Horses have a fascinating and unique digestive system that requires careful attention. As non-ruminant herbivores, horses thrive on forage-based diets and have a single-compartment stomach—similar to humans. Since horses are hindgut fermenters, they also rely on fermentation in their hindgut (cecum and colon) to extract energy from forage. 🌾
🔬 How it Works:
1️⃣ Chewing (Mechanical Digestion):
Digestion starts in the mouth, where chewing breaks food into smaller pieces, increasing the surface area for digestive enzymes. Chewing also produces saliva, which buffers stomach acid and supports gastric health. Horses with dental issues may struggle to chew, so their diet may need to be adjusted. 🦷💧
2️⃣ The Stomach (Chemical Digestion):
In the stomach, gastric acid, enzymes, and microbes continue breaking down food. The stomach’s acidic environment helps digest food and defends against harmful microorganisms. However, since horses continuously produce stomach acid—even when not eating—long periods of time without food (forage) can increase their risk of ulcers. 🧪🍴
3️⃣ The Small Intestine (Nutrient Absorption):
After the stomach, digesta moves to the small intestine, where enzymes continue to break down the food even more. Nutrients like starch, protein, and fats are absorbed. 🌟
4️⃣ Hindgut Fermentation (Cecum & Colon):
In the hindgut, microbes ferment fibre from hay, pasture, and other forages, producing volatile fatty acids (VFAs) which are a major energy source for horses. Any undigested food continues through the colon, where water is absorbed, and waste is formed. 🌾🔥
