What Animals Eat Grass? [17 Explained]


Animals that eat grass are known as “Herbivores“. Grasses are the dominating vegetation in the majority of forage-based industries around the world. Grass may appear harsh and unappealing, but it provides numerous nutritional benefits to herbivores. It is high in fiber, which aids digestion, and it provides critical nutrients such as carbs, proteins, and numerous vitamins and minerals.

Herbivores are animals that eat mostly plants. Unlike carnivores who consume meat or omnivores which consume both plant and animal materials, herbivores have evolved to obtain nutrition and energy from plant-based sources.

What Animals Eat Grass? Grass is the primary food source for all herbivores. Grass is eaten by many sorts of livestock such as camels, pandas, pigs, giraffes, rabbits, elephants, cows, buffalo sheep and goats. Other animals that consume grass include elk and deer. Cow, Buffalo, Sheep, and Horse are the best examples of grass-eating animals in my opinion.

In the next sections, we’ll uncover the complexities of the herbivore-grass interaction, as well as the fascinating ways in which these creatures adapt, consume, and modify their habitats. So, let us look more closely at each of these grass-eating animals.

List Of 17 Herbivorous Animals That Like To Eat Grass:

Here’s are 17 herbivores that like to eat grass:

  1. Cows
  2. Horses
  3. Sheep
  4. Goats
  5. Elephants
  6. Giraffes

  12. Zebra
  13. Camels
  14. Yak
  15. Antelope
  16. Hippos
  17. Moose

These are just a few examples of animals that consume grass as a significant part of their diet.

1. Cows:

Cows eating grass

Do Cows consume grass? Cows must eat grasses since grains are considerably too rich. However, cows may survive quite nicely on grasses alone. Grass-fed meat is both healthier and more flavorful than grain-fed steak. These herbivores are important to agriculture because they provide dairy products and meat to people.

Farms animals that eat grass like wild cows. They are among the most well-known grass eaters. They are ruminant mammals which means they have a strong stomach with four compartments that aids in plant digestion. Cows graze on a range of grasses, grinding down the stiff fibers using their strong and flat molars. They can obtain the most nutrients from the plant stuff by regurgitating and re-chewing their cud.

Why does a cow eat grass?

Because, it’s a complete diet. Cows get the most nutrition from grass because they have what is known as a “foregut strategy.” The rumen, one stomach, appears to be the size of a dustbin and is filled with fermenting grass. Heat and microorganisms cause it to ferment. This fermentation process is what feeds nutrients to the cow.

2. Horses:

Do Horse eat grass

Horses are big herbivores that have evolved to eat grasses as their primary source of nutrition. Their teeth are designed to chew down fibrous plant material, and their stomachs are quite basic, allowing for efficient digestion. Horses are classified as “hindgut fermenters,” which means that microbial fermentation of plant material takes place in their big intestine. This mechanism aids in the breakdown of cellulose a difficult-to-digest component of plant cell walls. Horses have played an important part in human history assisting with transportation, agriculture, and recreation.

Grass provides all of the nutrition for horses. Horses, like cows and sheep, consume grass and do not require any other sustenance. We feed them oats and grains, but these are not natural foods. Only grass can sustain horses and rumens (cows and sheep).

Why do horses eat grass?

Horses love natural grass. The key is in their distinct digestive system. Horses have a single-chambered stomach in which microbes painstakingly break down cellulose from grass, releasing important nutrients such as proteins and carbohydrates.

Basically, Horses require a higher-quality diet in order to grow muscle while still gaining fat. However, a diet that is overly rich will promote digestive disorders such as colic, as well as an apparently unrelated digestive issue such as founder. The more active a horse is, the greater his dietary needs. Furthermore, growing horses and nursing mares require extra calories and protein for growth and muscular development, as well as to provide milk for a foal (in addition to meeting her own physical nutritional requirements).

3. Sheep:

Does sheep eat grass

Sheep are ruminants, which are related to goats. Domestication is done for their wool, meat, and milk. Sheep have a complicated digestive system that allows them to feed on a wide variety of grasses and other food.

