Horses do not produce saliva to break down food. Instead, saliva moistens and lubricates food, making it easier to swallow. While human saliva contains amylase, an enzyme that initiates the digestion of starch, the saliva of carnivores like cats and dogs doesn’t have amylase because their natural diet contains very little starch.
Does Saliva Help Horses Break Down Food?
Saliva moistens and lubricates food, which eases the passage of food through the digestive tract. Chewing also reduces food to smaller particles, further assisting digestion.
How Does Chewing Aid Digestion?
Chewing is the initial mechanical process in digestion, reducing food into smaller particles and mixing it with saliva. Although mastication isn’t essential for digestion, it helps by breaking down food and mixing it with saliva.
What Role Does Saliva Play in Digestion?
Saliva moistens and lubricates food, making it easier to swallow. In humans, saliva contains amylase, an enzyme that starts breaking down starch into maltose. However, the saliva of some animals, like dogs and cats, lacks amylase because their diets contain minimal starch.
What is the Digestive System of a Horse Like?
Horses have a simple, small stomach that makes up only 8.5% of their entire digestive system. Their intestine is very long, and the cecum and colon are large, where food is macerated, fermented, and fibrous portions are dissolved.

Does a horse’s diet affect its saliva?
Yes, the composition of saliva can vary based on diet. For instance, animals with starch-rich diets, like humans, have amylase in their saliva to help break down starches. However, animals with low-starch diets, such as cats and dogs, lack amylase in their saliva.
How does saliva protect the mouth?
Saliva keeps the mouth moist and free from food residues, sloughed epithelial cells, and foreign particles. It also inhibits bacterial growth and contains lysozyme, an enzyme that dissolves certain bacteria, providing a protective function.
What happens if saliva is absent?
Without saliva, the oral mucous membrane becomes dry, leading to poor oral hygiene due to bacterial overgrowth. A diminished sense of taste and difficulties with speech may also occur.
In summary, while saliva doesn’t necessarily break down food in horses, it does play a crucial role in moistening and lubricating food, which aids in swallowing and overall digestion.
