White muscle disease (WMD) is a degenerative muscle disease found in all large animals, including sheep, goats, and cattle. It is caused by a deficiency of selenium and/or vitamin E, which play important roles in protecting the body from oxidative damage. The disease can affect both skeletal and cardiac muscles, leading to a range of symptoms such as stiffness, pain, and difficulty breathing. While there are treatments and preventive measures available, such as selenium and vitamin E supplementation, the effectiveness varies depending on the form of WMD, and it is often a challenge to manage. So, is white muscle disease curable?

White Muscle Disease is caused by a deficiency of selenium and/or vitamin E
White Muscle Disease (WMD) is a degenerative muscle disease found in all large animals, including sheep, goats, and cattle. It is caused by a deficiency of selenium and/or vitamin E. Selenium is an essential mineral that plays a crucial role in various bodily functions, while vitamin E is a fat-soluble vitamin with antioxidant properties.
Role of Selenium and Vitamin E in the Body
Selenium and vitamin E are both powerful antioxidants that work together to protect the body from oxidative damage. Selenium is a key component of selenoproteins, which are involved in regulating mitochondrial function, energy transport, oxidative damage control, and calcium homeostasis for proper muscle contraction. On the other hand, vitamin E prevents oxidative damage to cell components. Together, they protect the skeletal, cardiac, and respiratory muscles from degeneration.
Causes of Selenium and Vitamin E Deficiency
Selenium deficiency is often associated with soils that are low in selenium content, leading to inadequate uptake by plants grown on these soils. Certain areas, such as Michigan in the U.S., are known to have selenium-deficient soils. Vitamin E deficiency, on the other hand, is independent of soil type and is more closely linked to the quality of forage. Fresh legumes and pasture are good sources of vitamin E, while stored feeds and certain types of crops tend to be poor sources.
Symptoms and Treatment
WMD typically affects newborns or fast-growing animals, causing stiffness, weakness, and difficulty standing or walking. It can affect both the skeletal and cardiac muscles. While the skeletal form of WMD can be successfully treated with selenium and/or vitamin E supplements, the cardiac form often results in permanent damage or death. Preventative measures include supplementing the diets of pregnant animals and providing selenium-fortified salt or mineral mixtures to susceptible animals.

Selenium supplements can be used to treat the disease
White muscle disease (WMD) is a degenerative muscle disease found in all large animals, including sheep, goats, and cattle. It is caused by a deficiency of selenium and/or vitamin E. Selenium is a trace mineral that plays a crucial role in protecting the body from oxidative damage. It is a component of selenoproteins, which help regulate mitochondrial function, energy transport, oxidative damage control, and calcium homeostasis for proper muscle contraction and function.
The deficiency in selenium is often associated with selenium-deficient soils and the inadequate uptake of selenium by forages grown on these soils. Certain areas, like Michigan in the USA, are known to have low selenium levels in their soil. This results in the forages grown in these areas also being deficient in selenium, leading to a lack of selenium in the diet of animals that graze on these pastures.
Supplementing the diet of affected animals with selenium is a key treatment approach for WMD. Selenium supplements can be administered in various forms, such as sodium selenite, selenium-fortified salt or mineral mixtures, intraruminal selenium pellets, or even through soil application of selenium in fertiliser. The recommended supplemental level is 0.3 ppm of selenium, calculated based on the total dry matter intake.
It is important to note that the addition of selenium to animal feeds is regulated in some countries, including the USA, due to the minute quantities involved and the potential toxicity of excess intake. Therefore, caution must be exercised when using selenium supplements, and appropriate authorities should be consulted. Consulting with a veterinarian, nutritionist, or a specialist team, like the MSU Extension beef team, is crucial to devising a safe and effective treatment plan for WMD in affected herds.

