Most horses eat hay and some form of concentrates a day, such as grain or pelleted feed. They generally get concentrates one to two times a day, with the amount and type varying with each horse.
The gastrointestinal tract in horses is designed to regularly be ingesting small amounts of food all throughout the day. Non-ruminant herbivores are designed to consume a high fiber, low starch diets by foraging throughout the day.
This unlike other herbivores, such as cows, sheep, goats, and deer, that chew their cud. A horse will produce 20-80 liters of saliva a day, to aid in the process of digesting.
The stomach also digests protein and regulates the food that passes into the small intestine. Once in the small intestine, more digestion of protein happens, in addition to simple carbohydrates and fats.
The colon works to absorb nutrients and water that comes with food through the digestive tract. Some of the most common causes for colic are excess gas build up in the colon, dehydration, parasites, excessive intake of sand, stress, changes in diet, blockage in the digestion track and too much grain intake.
Signs of colic include rolling, laying down, stretching, pawing, kicking, lack of fecal production, lack of interest in food and water, elevated heart rate and sweating. If your horse is showing any signs of colic, you want to notify your vet immediately.
While waiting for the vet to arrive, it is a good idea to walk your horse, as this stimulates gut movement and prevents any injuries from excessive rolling. A balanced diet and constant access to fresh water can help prevent colic in horses.
Since horses are herbivores, their diet largely consists of hay and grass. Horses also typically eat grain or other concentrates to help meet their dietary needs, and they also enjoy many types of fruits and vegetables as treats.
Horses have a unique digestive system and it is very important for them to maintain a proper diet in order for them to be healthy. Each horse is unique and will have a different feeding plan based on their age, weight, and exercise.
From time immemorial, they have been used as a source of food, transport, entertainment, and companionship. Although they can survive solely on grass, hay, and plants, people still have their confusion about whether they’re herbivores, carnivores, or omnivores.
Studies show that some species rely on others as their source of food, and some eat other animals. Unlike many other animals, horses rely on plants as their primary source of food.
Animals have different jawlines, and the shape of their skulls and teeth can tell you what dietary habits they’re inclined to. They also have big canines that make it easier to grip the flesh and cut through it quickly.
They follow their prey and get as close to them as possible, and they make a sudden sprint to attack them. A predator’s jaws are created in a manner that gives them a significant advantage when it comes to hunting.
Their jaws are equipped with sharp incisors and large canines that help in crushing and breaking down the fibers into digestible form. Most omnivores show the behaviors of stealth when it comes to hunting, but they are also able to forge, dig, browse, and gather plant material.
Herbivores have a totally different jawline as their bodies are adapted to eating only pure, raw plant material. They’re easily able to cut, nip through the gross, or hold on as they pull back at branches of trees.
Rabbits, mice, and cattle have different types of incisors that help them eat. Herbivores animals have some common traits like alertness and the ability to run very fast as it’s their primary way to survive.
They’re bred so that they’re able to run races, pull heavy loads, or jump high and give performances. The digestive system of horses is very well-equipped at turning grass into energy.
Since canines are mostly used for chewing and tearing flesh, horses aren’t equipped to do that. A horse’s stomach can hold a small amount and empty it quickly as it passes through their bodies at a rate of about 1 foot per minute.
Horse breeders provide them with alternative sources of energy like grains. The grain helps to give them a boost, which enhances their energy and makes them work harder.
Horses hold a great deal of water and mass that fills up their enormous gut. Meats and animal products go bad very quickly, and they have toxins that don’t always get destroyed by cooking.
Hence, consuming meat once or twice may not hurt them but doesn’t mean it is the perfect addition to a horse’s diet. Herbivores, including horses, have evolved in a way that they can graze continuously throughout the day.
But at times when pasture isn’t available around the year, there are a few alternatives that one can give to their horses. Grains are meant to supplement hay and prove to be a rich source of vitamins and minerals.
Did you know an average horse can drink up to 5-10 gallons of fresh water a day? An average horse needs to consume hay, which is about 2% of their body weight in one day.
The time, environment, conditions, and harvesting process all have a significant impact on the quality of the hay. When serving them feed, you should allow your horse to enjoy hay first before consuming rich, calorie-dense grains.
