Cows do eat mushrooms, and it is common for them to do so. However, it is not advisable to include mushrooms as part of their regular feed. Cows have multi-stage stomachs that allow for the complete digestion of grass and grain products. While cows are smart enough not to eat poisonous mushrooms, accidental ingestion can occur, and it doesn't take much to cause problems. There have been documented cases of mushroom poisoning in calves, and while the chances of poisoning are slim, it is something to be aware of, especially when conditions are right for mushrooms to grow.

What You'll Learn
Cows can eat mushrooms
While cows can eat mushrooms, it is probably not a good idea to include them as part of their regular feed. Ruminants generally have multi-stage stomachs that allow for the complete digestion of grass and grain products, and they have the digestive components to break these down. However, their digestive systems are sensitive to complete changes in diet due to the 'bugs' that live in their guts.
There have been documented cases of mushroom poisoning in beef calves, and while the chances of this occurring are slim, it should be considered if nothing else seems to be the cause of illness. If cows are allowed to graze in areas with many mushrooms, it may be a good idea to identify the mushrooms using an app like iNaturalist, where users can upload pictures of organisms, and other users can help identify them.
It is possible to intentionally feed cows mushrooms by creating a mushroom spore slurry and adding it to their feed or water source. However, adding unknown substances to a cow's diet can be dangerous, and spores can cause issues if inhaled in large concentrations in enclosed areas.

Not all mushrooms are safe for cows
Cows are known to eat mushrooms, and it is common for them to do so. However, not all mushrooms are safe for cows to consume. While cows are smarter than we give them credit for when it comes to eating, they are not infallible. They may eat mushrooms that are poisonous to them, especially if hungry with no other feed available.
It is important to note that cows typically do not consume mature psychedelic mushrooms, but rather the spores, which do not contain the hallucinogenic compound psilocybin. However, this does not mean that all mushroom spores are safe for cows. Some mushrooms are highly toxic to cows, and consuming the wrong type or amount of spores can be dangerous.
While cows generally avoid eating what is dangerous to them, there is a risk of them ingesting poisonous mushrooms, especially if they have access to a variety of feed options. Some sources suggest that cows will eat things that are poisonous to both themselves and humans, indicating that they do not always have an innate sense of what is safe to eat. Therefore, it is important to be cautious when allowing cows to graze in areas where mushrooms may be present.
Additionally, while cows have multi-stage stomachs that allow them to fully digest grass and grain products, their digestive systems may not be equipped to handle large amounts of mushrooms as part of their regular diet. As such, while cows may occasionally eat mushrooms without harm, it is not advisable to include them as a regular part of their feed.

Poisonous mushrooms can cause sudden death in cows
Cows do eat mushrooms, and while they are usually good at detecting poisonous mushrooms, they can still eat toxic mushrooms and die from mushroom poisoning. Poisonous mushrooms contain a variety of toxins that can cause different types of harm. The most common toxin that leads to severe poisoning is amatoxin, which blocks the replication of DNA, leading to cell death and, eventually, organ failure and death. Amatoxin poisoning can be treated if quick, professional care is provided.
The most common species of amanita containing poisonous mushrooms along the West Coast are Amanita phalloides (Death Cap) and Amanita ocreata (Destroying Angel). Death Cap is abundant in warm, wet years and can be found near oak, birch, and pine trees, as well as in open pastures. Destroying Angel occurs from Baja California along the Pacific Coast to Washington and is commonly found in the foothills and valley floors. Poisonings from amanitin have occurred not only in people but also in dogs and horses, and presumably cows. The poison is extremely potent, and one or two Death Caps could kill an adult cow.
Symptoms of mushroom poisoning can vary from slight gastrointestinal discomfort to death within about 10 days. Serious symptoms do not always occur immediately after eating, often not until the toxin attacks the kidney or liver, sometimes days or weeks later. The most common consequence of mushroom poisoning is simply gastrointestinal upset, which can cause vomiting and diarrhea. However, there are recognized mushroom toxins with deadly effects, such as α-amanitin, which shows no symptoms for 6-12 hours after ingestion.
If you suspect mushroom poisoning in your cattle, contact your veterinarian to discuss the case and get help identifying the cause. Collect any mushrooms you observed where the animal was grazing and submit them, along with the carcass or tissues, to a diagnostic lab. Taking close-up photos of the mushrooms may also aid in diagnosis. Toxicological tests are necessary to confirm poisoning, and rumen content, liver, kidney, and urine samples are the best tissues to submit.

