrointestinal tract is complex, consisting of the stomach, small intestine, cecum, and large intestine, each playing a specific role in digestion and nutrient absorption. Research in this area often focuses on common disorders such as colic, gastric ulcers, and parasitic infections, which can impact a horse's overall health and performance. Investigations examine factors affecting gastrointestinal health, including diet, management practices, and the microbiome. This page compiles peer-reviewed research studies and scholarly articles that explore the physiology, pathology, and management of gastrointestinal health in horses.
Electromyoenterography during normal gastro-intestinal activity, painful or non-painful colic and morphine analgesia, in the horse. The electrical potentials were recorded from the antrum, the duodenum, the ileum and the first part of the colon of ponies under (a) normal resting conditions, (b) during nonpainful colic and (c) after intravenous morphine administration. The normal pony, at rest, had five contractions of the antrum per minute. On the small intestine, the basal electrical activity decreased from the duodenum (14-15/min) to the ileum (10-11/min). The small bowel also had three types of motility: peristaltic waves, rhythmic segmentations and random contractions. On the colon, bursts of potentials indicating inte...
Site of phosphorus absorption from the intestine of the horse. The site of phosphorus absorption was studied by comparing the absorption of 32P placed directly into the cecum of fistulated ponies, with that absorbed from an intragastric dose and by estimating apparent absorption in different areas of the intestinal tract of ponies using Cr2O3 as an unabsorbable marker. There was no difference in the absorption of 32P following gastric or cecal administration indicating that phosphorus may be absorbed from the large intestine. The Cr2O3/nutrient ratio technique indicated that phosphorus was secreted into the upper half of the small bowel and that a nearly ...
Apparent digestion in various segments of the digestive tract of ponies fed diets with varying roughage-grain ratios. Eleven ponies were fed diets containing 1:0, 3:2 or 1:4 forage-grain ratios for 30 days. Animals were killed 4 hr. after feeding and the entire digestive tracts were removed and segments isolated. Digestion coefficients were calculated for dry matter, protein, available carbohydrate (ACHO) and neutral detergent fiber (NDF) by Cr2O3-nutrient ratio for seven segments of the gut.
The major site of ACHO and protein digestion was prececal; whereas, the major sites of NDF digestion were the colon and cecum regardless of the hay:grain ratio. Therefore the relative importance of digestion in the lo...