Vitamin E supplements can also be used to treat the disease
White muscle disease (WMD) is a degenerative muscle disease found in all large animals, including sheep, goats, and cattle. It is caused by a deficiency of selenium and/or vitamin E. The disease can affect the skeletal and cardiac muscles, with symptoms including stiffness, difficulty standing, and respiratory distress.
Vitamin E plays an important role in protecting the body from oxidative damage. It acts as a natural antioxidant, preventing oxidative damage to parts of the cells in the body. Fresh legumes and pasture are good sources of vitamin E, while stored feeds and certain types of crops tend to be poor sources. Prolonged storage of feed can result in a significant loss of vitamin E activity over time.
Vitamin E supplements can be used to treat WMD, especially when the disease affects the skeletal muscles. The recommended treatment is 50 mg (68 IU) of vitamin E per 18 kg (40 lb) of body weight, which can be administered SC (subcutaneously) or IM (intramuscularly). This treatment has been shown to be effective, with animals responding within 24 hours. However, it is important to carefully follow the recommended dosages and administration guidelines, as excessive intake of vitamin E can be toxic.
In addition to treatment, vitamin E supplements can also play a role in preventing WMD. Supplementing the diet of susceptible animals with vitamin E can help reduce the risk of developing the disease. This is especially important for pregnant animals, as selenium and vitamin E deficiencies can be transferred to the fetus and increase the likelihood of WMD in newborns.
It is always advisable to consult with a veterinarian, nutritionist, or other expert when dealing with WMD or any other health condition in animals. They can provide specific recommendations and guidance based on the individual needs of the animals and help monitor their health and response to treatment.

The disease is most common in newborns or fast-growing animals
White muscle disease (WMD) is a degenerative muscle disease found in all large animals, including sheep, goats, and cattle. It is caused by a deficiency of selenium and/or vitamin E. Selenium and vitamin E play important roles in protecting the body from oxidative damage. A deficiency in either of these nutrients can lead to WMD, which is most common in newborns or fast-growing animals.
In newborns, WMD can cause weakness and an inability to rise or stand. It can also affect the heart, tongue, diaphragm, and other large muscles in the legs and back, leading to respiratory distress and even sudden heart failure. Older lambs and kids may exhibit stiffness, hunching, and a stilted gait. They may also have difficulty standing and nursing due to weakness.
WMD is commonly seen in offspring of animals that graze on pasture or consume crops grown in selenium-deficient soil. Certain areas, such as Michigan in the U.S., are known to have low selenium levels in the soil. Selenium-deficient soils can lead to inadequate uptake of selenium by forages, which in turn affects the animals that consume them. Additionally, vitamin E deficiency is independent of soil type and is more closely related to forage quality.
To prevent WMD, supplementation with selenium and vitamin E is crucial. This can be achieved through various methods, such as adding selenium to animal feed, using selenium-fortified salt or mineral mixtures, or applying selenium to the soil. However, caution is necessary as excessive selenium intake can be toxic. It is important to consult with veterinary professionals and follow label directions when administering treatments.
The treatment approach may vary depending on the form of WMD. The skeletal muscle form of the disease can often be successfully treated with supplemental selenium and/or vitamin E. However, the cardiac muscle form of WMD is usually challenging to treat, and the damage to the heart muscle is often permanent.

The disease can affect the skeletal and cardiac muscles
White Muscle Disease (WMD) is a degenerative muscle disease found in all large animals, including sheep, goats, and cattle. It is caused by a deficiency of selenium and/or vitamin E. Selenium and vitamin E play important roles in protecting the body from oxidative damage. While vitamin E deficiency is independent of soil type, selenium deficiency is associated with soils that have low selenium levels, and the inadequate uptake of selenium by forages grown on these soils. Certain areas of the U.S., including Michigan, are considered low in selenium levels.
The disease can affect both the skeletal and cardiac muscles. When the skeletal muscles are affected, symptoms can range from mild stiffness to obvious pain upon walking, to an inability to stand. Affected lambs/kids may remain bright and have normal appetites, but eventually, they become too weak to nurse. When the problem occurs in newborns, they are born weak and unable to rise. In calves, the muscles in the upper portion of the front legs and the hind legs are degraded, causing the animal to have a stiff gait and it may have difficulty standing. The skeletal muscle lesions associated with the delayed form of WMD are usually bilaterally symmetrical and can affect one or more muscle groups. The muscle will have white striations and feel dry and chalky due to abnormal calcium deposits.
When WMD affects the heart, calves are usually found dead or in respiratory distress and die soon after due to sudden heart failure. When the disease affects the heart, the animal shows signs similar to pneumonia, including difficult breathing, a frothy nasal discharge (which may be blood-stained), and fever. Heart rate and respiratory rate are elevated and often irregular. The cardiac muscle damage caused by WMD is often permanent.
WMD can be prevented by supplementing the diet of susceptible animals with selenium and vitamin E. Since it occurs mostly in lambs and kids whose mothers were fed a selenium-deficient diet, supplementation of pregnant animals helps reduce disease in newborns. This is because selenium is transferred from the mother to the fetus across the placenta and is also present in the colostrum.