It is crucial to ration the amount of grain, based on how much your horse requires. Grain portions should be based on your horse’s weight and activity level.
If you’re giving your horse too little a quantity of grains, it means you’re depriving them of some essential nutrients that could be beneficial for them. Small, frequent meals help in recreating the sort of experience a horse will have in nature.
However, this may not be fulfilling for them as it would be better to feed them at least three times a day with a gap of 8 hours in between each mealtime. Consistent feeding helps horses feel used to the surroundings, and a lack of this could also trigger health issues and stress.
The herbivorous nature of horses, and them being the PRE animal, helps us understand some of their behaviors and traits. They are not omnivores. We can understand that when a horse encounters danger, their steady response is to flee from the situation.
They’re equipped with speed and alertness, which helps them avoid risk and understand when they’re facing danger. Some studies have also shown that due to the fear of predators, prey chooses to live together in groups.
Equine digestive systems are incredibly delicate and are best suited for plant matter and not meat. Their jaws are designed in a way that helps them to grind and break down complex fibers instead of flesh.
Since they cannot vomit, toxins from these foods can build in their systems, which can prove to be fatal. Equestrians are also abuzz about the book Deadly Equines: The Shocking True Story of Meat-Eating and Murderous Horses.
We tend to organize everything into neat, tidy categories in our minds, so anything that deviates from the norm seems exciting. While many of these stories in Deadly Equines should be taken with a grain of salt, there is no denying meat is not off the table for horses (pun intended).
Viral videos of a horse eating a chick and a deer eating a bird, as well as the news story of deer scavenging on human corpses at a body farm in Texas, have understandably made a lot of people curious about what is going on. There are also omnivores that eat a little of everything and autotrophs, like plants and algae, that produce their own food.
In general, herbivores have flat teeth for grinding and long digestive systems, carnivores have sharper teeth for tearing meat and shorter digestive systems, and omnivores are somewhere in between. Lean, Mean, Green-Processing Machines The equine digestive system is excellent at turning grass into energy.
Horses teeth continually “erupt” throughout their life, as they are worn down from chewing tough plant matter. Ruminants, like cattle and sheep, use bacteria in their Rubens, a digestive chamber before the stomach, to ferment plant fiber.
In fact, horse stomachs hold a surprisingly small amount, empty quickly, and food passes through their bodies at a rate of about 1 foot per minute. Humans sometimes provide horses with alternate sources of energy, like grain, to give them a boost for harder work.
A typical 1,000-pound horse that is just working on maintaining her body condition needs roughly 15,000 calories a day. A lush, green pasture averages 245 calories per pound, so you can see why horses can spend up to 17 hours per day grazing.
So, how come horses can’t simply eat less food overall if it has a higher calorie and nutrient density? Besides providing energy and nutrients, all of this roughage holds a great deal of water and the sheer mass fills up the horse’s enormous gut.
When a horse’s digestive tract is empty, they are more prone to twisting of the intestines and colic. They can also lose their water reservoir and develop diarrhea, which can result in dehydration.
Since horses were made to be constantly consuming forage, they aren’t set up to handle the feeling of an empty stomach, and they are not sure what to do with all that time they spend not chewing. This can result in sand colic, where the desperate horse spends time sweeping the surrounding ground in an effort to relieve hunger and boredom.
Horses may also turn to chewing wood or other vices like cribbing and weaving. If they were to consume something dangerous or poisonous, it would require prompt veterinary attention.
Sure, they “can” process meat and get some energy and nutrients from it, but they have teeth that need grinding and a belly that needs to be kept full of fiber. The occasional snack of a bit of hot dog or slow chick with poor decision-making probably will not hurt them, but meat cannot be the foundation of a horse’s diet.
If horses are herbivores with a digestive system meant for plants, why are some of them eating meat? Many hooked animals, like cows and deer, are known to eat bones or antlers and some science points to a need for calcium as an explanation for this behavior.
Horses may eat sand, wood, manes/tails, and manure due to boredom or inadequate nutrients. Due to horses willingness to try different foods, they have been fed meat and animal products all over the world throughout history.
