If you’re reading this resource, there are likely some special goat residents in your life who you’d like to provide the best possible care for! The compassionate lifelong care of goats at animal sanctuaries starts with the food they’re provided. While goats are all individuals who have their own preferences and needs, there are some general principles to consider in their physiology and nutritional needs!

Young Goat Kids Have Their Own Dietary Needs!
For information about the dietary needs of kids, check out our resource here.

Like sheep and cows, goats are ruminants. Rather than directly receiving nutrients from the food they eat, goats must first ferment their food in their complex digestive system consisting of a four-chambered stomach and then absorb the nutrients out of the resultant fermented mixture. Due to the way they absorb nutrients, they need to be gradually introduced to new and novel food if changing their diet is necessary; abruptly changing their diet can lead to bloat and other digestive issues.

Daily Food For Goats

While many people lump sheep and goats together as having the same dietary needs, there are actually quite a few key differences between what they want and need when it comes to food. First, while sheep are grazers, goats are browsers. They can (and do) eat grass, but they also forage for other foods such as brush and woody vegetation (these plants are referred to as “browse”). A healthy goat’s diet should consist primarily of goat-safe vegetation, either fresh (in the form of quality pasture and browse) or dried (in the form of hay).

The amount of food a goat needs is often estimated on a dry matter basis (“dry matter” refers to what would remain if all of the moisture was removed from the food). The amount of dry matter a goat needs to consume in order to meet their nutritional needs depends on many factors including the temperature, the type and quality of the food, and the individual (their weight, life stage, general health, and activity level all factor in). Because of this, there is a wide range of estimates different sources provide regarding dry matter intake, ranging from below 2% to 6% of their body weight. According to Susan Schoenian, Sheep & Goat Specialist for University of Maryland Extension, in order to meet their nutritional requirements, goats generally need to consume 2-4% of their body weight in dry matter. By offering foraging opportunities and/ or hay free-choice, individuals can consume as much food as they need (though some individuals may require additional supplementation on top of this and others may need their intake restricted, in which case your veterinarian can make specific recommendations regarding their dietary needs). In order to maintain healthy rumen function, goats typically need at least 7% dietary crude protein and at least 50% dietary fiber.

Pasture And Browse Vegetation

While we often talk about pasture in terms of outdoor space and food sources for goats, as browsers, they thrive in outdoor spaces that provide both the opportunity to graze on pasture and also the opportunity to browse. Keep this in mind when designing outdoor spaces for your goat residents. If available, browse will typically make up over 60% of a goat’s diet. According to Sheep And Goat Medicine, Second Edition, most goats prefer browse over grass and grass over legumes. Your local cooperative extension office should be able to recommend browse plants and a pasture seed mix (containing grasses and forbs) for your residents that will grow well in your area, but if you care for male goat residents, be sure to ask about plants that are suitable for neutered males, as some forages may increase the risk of urinary calculi

Before giving goats access to outdoor spaces, ensure that they have been thoroughly checked for toxic plants! Your pastures should be divided up and their use rotated throughout the season to give the foliage time to regenerate and to lower the chances of residents ingesting parasites, especially barber pole worm, in the pasture. When considering rotation for regeneration, don’t forget about browse plants. Goats can easily kill plants by eating all of the foliage, so you’ll need to rotate them accordingly (you generally need to leave at least 20% of the foliage if you want to have any hope of the plant surviving, though some plants may require a higher percentage of foliage remaining). It can be helpful to plant some shrubs, bushes, and trees along the fenceline on the outside of a goat herd’s outdoor space so that some foliage is within the residents’ reach, but a portion of it remains protected. Another idea is to plant trees or large shrubs inside their living space and protecting them with solid fencing to prevent goats from stripping tree bark or otherwise destroying the plant. This is especially helpful if there is a limited amount of browse in their space or if frequent rotation is not possible. 

