Understanding Strokes In Cattle: Causes And Prevention

Cattle owners have reported symptoms in their cows that suggest the animal has had a stroke. A stroke is a blood clot that obstructs normal blood flow to a part of the brain, causing brain cells to die. Symptoms of a stroke in cows include a drooping ear, a squinting eye, a drooping mouth, and excessive drooling. However, it is difficult to determine whether a cow has had a stroke, as it is a term used to describe a range of neurological conditions. Cattle can also experience heat stroke, which can be identified by the animal's open mouth, heavy breathing, lethargy, and increased salivation.

Cattle can experience heat stress, which can lead to heat stroke

Cattle are susceptible to heat stress, which can be fatal. In June 2022, thousands of cattle in southwestern Kansas died of heat stress, with temperatures soaring above 100°F. This was due to a combination of high temperatures, high humidity, and low wind speed.

Cattle can struggle to regulate their body temperature in hot weather, particularly when temperatures remain high overnight. They are also vulnerable to heat stress when they are digesting food, and if they have not shed their winter coats.

Heat stress can be mitigated by providing cattle with shade, water, and ventilation. Ranchers can also alter the feeding schedules of their cattle so that they are not digesting food during the hottest parts of the day.

There are several stages of heat stress in cattle, with the most severe resulting in open-mouth breathing, protruding tongues, and isolation from the herd. Cattle owners should be vigilant for these signs, as early intervention is critical to the survival of the animal.

Signs of heat stress include elevated breathing rate, drooling, and lethargy

Heat stress is a significant issue for cattle, and it can be challenging to identify and manage. High temperatures, particularly when they persist into the night, can cause cattle to experience heat stress, and it is crucial to recognise the signs to prevent long-term implications.

Signs of heat stress in cattle include elevated breathing rates, drooling, and lethargy. These symptoms indicate that the animal is struggling to regulate its body temperature and may be in distress. The combination of high day and nighttime temperatures can be deadly, as cattle are unable to cool down effectively.

Elevated breathing rates are a critical indicator of heat stress. As the stress intensifies, cattle may begin to drool slightly, progressing to excessive drooling or foaming at the mouth in more severe cases. The drooling is often accompanied by increased restlessness, with the animals spending more time standing.

Lethargy is another key sign of heat stress. Cattle may exhibit a lack of energy, with their heads held low. They may also show decreased muscle tone and, in extreme cases, become too weak to stand. These symptoms can progress rapidly, and it is essential to intervene early to prevent further deterioration.

To manage heat stress, it is recommended to minimise handling and transportation of cattle during hot weather. Providing ample water, shade, and ventilation is crucial. Additionally, ensuring access to pasture with trees or open buildings can help cattle regulate their body temperature.

A stroke occurs when a blood vessel becomes blocked or narrowed, disrupting blood flow to the brain

Yes, cattle can have strokes. A stroke occurs when a blood vessel becomes blocked or narrowed, disrupting blood flow to the brain. This can be caused by a blood clot, tumour cells, bacteria, or parasites. The blockage or narrowing of the blood vessel prevents blood and oxygen from reaching the brain, causing brain cells to die.

In cattle, signs of a stroke may include a drooping ear, a drooping mouth, squinting, lethargy, and increased salivation. These symptoms may indicate a more serious underlying condition, such as rabies or listeria. It is important to consult a veterinarian if you suspect your cattle are exhibiting signs of a stroke or any other health issues.

While strokes in pets seem to occur less frequently than in people, they often occur on a grander scale and require immediate veterinary attention. The exact cause of strokes in cattle can be difficult to pinpoint, as they do not have the same risk factors as humans, such as greasy foods, smoking, or alcohol consumption. However, underlying diseases, such as Cushing's disease or heart disease, may increase the risk of a stroke in animals.

Strokes in cattle can have varying impacts on their health and well-being. In some cases, cattle may recover with proper veterinary care and supportive care from their owners. In other cases, the impact of the stroke may be more severe, and the animal may need to be put down to end its suffering.

Cattle can exhibit neurological signs, such as loss of muscle control, abnormal behaviour, and seizures

A stroke occurs when a blood vessel becomes blocked or narrowed, preventing blood and oxygen from reaching the brain, which results in the death of brain cells. In cattle, strokes may be caused by blood clots, tumour cells, bacteria, or parasites. However, the exact cause of strokes in cattle can be difficult to pinpoint, as they do not have the same risk factors as humans. Underlying diseases, such as Cushing's disease or heart disease, may increase the risk of stroke in cattle.

Neurological signs exhibited by cattle can vary depending on the severity of the damage and the area of the brain affected. For example, a stroke in the cerebellum can result in lowered head carriage, a wide-based stance, and incoordination, particularly in the hind legs. Bacterial meningitis, another condition that can affect cattle, may cause early clinical signs such as a lack of sucking behaviour, depression, and weakness. As the disease progresses, the affected calf may become blind and exhibit seizures before death.

If you suspect that your cattle are exhibiting neurological signs or are experiencing a stroke, it is important to consult a veterinarian immediately. They will be able to evaluate the animal's brain function and recommend further diagnostic tests, such as MRI or CT scans, to determine the cause of the symptoms.

While strokes in cattle may not be common, it is important for farmers and veterinarians to be aware of the potential risk and signs to ensure prompt diagnosis and treatment.

If you suspect your cattle are suffering, consult a veterinarian immediately

• Drooping or lathargic appearance on one side of the body
• Drooping ear
• Squinting or abnormal eye movement
• Drooling
• Inability to eat or drink
• Loss of balance or coordination
• Seizures
• Blindness or impaired vision
• Change in personality or behaviour, such as aggression or isolation
• Difficulty walking or standing
• Elevated breathing rate
• Lethargy

It is important to note that these signs may also be indicative of other health issues, so a prompt veterinary evaluation is crucial for an accurate diagnosis and treatment plan. Do not attempt to diagnose or treat your cattle on your own.

Additionally, take preventive measures to maintain the health and well-being of your cattle. This includes providing adequate nutrition, ensuring access to clean water, maintaining proper hygiene, and implementing effective biosecurity measures to prevent the spread of infectious diseases. Regular veterinary check-ups can also help identify potential health risks and ensure the overall well-being of your cattle.
