Amylase
Horses produce amylase in their salivary glands and pancreas. When a horse eats, the salivary glands release amylase into the mouth, where it begins to break down complex sugars in the food. This process helps to pre-digest the food before it reaches the stomach and intestines, where the rest of the digestive process takes place. The pancreas also produces amylase, which is released into the small intestine to continue the process of breaking down complex sugars