Immune Response To Barber Pole Worm In Goats Vs. Sheep
Overall, goats tend to develop a weaker immune response to barber pole worm than sheep. As natural browsers, a large percentage of their diet consists of vegetation that is higher off the ground than how high the parasites typically migrate. Sheep, on the other hand, primarily graze, eating grass closer to the ground which is more likely to expose them to higher numbers of parasites. This key difference in foraging behavior may explain why goats have not developed the same type of immune response as sheep. However, this weaker immune response leaves them more vulnerable in settings where they have to graze on pasture for the bulk of their food. You may want to explore incorporating plants that are high in condensed tannins such as sericea lespedeza, sainfoin, and big trefoil as research suggests they can be beneficial in managing worms. We recommend having a discussion with your veterinarian or a nutritionist about which plants to use and in what proportion to ensure all of their nutritional needs are being met.

Grass Hay

Although a diet consisting solely of grass is not a natural diet for goats, when fresh vegetation is not available, residents will need to be fed grass hay, such as timothy or orchard grass. The specific variety will depend a lot on your location and what is available. Hay can come in multiple cuttings, with 1st and 2nd being the most frequently used. The cutting simply indicates when the hay was harvested (cut) for the season- first cutting was harvested first, second cutting is harvested second, and so on. In some areas, first cutting may be all that is available to you- it all depends on your region, the growing season, and your supplier. Depending on the type of hay you use, there may be physical and nutritional differences between the different cuttings. For example, when comparing first and second cutting timothy hay, first cutting is typically coarser than second cutting, which is often richer, softer, and also more expensive (though in some cases, first and second cutting may look very similar).

It’s best to provide hay in a hay feeder in order to keep it clean and dry and to reduce waste. Be wary of hay feeders designed for horses, as certain styles can pose the risk of entrapment for goats, particularly wall-mounted styles with tapered vertical bars that have wider gaps towards the top that narrow at the bottom. A goat may fit their entire head in the gap at its widest point but then become trapped when they bring their head closer to the ground. We’ve heard devastating stories of goats dying as a result of getting stuck in these feeders- either from strangulation or breaking their neck trying to free themselves- so we recommend using a safer type of hay feeder for both sheep and goats.

Watch That String!

If you are feeding goats hay that was baled with string, you must keep track of all the string as you cut it and be certain to remove all pieces from the goat’s food. Goats cannot be allowed to eat string under any circumstances! Learn more about this challenge at your sanctuary here.

Limit Or Avoid These

Alfalfa pastures should not be used generally for goat feeding as its high calcium and protein content can cause health issues like obesity and urinary calculi. Urinary blockages are especially dangerous in neutered male goats, and therefore it’s best to avoid feeding alfalfa to them.  Alfalfa should only be fed to babies or females who are pregnant, recovering from an illness, or struggling to keep weight on.

Grain (and formulated goat food from farm supply stores) should be highly limited (if not typically non-existent) on a goat’s menu. It can easily cause obesity and painful and dangerous urinary calculi in goats. It can also cause laminitis. Grain should only be offered to goats who need the extra nutrition due to weight loss or illness on the recommendation of a veterinarian, but there are alternatives that can be used to supplement a goat’s diet without the risk that comes with grain and concentrates; healthier options for supplemental feeding includes soaked timothy hay pellets or a mix of soaked timothy and beet pulp. If you do offer grain to goats, talk to your veterinarian about ammonium chloride supplementation to prevent struvite calculi.

Bloat Dangers

Goats should not graze on abundant clover or alfalfa that is wet or moist from rain or dewdrops, nor should they have free access to grain stores, nor should they be allowed unlimited access to a brand new pasture with unfamiliar foliage on it. Situations like these can lead to bloat or grain overload, which are serious health emergencies. To prevent bloat on a new pasture, gradually introduce the goats to it by letting them browse for only a few minutes each day for a few weeks, slowly allowing longer browsing time if they seem healthy.

Water For Goats

Like every sanctuary resident, goats require a clean, freely-accessible water supply. The amount of water your residents will consume in a day varies based on their size, the temperature, and the water content of their food, but in general a non-lactating goat will drink 1-2 gallons of water each day. Water consumption will increase as temperatures rise, and individuals eating hay will drink more water than those eating lush grass and other vegetation due to the much lower moisture content of hay. Individuals who are pregnant or lactating will require more water than those who are not- on average between 2-4 gallons per day. Automatic watering systems with thermostats for automated heating are a good option to minimize spilling and keep the goats well-hydrated in freezing conditions.