Does sheep eat grass? Yes. Sheep are grazing animals that enjoy eating green grass. Long grass is preferable for grazers to consume since parasites can only climb 3-4″ up the grass and if the animal eats higher than that, they aren’t consuming worms and are far less likely to become ill as a result of parasites.

Why do sheep eat green grass?

They have a four-chambered stomach that allows them to efficiently break down cellulose and absorb nutrients. Sheep are important in many cultures and have been bred for varied features such as wool and meat quality.

Sheep do maintain a lawn when eating grass. They have a natural instinct to graze evenly and will typically avoid overgrazing an area. This enjoy grazing in pastures and will consume almost any plant in them. This could comprise a variety of grasses, legumes (such as clover), and forbs.

4. Goats:

Do goat eat grass

Goats are well-known for their propensity to consume a broad variety of plant material, such as fresh grasses, bushes, and leaves. They are also ruminants with a digestive mechanism similar to sheep and cows. Because of their browsing activity, goats may survive in areas where other animals might struggle to find food. They are used for milk, meat, and fibers like as cashmere and mohair. Goats have become essential livestock in many areas due to their hardiness and flexibility.

Goats eat grass, grains, and hay, but they don’t enjoy it. They prefer weeds and bushy bushes. They’ll strip the bark off trees while standing in ankle-high grass. Many cattlemen would run goats alongside their cows to keep their pastures clear of brush and weeds.

Why do goats need grass?

Goats will graze on grass to supplement their nutrition, especially when stalky forages are scarce, although grass does not constitute a significant portion of their diet.

Goats are ruminant animals that ingest and digest vegetation in a four-compartment stomach. In terms of nutrition, they are more similar to deer than to sheep or cattle, who eat a lot of grass. Goats are well-known for their capacity to feed on a wide variety of plants, including fresh grass and woody bushes.

5. Elephants:

Do elephants eat grass

Especially African savanna elephants consume a lot of grass for their diets. While they are largely herbivores, their vast size necessitates that they consume a large amount of food on a daily basis. Asian elephants can eat three hundred pounds of foods in one day, they eat grass in the rainforest. Elephants uproot and gather grasses using their muscular trunks, which they subsequently devour with their molars. Their digestive system is intended to break down plant components like as grasses, leaves, and fruits. Elephants help to shape their habitats by building trails and clearings while foraging.

Why do elephants eat grass? Yes, grass is a very important part of their diet since it is high in fiber and other nutrients that elephants require. Elephants spend the most of their time in the wild feeding on grass and other vegetation. They pick up the grass with their trunks and munch it with their enormous molars.

Why do elephants eat grass?

They get nourishment, fiber, and energy from green grass. Elephants eat a lot of grass, which they get by breaking with their trunks and feet. They love eating grass and grazing on it when it is available. They eat grass of various sorts as they adapt to their local environment.

6. Giraffes:

Do girrafes eat grass

Giraffes are famous for having long necks that allow them to reach leaves high up in trees. However, grasses are an important element of their diet, especially while browsing at lower heights. Giraffes have unique tongues and lips that allow them to pull leaves and grasses into their mouths. They are ruminants with the ability to absorb nutrition from fibrous plant material.

Why do giraffes eat grass?

Can giraffes eat grass? Giraffes are primarily browsers (consuming foliage above ground in trees or shrubs) rather than grazers (consuming grass or other ground cover). They eat grasses for their diet, but not all time. But when they go graze or drink, they usually only spread their legs to get their mouths closer to the ground or water.

7. Bison:

bison eat grass

Bison are commonly associated with North American grasslands. They are another example of grass-eating animals like buffalo. They are well-adapted to grazing on broad plains, and their selective feeding behavior allows them to flourish on a variety of grass kinds. Bison once had an important role in structuring grassland ecosystems by influencing plant development and biodiversity through their grazing patterns.

In the forest wild, bison eat green grasses and sedges as well as berries, woody plants, and pretty much anything that is in season. In the winter, they use their huge heads and hoofs to clear snow from hidden vegetation.

Why do bison eat fresh grass?

They eat a lot of food preferring young grass that is high in protein. They have an additional stomach packed with microorganisms to aid with digestion. The Bison appear to ingest single celled organisms that dwell on grass called Protozoans when consuming grass. These protozoans then dwell within the Bison and degrade the stuff that the Bison consumes in order to produce proteins for themselves.

