White Muscle Disease: Preventing Selenium and Vitamin E Deficiency in Cattle

Nutritional muscular dystrophy from selenium and vitamin E deficiency causes significant neonatal calf suffering that is entirely preventable through appropriate supplementation.

Key Facts

White muscle disease (nutritional muscular dystrophy) occurs in calves born to deficient cows
Both selenium and vitamin E deficiency can cause disease individually or together
Selenium-deficient soils produce forages low in selenium requiring supplementation of cattle
Clinical signs include muscle stiffness, inability to stand, respiratory muscle involvement, and sudden death
Affected calves show obvious distress - they cannot rise, suckle, or function normally
Selenium injection to pregnant cows 4-6 weeks pre-calving prevents most cases
Vitamin E supplementation alongside selenium is recommended given their synergistic roles

Welfare Considerations

White muscle disease causes acute, severe suffering in neonatal calves - affected animals cannot stand, exhibit obvious pain from muscle necrosis, and in cardiac or respiratory forms die rapidly. The condition is entirely preventable through selenium and vitamin E supplementation of pregnant cows before calving. Operations in selenium-deficient areas that do not implement supplementation programs cause entirely preventable suffering in newborn calves. Blood or liver testing of cows confirms selenium status and guides supplementation need before the next calving season.

What You Can Do

Test soil or forage selenium levels if you are in a known selenium-deficient area
Test cow blood or liver selenium status in autumn to assess supplementation need before calving
Administer selenium injection (barium selenate slow-release or sodium selenite) to pregnant cows pre-calving
Include vitamin E in supplementation programs given their synergistic protective roles
Treat affected calves promptly with selenium and vitamin E injection and supportive care
Monitor newborn calves from deficient cows closely in the first days for muscle weakness signs
Review supplementation protocols with your vet following any white muscle disease cases
