Can Goats Survive on Grass Alone?

Goats are known for their great adaptability. They are low-maintenance animals and are not known to be susceptible to many diseases.

It can be raised with minimal means due to its great ability to search for a variety of plants and herbs. While goats are natural grazing animals and can derive their sustenance from grass, they cannot rely on it primarily for their diet.

This is evident from the precise understanding of its nutritional needs that delves into the needs of goats, the nature of their bodies, and how they grow and thrive.

This shows how much goats need a variety of foods to provide them with the nutrients they need. At the same time, goats may survive if there is only grass. But this cannot be considered a survival as the goats are in very poor health. Therefore, we cannot say that goats can survive only on grass.

Let us explain this in more detail in the following lines, examining the factors and reasons why grass alone is not sufficient for goats.

Can Goats Live on Grass Only?

No, goats cannot survive on grass alone. Even though they can graze on grass well, they are not primary grazers like cows and sheep.

Goats are only browsers, which means they prefer to taste and eat a variety of plants such as shrubs, leaves, twigs, and even weeds. However, it is not a sufficient source of nutrients for them. Therefore, they must be placed on a varied and balanced diet to provide them with the essential nutrients they need to grow and thrive.

Reasons Why Goats Cannot Live on Grass Alone

Low Protein Content

The grass is an excellent and essential source of fiber, but on the other hand, it is low in protein. While goats need a lot of protein for growth, muscle development, and milk production.

Deficiency of Essential Minerals

Although grass contains minerals, it does not provide goats with all the minerals they need, such as calcium, phosphorus, and zinc, which are necessary for bone health, muscle function, and many other bodily processes.

Vitamin Deficiency

Although the grass contains some types of vitamins, it also suffers from a deficiency in vitamins A, D, E, and K, which are considered essential for various body functions in goats.

Fat Deficiency

Grass consists largely of fiber, while it lacks a source of fat. Some people may think that this is a good thing, but in reality, it is not. Fat is not always harmful as some people think; it is one of the very important elements that goats need to build hormones and complete many basic functions.

Let’s take a look at the basic nutritional needs of goats so that we understand in detail why they cannot rely on grass alone and the importance of their need for a balanced and varied diet.

Nutritional Needs of Goats

Goats are ruminants, which means they have a complex digestive system. Their four-chambered stomach allows them to digest difficult plant material well.

However, their digestive system is not as efficient as that of cows and sheep, meaning they cannot extract all the nutrients found in grass, so they need a more varied diet to meet their nutritional needs.

The basic nutrients that goats need include:


Goats need high protein in their diet at 12-16% of their diet for growth, muscle development, and milk production.


Goats need fiber at 25-30% of their diet. This means that herbs are indispensable in their diet to provide them with the essential fiber they need to maintain a healthy digestive system.


Goats need a variety of minerals, including calcium, phosphorus, zinc, copper, iron, selenium, and manganese for bone health, muscle function, and other bodily processes.


Goats need vitamins A, D, E, and K, which are necessary for immune function and various other body functions.

Thus, we understand that grass alone cannot provide all the nutrients that goats need. It is a good source of fiber and should be in goat rations, but it is low in protein, minerals, and vitamins. Therefore, a balanced feed must be provided that provides all the nutritional elements for the goats.[1]

Consequences of a Grass-Only Diet for Goats

Sheep Eating Grass

Goats that eat only grass cannot thrive and often suffer from malnutrition, which can lead to a variety of health problems for the goats, such as:

Weight Loss

Grass does not provide adequate protein for goats. Therefore, goats that do not get enough protein cannot create strong muscle structures and will therefore be emaciated, their muscles will be weak, and they will lose weight.

Low Milk Production

Producing milk requires a lot of effort from the goat’s body and requires abundant nutrients for it to be produced properly. Goats that lack essential nutrients such as protein, minerals, and vitamins will produce less milk.

Health Problems

Goats that feed only on grass will lack many important nutrients that support immune functions and help strengthen their body structure. So you will be more susceptible to health problems such as pneumonia, diarrhea, and foot rot.

Therefore, it is necessary to provide goats with a balanced diet to ensure that goats receive healthy food that provides them with all their needs.

How to Provide a Balanced Diet for Goats?

To ensure that your goats get the nutrients they need, you will need to provide them with a balanced diet that includes a variety of feed sources. This may include:


Grass should be part of a goat’s diet to provide fiber, but it should not be the only source of food.


The diet of goats should contain hay because it is a good source of fiber and protein.

Legume Straw

Legume hay is a rich source of protein, so it is very beneficial for goats. Alfalfa or clover are good sources of hay for legumes


Grains contain many beneficial nutrients for goats. Therefore, the grains can be used as a nutritional supplement for protein and energy after grinding them.


Goats love to browse and it serves as entertainment for them and at the same time provides them with nutrients, so let the goats browse the bushes, leaves, and branches as it provides them with various nutrients.

Commercial Goat Feed

The concentrated and commercial feed can be a good supplement to a goat’s diet, but it is important to choose a feed designed specifically for goats and provide them in reasonable proportions.

Vegetables and Fruits

Vegetables and fruits provide a variety of nutrients, such as vitamins and minerals. So it is also beneficial for goats. You can provide kitchen and table scraps of vegetables and fruits to the goats, or buy them specifically for them during the fruit and vegetable seasons, depending on their types, as their price is inexpensive.

In addition to providing goats with a balanced diet, care must also be taken to provide goats with constant access to clean fresh water and include salt in small proportions in their diet.

It is necessary to monitor their health and vaccinate goats regularly to prevent parasites. By providing a nutritious diet and proper care for your goats, you will benefit first and foremost. Their productivity will increase, their illness will decrease, and they will be able to live a long and healthy life.


Why Do Sheep Need Grass to Survive?

Goats depend on grass to obtain fiber because it is an essential and rich source of fiber. Which is necessary and important to promote healthy digestion and prevent digestive problems such as bloating.

Can Sheep Survive Without Grass?

We cannot say yes, even if they can survive, but not in a healthy way, the lack of grass may lead to nutritional imbalance. Therefore, supplementary feeding becomes necessary, otherwise the goats will suffer from health problems.

Are Sheep Harder on Grass Than Cattle?

No, as goats are selective grazers, they are just browsers who taste different types of grass without eating them all like cattle. Therefore, it affects grass less severely than livestock. But in any case, proper management of pastures is crucial to preventing damage.

How Much Grass Does Sheep Eat in a Day?

Goats generally consume 2-4% of their body weight in dry matter. For example, a 100-pound goat will typically eat about 3-4 pounds of dry matter per day.

The amount of grass a goat eats daily depends on several factors, including its age, size, health, breed, and activity level.

Can Sheep Get Fat on Grass?

Goats often cannot be fat or gain weight on grass alone. Rather, it needs a varied diet of protein, fat, fiber, and other nutrients to thrive and gain weight.

Do Sheep Destroy the Grassroots?

Goats often cannot influence grassroots, as they are browsers and eat only superficial parts of the grass. But in any case, rotational grazing and proper management are a good solution to alleviate the problems of overgrazing.