8. Deer:

Do deer eat green grass

Many deer species are herbivores that feed on grasses and other vegetation. White-tailed deer, for example, have been observed eating a wide range of vegetation, including grasses, leaves, and fruits like pumpkins. Deer play a vital role in ecosystems by dispersing seeds and influencing plant populations.

Do deer like to eat grass? Deer generally consume grasses, forbs (weeds), leaves, and, during the winter when grass and forbs are scarce, branches and even bark. It has been discovered that deer consume mushrooms as part of their diet. These sensitive herbivores consume a broad range of foods, including mushrooms foraged in the wild.

Why do deer eat grass?

Deer are classified as ruminants, a species of herbivore distinguished by its distinct digestive system. Ruminants devour a wide range of plant species.

Deer are categorized as obligate herbivores, which means they only eat plants. That is why they constantly eat grass and search for leaves, acorns, berries, barks, twigs, bushes, nuts, and flowers.

9. Rabbits:

Do rabbit like to eat grass

Rabbits are lagomorphs that primarily feed on grasses and other plant material. They have a unique digestive system that includes hindgut fermentation, where microbes in their large intestine help break down cellulose. Rabbits have a high metabolism and must constantly graze to meet their energy requirements.

They lagomorphs that eat grasses and other plant material. They have a distinctive digestive system that includes hindgut fermentation, in which bacteria in their large intestine assist in the breakdown of cellulose. Rabbits have a fast metabolism and must constantly graze in order to meet their energy needs.

Do rabbits eat grass? Yes, they consume various grasses and leafy greens, as well as fruits and vegetables. I’m not sure what to say about “why.” They are natural grazers and require it for optimal nutrition.

Why do rabbits like to eat grass?

Rabbit enjoy eating grass because it provides them with the vitamins and minerals they require to keep healthy. Their teeth are extremely sharp, and they utilize them to cut and rip the grass into small bits.

Grass is necessary for rabbits diet and health. They eat grass hay, which is rich in fiber. The recommended amount of hay in a rabbit’s diet varies, but most recommend 70-75%. Pellets and fresh green leafy vegetables are secondary but necessary components in a healthy house of rabbit’s diet.

10. Guinea Pigs:

Guinea Pigs

Guinea pigs are little rodents who eat fresh grass as part of their diet. In comparison to ruminants, they have simple stomachs and a basic digestive system. Grass gives them vital nutrients, fiber, and moisture.

11. Kangaroos:

Kangaroo Eating grass

Kangaroos are Australian marsupials that graze on a range of plants, including grasses. They have a distinct digestive system that helps them to obtain as many nutrients as possible from fibrous plant material. Kangaroos have become famous emblems of Australian nature due to their adaptation to arid settings.

Do kangaroos eat grass? Kangaroos are herbivorous animals. They also consume grasses, flowers, leaves, ferns, moss, and insects. They survive solely on plant matter. That being said, different kangaroo species have varied diets. Some species are mostly grazing animals that feed primarily on grasses.

12. Zebras:

Does zebras eating grass

Zebras are known for their distinctive black and white stripes and graze on grasses in their natural habitats, which include grasslands and savannas. They have adapted to consume tough plant material, and their digestive systems aid in breaking down cellulose.

The zebras are a fascinating species of the animal kingdom which possess an array of remarkable adaptations of zebras according to environment that enable them to survive in their diverse habitats.

Do zebras eat grass? They primarily eat grass, but can supplement their diet with shrubs, twigs, leaves, bushes, shoots, herbs, roots, fruits, and even bark. Grass accounts about 90% of a zebra’s diet. Obviously, the abundance of plants in the zebras’ habitat has a direct impact on their diet.

Why do zebras eat grass?

Zebras are herbivorous animals, which means they eat plants. They consume a lot of grass because it doesn’t have a lot of nutrients (but it has a lot of fiber). They can also devour the branches of small plants, tree bark, and small sprouts.

13. Camels:

What Animals Eat Grass

What animals eat grass in the desert? Camels thrive in arid regions and eat a range of desert grasses. They can take moisture from their food and store it in their humps, helping them to live in hard environments. Camels is often associated with arid desert landscapes might not like awesome swimmers but they do possess the surprising ability to swim when the need arises.

