Grass Staggers is the common name for low magnesium in cows. This is most common in spring, when lush green grass is low in magnesium, and breeding cows are close to calving or producing milk. Grass staggers is also sometimes seen with fresh autumn growth or during periods of low feed intake. 


Common signs of grass staggers:

  • Restless, excitable, or aggressive cowslush green grass
  • Lack of co-ordination
  • Seizures
  • Sudden death.

Untreated grass staggers will rapidly result in seizures and death. There are solutions available to treat affected cows in an emergency, but prevention is a much better option. Trough treatment, pasture dusting or rumen boluses are some of the options available to ensure adequate levels of magnesium and prevent grass staggers.
