Cattle may suffer from a condition known as hardware disease caused by the ingestion of foreign bodies. The condition is often treated by encouraging the cow to swallow a cow magnet, a 7 cm rod magnet with an anti-corrosive covering. The magnet remains in the cow’s stomach and collects magnetic foreign bodies, rendering them harmless.
How do they insert a cow magnet into the cow?
The minerals are commonly known for the following benefits:
- Fe2O3 (97%) – Red blood cells growth
- Sr 84 O2 (1%) – Bone growth
- Ca (1%) – Bone growth
- Cu (1%) – Blood & Nervous System
How does a cow magnet get out of a cow?
Cow magnets. They're three-inch magnetized metal cylinders resembling lipstick cases. Farmers store them in the first of a cow's two stomachs. A plunger device inserts them into the cow's throat whereupon the cow dutifully swallows the magnet.
How many stomach magnets you should put in a cow?
To prevent cows from developing Hardware disease as a result of the ingestion of inedible objects, sometimes farmers will place a single “cow magnet” in the stomach of a cow. The magnet then attracts any metal objects and prevents them from travelling further through the body. However, this isn’t the only method of prevention.
How are magnets used with cows?

How are cow magnets inserted?
A rancher or dairy farmer feeds a magnet to each calf at branding; the magnet settles in the rumen or reticulum and remains there for the life of the animal. The magnet is administered after fasting the cow for 18–24 hours.
How are cows treated for hardware?
When hardware disease is suspected, placing a rumen magnet into the reticulum with a balling gun can sometimes cure the problem. Once the magnet settles in the reticulum, many times the hardware will attach, and be drawn away from the stomach wall and held in check by the magnet.
What type of magnet is used to prevent hardware disease to cows?
The best way to deal with hardware disease is prevention. Most grain elevators and feed dealers run their feed under magnets to catch any hardware. However, some objects may not be picked up. Cow magnets, which are administered like a pill, are also used to collect metal in the reticulum.
What happens when a cow gets hardware?
Hardware Disease occurs after an animal ingests a metallic object that then perforates the wall of the reticulum. This perforation results in an infection that can be mild or severe. In the cow or sheep, the reticulum is the first chamber of the forestomachs, lying under the bottom of the esophagus.
How does a cow magnet work?
In dairy cows, there is often a decrease in milk production. The cure is a magnet. A magnet is swallowed by the cow and attracts stray metal, keeping the metal in the cow's stomach. If the object leaves the stomach, it can pierce the reticulum and cause inflammation or death.
Can you butcher a cow with hardware disease?
If hardware disease is diagnosed by a veterinarian, and the animal has little or no value other than for market prices, slaughter may be recommended. If the animal is for breeding purposes or is a dairy cow, several treatments may be beneficial.
How strong is a cow magnet?
2200 - 2600 GaussStrength rated at 2200 - 2600 Gauss. As the name suggests, farmers feed these magnets to their cows to collect magnetic items in their digestive systems, preventing these harmful metal pieces from passing through.
Why do they feed magnets to cows?
Magnets are commonly used by farmers and ranchers to prevent Hardware disease, also called bovine traumatic reticuloperitonitis. Because cows do not discern objects with their mouth when eating and often swallow food whole, they are prone to eat dangerous metal objects like nails or wire.
Is hardware disease fatal?
Accordingly, hardware disease can be mild, severe or fatal. Hardware disease can be difficult to conclusively diagnose and clinical signs will vary based on where the hardware has penetrated.
What part of the digestive system is affected by hardware disease?
When a cow swallows hardware it gets caught in the second compartment of the stomach: the reticulum. The contractions of the reticulum are what make hardware disease deadly.
How do you get metal out of a cow?
If the cow was not given a magnet as a calf, the magnet can be administered once symptoms of hardware disease are observed – the magnet can extract the metal from the stomach walls. A course of antibiotics can also be administered to combat any bacterial infections that may have been caused by the metal.
What is a rumen magnet?
Rumen magnets 'capture' wires or fine metal material and thus prevent damage to the rumen and reticulum, and abscess formation and complications associated with wire migration. Wires and foreign bodies in the reticulum can cause discomfort and loss of production.
Why do cows have magnets?
Magnets are commonly used by farmers and ranchers to prevent Hardware disease , also called bovine traumatic reticuloperitonitis. Because cows do not discern objects with their mouth when eating and often swallow food whole, they are prone to eat dangerous metal objects like nails or wire. If one of these sharp objects were to pass through the reticulum it can puncture vital organs, causing pain and even death depending on where and how far the object travels. Because the stomach is so close to the heart in cattle, the most serious cases of Hardware disease are the result of an object piercing the heart and causing failure.
How to prevent cows from getting hardware disease?