Does camel eat grass? Camels mouths are leathery, allowing them to eat any type of plant. They consume plants, dried leaves, seeds, and bones. They eat dates, grass, wheat, oats, hay, and dry grass in captivity.

Why do camels eat plants?

Because, camels diet in the desert must consist of whatever is available to provide the nutrition they require. As a result, they are opportunistic foragers capable to eating even thorny plants, such as goats. Their digestive processes enable them to consume roughage, allowing them to take advantage of the most abundant plants.

14. Yak:

Yak eat grass

Yaks are tough animals that graze on grasses and other flora in high-altitude areas like Himalayas. They are valuable livestock in areas where other animals may struggle to survive owing to adverse weather conditions.

Seasonally, they travel to the lower plains to feed on grasses and herbs. When it gets too hot, they move to higher plateaus to feed mosses and lichens that they scrape off rocks with their rough tongues.

15. Antelope:

Antelope eat grass

Various species of antelope, such as gazelles and impalas, are known for their grazing behavior. They inhabit grasslands and savannas and feed on grasses and other vegetation as a primary food source.

Antelope are herbivores with one notable exception: several duiker species have been observed killing and eating insects, small animals, and birds. Otherwise, antelope prefer to graze on grass or browse on bushes and tiny trees.

16. Hippos:

Do hippo eat grass

Do hippos consume grass? Yes, hippos are predominantly herbivorous animals that graze on grasses as part of their diet, despite their vast size and semi-aquatic environment. They are well-adapted for this feeding activity, biting grass from the ground with their strong jaws and sharp incisors.

Hippos are known to ingest a significant amount of grass at night, which helps them meet their nutritional needs. They also graze on aquatic flora found in the bodies of water they inhabit. This unique combination of land-based grasses and aquatic plants serves as the foundation of their diet, helping them to support their large bodies while remaining semi-aquatic.

According to Live Science, hippos have a “mostly herbivorous appetite,” consisting of around 80 pounds of grass per night, as well as fruits discovered during nighttime scavenges. So, you can also read more about how do hippos breathe underwater from this website.

17. Moose:

moose eat grass

Do moose eat grass? Moose eat grass as well as other sorts of vegetation. Moose are herbivorous mammals that eat a variety of plant materials such as grasses, leaves, twigs, and aquatic plants. Moose graze on a range of plants throughout the warmer months, including aquatic plants in lakes and ponds, as well as grasses in marshes and meadows. Their diet shifts with the seasons, and they eat a variety of plants based on availability and nutritional requirements. While grass is a part of their diet, it is not their main source of nourishment, and they rely on a variety of plant materials to complete their nutritional needs.

The majority of moose food comes from aquatic and marsh plants like horsetails and pondweed. Moose also consume grass, lichen, plants growing on the forest floor, peeled-off bark, and leaves torn from willows, sallow, and poplars with their bottom lip.

Final Words:

These animals demonstrate the range of herbivores that rely on grasses as an important part of their diets, as well as the intricate relationships between animals, their environments, and the plants they consume.

Grass isn’t extremely nutritious, therefore most herbivores require vast complex digestive systems to get the most out of it. Largely complicated digestive systems necessitate the use of large animals to transport them. However, if you wanted to subsist on the stuff, you’d need to consume about 8 pounds of greenery per day.


1. Why do animals eat grass?

Plants provide cellulose, fiber, and enzymes that are valuable to animals. As a result, some scientists believe that pets consume grass when their diet lacks fiber, minerals, or enzymes. They may resort to plant eating to promote digestion and boost intestinal health.

2. Which farm animal consumes the most grass?

Cows are avid grass eaters, making them perfect for huge expanses of land. They are easy to care for and will not try to flee. You might even use them to store milk. The problem with keeping cows is figuring out what to do with the manure, and they’re less eco-friendly than other animals because they emit methane.

3. What animals eat grass in Africa?

Herbivores can be surprisingly large animals. In Africa, there are many animals that consume grass like cow, buffalo, sheep, antelopes, waterbucks and deer are common.