Minerals And Supplements For Goats

Goats should always have ready access to goat-formulated minerals, either in the form of loose minerals or from mineral blocks. These help supply goats with essential nutrients like calcium, chlorine, sodium, phosphorous, magnesium, sulfur, potassium, Vitamins A, D, and E, and trace minerals like copper, cobalt, iodine, iron, manganese, molybdenum, selenium, and zinc.

Generally, a goat should be fed a 2 to 1 calcium-to-phosphorous ratio in order to prevent urinary calculi.

Copper? No Sheep Sharing!

If you are caring for both goats and sheep, it’s critical that you do not feed sheep any minerals formulated for goats. Sheep are very sensitive to copper and can easily suffer from copper toxicity. Goats can safely eat minerals formulated for sheep, but if you choose this route for both species, you may need to provide goats with copper supplementation, such as through copper wire boluses administered under the instruction of a veterinarian. Copper deficiency can lead to anemia, a dull coat, bone disease, diarrhea, and increased susceptibility to parasites.

Even with an appropriate diet and mineral supplementation, deficiencies are still possible. If you are concerned about specific vitamin or mineral deficiencies, you should consult with your veterinarian. In some cases, simple blood tests can be used to screen for deficiencies, but with certain nutrients, diagnosing deficiency is more complex.  If you are worried about the quality of their hay, you can get it tested for nutritional analysis.

Goats can be given access to black oil sunflower seeds on occasion to naturally boost their vitamin E and other trace minerals, which can benefit their overall health and improve their coat.

If the goats in your care have been very susceptible to bloat in the past, your veterinarian may recommend offering a little baking soda in addition to their mineral mix, but be aware that too much baking soda can cause urinary calculi, so you must weigh the risks for your residents.

If you change the available mineral mix for your goat residents, be sure to watch closely to make sure your residents are consuming the appropriate amount (as some are more or less palatable than others) and watch for any signs of potential nutritional imbalances.

Most healthy goats will get enough protein from quality forage or hay, but those who are growing or lactating have higher protein requirements and may need supplementation. Individuals who are ill, especially those dealing with internal parasites, might also require additional protein. If protein supplementation is necessary, talk to your veterinarian about the best options for your residents. There are mineral formulas that contains added protein, or they may recommend offering an oilseed meal or other protein source. It’s important to meet your residents’ protein requirements without greatly exceeding them, as too much protein can contribute to certain health issues such as pizzle end rot. Most goats who are not growing or lactating require around 7-8% protein.

Treats For Goats

You should not feed too many treats to goats, as they can become overweight or develop urinary calculi quite easily. However, an occasional treat can go a long way in keeping goats happy (or motivated to come to you if they’ve snuck out of their living space!) Once you’ve ensured that they’re cut down to goat bite-sized pieces, safe and healthy goat treats include vegetables and very limited fruit such as:

  • Banana
  • Carrot
  • Celery
  • Grapes
  • Lettuce
  • Pears
  • Pumpkin
  • Squash
  • Sunflower Seeds
  • Watermelon
  • Apples

Foods You Should Not Feed To Goats

There are a number of foods that contain potential toxins or substances goats cannot digest or tolerate. You can find our list of potentially toxic foods here.

Special Food Recommendations For Older Goats

While some older goat residents may continue to thrive on a standard goat diet consisting of fresh or dried forages, others may require certain modifications or supplementation. It is not uncommon for elderly goats to lose weight, which could be due to various issues such as dental disease, an underlying health condition (such as CAE), or eating less due to environmental factors or social dynamics. You should be very mindful of an older goat’s weight so that you can catch weight loss early. It’s important to identify the cause of the weight loss, take steps to address the issue, and make changes to their diet, living arrangement, and/ or environment, based on their needs. In some cases, you may need to separate the individual one or more times per day so you can offer them supplemental foods to ensure they are getting all the nutrients they need. To read more about diet recommendations for older goats, in addition to other care considerations, check out our resource here!