How to identify poisonous mushrooms
While cows do eat mushrooms, it is not advisable to feed them mushrooms as part of their regular diet. Ruminants have multi-stage stomachs that allow for the complete digestion of grass and grain products.
Now, if you want to know how to identify poisonous mushrooms, here are some detailed instructions:
Firstly, it is important to note that learning how to identify poisonous mushrooms is crucial if you plan on foraging for edible mushrooms. Mushrooms with white gills are often poisonous, so be sure to check the underside of the mushroom cap for this colour. Amanita mushrooms, for example, usually have white or very pale gills and are poisonous. Another way to identify Amanita mushrooms is by their dry, umbrella caps. Other toxic mushrooms to look out for include Galerina, jack o'lantern, shaggy parasols, and false morels. False morels can be distinguished from true morels by their caps, which hang freely from the stem, unlike true morels whose caps are fully attached.
Secondly, the presence of a volva, especially a coloured one, at the base of a mushroom stem is typically an indicator of a poisonous variety. Dig around the base of the mushroom to check for this bulbous growth, as it is often underground. In addition, mushrooms with a ring around the stem are often poisonous.
Thirdly, the colour of the mushroom can be a helpful indicator. While not all red mushrooms are poisonous, many of them are. If you are unsure about the variety of mushroom, it is best to avoid those with red on the cap or stem.
Fourthly, the smell of a mushroom can also provide clues as to its toxicity. Poisonous mushrooms tend to have an acrid, chemical, or fishy odour, while edible mushrooms usually have a pleasant earthy aroma.
Lastly, it is important to consult a mushroom guidebook or online resource, and even consider joining a mycological group, to learn about the specific edible and poisonous mushrooms in your area. Remember, if you are ever uncertain about the identity of a mushroom, do not eat it.

Can cows trip on magic mushroom spores?
Cows typically eat grass or grains that are covered with spores of psychedelic mushrooms. These spores are tiny reproductive units of fungi that do not contain psilocybin, the active compound in psychedelic mushrooms that causes hallucinations in humans. Therefore, cows do not trip on magic mushroom spores.
Psychedelic mushrooms, often called "magic" mushrooms, have hallucinogenic properties due to the presence of psilocybin. While cows may consume these mushrooms or their spores, the mushrooms themselves are not a significant part of their regular diet.
The spores of psychedelic mushrooms are microscopic and can be found on grass or grains that cows eat. These spores do not contain psilocybin and therefore do not have the same hallucinogenic effects as the mature mushrooms. However, when cows ingest these spores, they can survive the digestive tract and be present in their manure.
The conditions provided by cattle farming, such as cow dung and pasture soil, are ideal for the growth of certain species of mushrooms, including Psilocybe cubensis. This species is often found near cattle and can be cultivated indoors or transferred to new habitats by cattle egrets, which walk alongside cattle and spread the spores through spore-laden vegetation and cow dung.
While it is possible to intentionally seed a cattle farm with mushroom spores, it is important to consider the potential risks. Introducing large concentrations of spores in enclosed areas can be dangerous, as certain types of spores can cause lung infections or other health issues. Additionally, the regular consumption of mushrooms or spores as part of a cow's diet may have unknown effects and should be approached with caution.

Frequently asked questions
Cows do eat mushrooms, but it is not recommended that mushrooms become a regular part of their diet. While cows are smart enough to avoid poisonous mushrooms, accidental ingestion can occur and it doesn't take much to cause problems.
There is no specific treatment or antidote for mushroom poisoning in cows. Supportive care can be provided to help the animal clear the toxin from its system.
You can use a phone app called iNaturalist where users, including scientists, help identify mushrooms. There is also a test kit available that identifies amatoxins in small amounts of mushroom tissue or urine from an animal suspected of consuming poisonous mushrooms.
The chances of mushroom poisoning in cattle are slim, but it is still a concern when conditions are right for mushrooms to grow. There have been two documented cases of mushroom poisoning in beef calves in California in 2008 and 2009.
Cows do not typically consume mature psychedelic mushrooms. Instead, they ingest the spores, which do not contain psilocybin and therefore do not have hallucinogenic properties.