While horses in Iceland are generally kept on pasture, in the winter with supplemental hay, farmers may also place barrels of salted herring out for them. Exploration of Antarctica in the early 1900s made use of Siberian and Manchurian ponies to transport supplies.
These ponies were said to have eagerly eaten dried fish, blubber, and raw seal meat. Multiple reports of Tibetan horses from the 1800s through the 1900s said they were fed meat regularly and ones trained to eat it were more valuable.
Lawn clippings can contain dangerous chemicals or weeds that the horse cannot pick out. Horses also have a tendency not to chew clippings, which can lead to choke, colic, or laminates.
Horses are lactose intolerant and dairy products run the risk of causing digestive upset. Like other safe fruits they should only be given as a treat and not make up a large part of their diet.
Meat does not have the correct nutrients to make up a significant portion of their diet. Apple seeds produce hydrogen cyanide when chewed, which can be deadly in high enough doses.
Carrots make an excellent treat, but should only be given in moderation since they do not contain the correct nutrient profile for horses to stay healthy. Horses have herbivore digestive tracts and don’t need meat to survive.
In fact, they require ample plant matter to stay healthy. Horses may need up to 12 gallons of water per day, depending on their diet and environment.
(Source) Some horses might avoid drinking dirty, icy, or strange tasting water, and they run the risk of developing impaction colic. Keep your horse’s water clean, easy to access, and at a reasonable temperature.
What horses DO require is plenty of good quality roughage and clean water to keep their digestive systems running smoothly. Some typical mammalian omnivores include raccoons which are one of the best examples of an opportunistic feeder.
Wolves, cougars, owls, sea lions and walruses are examples of carnivores, while koalas, pandas, gazelles, zebras and caterpillars are herbivores. Herbivores are primary consumers and can include mammals, reptiles, insects, and birds.
Herbivores (such as deer, elephants, horses) have teeth that are adapted to grind vegetable tissue. All herbivores have unique physical features that adapted to feeding and digesting fibrous plant matter.
Our large collection of science worksheets are a great study tool for all ages. Herbivores (such as deer, elephants, horses) have teeth that are adapted to grind vegetable tissue.
A lesson PowerPoint and activity to meet the year 1 objective: That is why omnivorous animals are capable to behave sometimes like herbivores and sometimes like carnivores. Rabbits have a complex digestive system that allows them to extract as many nutrients as possible from the food they ingest, rhinoceroses.
The names of animals that are omnivores include humans, bears, badgers, hedgehogs, raccoons and squirrels. Identify and name a variety of common animals including fish, amphibians, reptiles, birds and mammals.
Omnivores get energy and nutrients from eating a diet containing plants, animals, algae and fungi. Due to the large variety of food options, they will eat what they can hunt and scavenge in their environment to make the most of what is available.
Carnivores eat meat (and other animal tissue) to get the calories and energy to survive. Carnivores find their food through predation or scavenging, and are often adapted with big claws, sharp teeth/beak and quick speed whether on land, in the sea or in the sky.
Plant vegetation, however, is very hard to break down into energy so most herbivores have a specialized digestive system. This part-digested grass is called cud It is then swallowed into third and fourth stomachs where the nutrients are absorbed into the blood.

The answer is not so simple, but to understand how we might’ve been led astray, it helps to explain the science behind the omnivore “dogma.” To that end, here are three points in favor of the canine-as-omnivore theory: Plant material is more difficult to break down, so herbivores have much longer intestines.
The story goes that the dog’s wild ancestors ate plenty of grains. It’s said not only that wolves will indulge in the occasional berry but that they’ll binge on grains contained within their prey’s stomach too.
It was recently found that dogs are different from their wild cousins in that they have three genes related to starch and glucose digestion. As such, it’s hard to deny that dogs are especially adapted to eating grains and other vegetation.
Given these fine points, it makes sense that we might rightly consider a dog an omnivore. But when comparing animals' gastrointestinal systems, it might be best not to think about length, girth, volume, capacity or any of that.
It might be more appropriate to look at a metric called the “coefficient of fermentation.” Herbivores have a high ability to extract nutrition from plant matter as the result of their ability to ferment it, and therefore have a high coefficient of fermentation. Interestingly, the coefficient of fermentation is similarly low in both dogs and cats.
