Full clinical detail
Overview
Hypomagnesemic tetany, also known as Grass Tetany or Grass Staggers, is a metabolic disorder primarily affecting cattle, sheep, and goats. It is characterized by low magnesium levels in the blood, leading to muscle spasms and neurological disturbances.
Causes
The primary cause of hypomagnesemic tetany is a deficiency of magnesium in the diet, often due to grazing on lush, fast-growing pastures. Other contributing factors include high potassium and nitrogen levels in the soil, which interfere with magnesium absorption.
Symptoms & Signs
Early Symptoms
- Restlessness
- Nervousness
Advanced Symptoms
- Muscle twitching
- Uncoordinated movements
Emergency Signs
- Convulsions
- Collapse
Diagnosis
Diagnosis is typically made based on clinical symptoms and confirmed through blood tests showing low magnesium levels. Urine tests may also help assess magnesium status.
Treatment Options
Home Care
- Ensure access to magnesium-rich supplements
- Provide a balanced diet
Veterinary Care
- Intravenous magnesium sulfate administration
- Oral magnesium supplements
Surgical
- No surgical options are available
Home Care
Providing adequate magnesium supplements and ensuring a balanced diet can significantly aid in managing and preventing the condition.
Prevention
- Offer magnesium supplements during high-risk periods
- Monitor pasture quality and soil mineral levels
Prognosis & Recovery
With prompt treatment, the prognosis is generally good. Recovery time varies but can be swift with appropriate magnesium repletion.
When to See a Vet
- Sudden behavioral changes
- Signs of muscle spasms or convulsions