To prevent cows from developing Hardware disease as a result of the ingestion of inedible objects, sometimes farmers will place a single “cow magnet” in the stomach of a cow. The magnet then attracts any metal objects and prevents them from travelling further through the body. However, this isn’t the only method of prevention.
What is the first thing a veterinarian will do to check for hardware disease?
When diagnosing Hardware disease, one of the first things that veterinarians will do is check for the presence of a cow magnet. Oftentimes, veterinarians will place a compass beside a cow’s stomach to detect the magnetic field.
Why is hardware disease so serious in cattle?
Because the stomach is so close to the heart in cattle, the most serious cases of Hardware disease are the result of an object piercing the heart and causing failure. Prevention of Hardware disease is the smartest ways to fight it.
Can magnets cause death?
Doing so can result in choking, harm to organs and even death, which is especially the case if two or more magnets are ingested at once. Because magnets will attract and pull towards each other, the presence of two or more can pinch organs and break bones.
About Hardware Disease
Hardware disease is a common term for bovine traumatic reticulopericarditis. It is usually caused by the ingestion of a sharp, metallic object. These pieces of metal settle in the reticulum and can irritate or penetrate the lining. It is most common in dairy cattle but is occasionally seen in beef cattle.
Causes of Hardware Disease
Cattle commonly swallow foreign objects, because they do not use their lips to discriminate between materials and they do not completely chew their feed before swallowing. Sharp metal objects (such as nails or iron wires) are a common cause of hardware diseases.
How to prevent the hardware disease?
A cow magnet is a kind of veterinary medical equipment used to treat or prevent hardware diseases of cattle. Traditionally, the cow magnets are strong Alnico magnets, in the shape of a smooth rod, about 1 cm by 8 cm (0.4 by 3.1 inches).

What is the best prevention for hardware disease in cattle?
The best prevention for hardware disease in cattle is a magnet. Many dairymen routinely put a magnet in each animal when cows are young. The best prevention in feedlot animals is to have all processed feed pass over magnets.
How to tell if cattle have hardware disease?
The most common signs of hardware disease in cattle are abdominal pain and discomfort. “The animal stands humped up with elbows out away from the body. Head and neck may be extended. The animal may be breathing hard, and grunt when it breathes. One way to check for hardware is to pinch the withers,” says Tibbitts.
What is hardware disease in cattle?
Hardware disease in cattle occurs when a sharp object penetrates the gut lining and damages some other organ or creates peritonitis (infection within the abdomen).
What is the second stomach of cattle?
The reticulum (second stomach, about the size of a volleyball, with honeycomb shaped compartments) is where the heavy material ends up. Once a nail or piece of wire (or sharp rock) goes through the stomach wall, it may puncture another organ or the heart cavity. The most common signs of hardware disease in cattle are abdominal pain and discomfort.
Why won't my animal touch my hardware?
But an animal with hardware won’t do this because it hurts too much to move away from your touch. “If a wire is just starting to migrate and the animal has peritonitis, fever will be 104 to 105°F. With a chronic case, it will be around 103°F.
Can rumen contractions be decreased?
Rumen contractions may be decreased. ”. At this stage, the problem might be mistaken for pneumonia. “Hardware can also be confused with an abomasal ulcer. These can show almost identical signs. With an abomasal ulcer, though, you usually see some blood in the stool, some dark, tarry stools.
How big is a cow magnet?
Magnets. Pictured above is a cow magnet, measuring about 8 centimeters long and 1 cm in diameter . The magnets are designed to sit in the cow’s rumen ( here’s a chart of sorts) — it’s small enough to get there, but too large to pass further. And it sits there collecting stray metal before it can cause the cow pain.
How many cow magnets did a 3 year old swallow?
Cow Magnets. In March of 2012, a three year old child in Oregon swallowed over three dozen magnet spheres. Each sphere measured only a few millimeters in diameter.
What is the strongest type of magnet?
But these magnets, known as neodymium magnets and marketed under the brand Buckyballs, were incredibly strong — per Wikipedia, neodymium magnets are the strongest type of permanent magnet made. As TIME reported, the magnets punctured the young girl’s stomach and intestines, requiring her to undergo surgery.
What happens if a cow eats metal?
When a cow accidentally ingests something metal, those metal pieces can get stuck in a part of their stomachs called the reticulum — and, over time, puncture holes in the lining.
Can cows eat humans?
But what’s bad for children may be OK for adults — and may be necessary for cows. Yes, cows. While humans are careful about what they eat, cows, well, aren ’t. Put some hay or grass or anything else to graze on in front of them, and they’ll mindlessly start eating.
Where do magnets go in cows?
A magnet about the size and shape of a finger is placed inside a bolus gun, essentially a long tube that ensures the magnet goes down the cow's throat. Then it settles in the reticulum, collecting any stray pieces of metal.
What is the magnet in dairy cows?
Dairy farmers routinely feed their cows a finger-sized magnet, which settles in the digestive tract to help keep the cows healthy. Wait what? This is no bizarre homeopathy, but rather a legitimate treatment for a stomach-churning ailment called "hardware disease."
What percentage of cows have hardware in their stomachs?
One report, from the 1990s, found that 55 to 75 percent of all slaughtered cows had hardware in their stomachs. Our landscapes are littered with stray pieces of metal, and sometimes, horrifyingly, they end up in our cows. Luckily, this low-tech magnet solution can work wonders.
Where does metal collect in the stomach?
All this metal eventually collects in the reticulum, the second of four stomach chambers.
Do cows chew before swallowing?
Advertisement. The problem arises because cows don't chew before swallowing. Of course, cows do famously spend pretty much all their time chewing cud, semi-digested food that is regurgitated from the stomach. When they're ripping up fresh hay or grass, though, they swallow large portions with barely any chewing.
What is a cow magnet?
Jump to navigation Jump to search. A cow magnet, which can be used to prevent hardware disease. Hardware disease is a common term for bovine traumatic reticulopericarditis. It is usually caused by the ingestion of a sharp, metallic object. These pieces of metal settle in the reticulum and can irritate or penetrate the lining.
Why do cattle swallow metal?
Cattle commonly swallow foreign objects, because they do not use their lips to discriminate between materials and they do not completely chew their feed before swallowing. Sharp metallic objects, such as nails or wire, are the common initiators of hardware disease. The object travels into the rumen and is then pushed into the reticulum along with the rest of the feed. In some cases, contractions of the reticulum can push the object through part of the reticulum wall into the peritoneal cavity, where it causes severe inflammation. In rare cases, the metal object penetrates the entire wall of the reticulum and can pierce the heart sac, causing pericarditis. Compression by the uterus in late pregnancy, straining during parturition and mounting during estrus can increase the likelihood of the object penetrating the abdominal wall or the heart sac.
How to tell if a cow has hardware disease?
Symptoms of hardware disease vary depending on where the object penetrates. The cow exhibits an arched back, a reluctance to move and a slow, careful gait. The cow may groan when lying down, getting up, defecating and urinating. The heart rate is normal or slightly elevated, and the respiration is shallow and rapid.
Can metal pierce the heart sac?
In rare cases, the metal object penetrates the entire wall of the reticulum and can pierce the heart sac, causing pericarditis. Compression by the uterus in late pregnancy, straining during parturition and mounting during estrus can increase the likelihood of the object penetrating the abdominal wall or the heart sac.
Is heart rate normal in dairy cows?
The heart rate is normal or slightly elevated, and the respiration is shallow and rapid. In dairy cows, there is often a decrease in milk production. Laboratory tests are not always necessary, but increases in fibrinogen and total plasma protein often result from hardware disease and may be diagnosed with a blood sample.
Can a second magnet cause pinching?
Depending on the type of magnet used, inserting a second magnet could cause internal pinching which could lead to serious complications. A broad-spectrum antibiotic should also be given to control infection. The cow should be confined and movement limited in the hopes that the reticulum can repair the hole.
What is a magnet used for in dairy?
Using magnets in the reticulum has become a popular preventive routine for hardware disease, especially in the dairy breeds. The magnet is administered much like a large bolus or pill, with a stomach tube or balling gun.
What is hardware disease in cattle?
Hardware Disease of Cattle. Hardware disease is produced by a sharp object that pierces the stomach wall and gains access to the heart. A sharp object, such as a nail or piece of wire, may perforate into the heart sac. The object lies originally in a chamber of the stomach known as the reticulum.
How long does it take for a cow to bloat?
The cow may also be bloated. These symptoms may subside or disappear within one to seven days, but may reoccur shortly afterwards. If the cow is slaughtered and the reticulum and heart carefully examined, it may be possible to find a nail or wire protruding through the wall of the reticulum into the heart.
What is the prognosis of hardware disease?
Prognosis is the prediction of the final outcome of the disease. The prognosis in hardware disease varies with the amount of infection present, how long the condition has been present, and the individual animal . The attending veterinarian considers several factors before making a final prognosis.
Why is my cow flabby?
The brisket may be quite flabby due to a large amount of fluid in it . The cow may also be bloated.
Does baling twine damage the digestive system?
Hardware may be present and yet produce no damage to the digestive system. Baling twine has replaced baling wire to a great extent, decreasing the noted frequency of hardware disease. During pregnancy, the rumen and reticulum are displaced forward.
Can hardware be digested?
However, the hardware may have been completely digested over a period of months and thus not be present. Sometimes abscesses or adhesions may be present between the reticulum and diaphragm, indicating a perforation had been present. Normally, the reticulum and diaphragm are not bound to one another.
