Grass tetany, also known as hypomagnesemia, wheat pasture poisoning, or grass staggers, is a metabolic disorder that primarily affects grazing ruminants, especially during seasonal pasture transitions. It is associated with insufficient magnesium intake or impaired absorption, leading to disruptions in neuromuscular function, reduced feed intake, and in advanced cases, muscle spasms, collapse, or even death if left untreated.

Causes and Risk Factors

Grass tetany most commonly occurs in early spring or during periods of rapid pasture growth. During these times, forage is typically high in nitrogen (N) and potassium (K) but low in magnesium (Mg). Elevated nitrogen and potassium levels interfere with magnesium absorption in the rumen, resulting in systemic magnesium deficiency.

When this mineral imbalance persists, animals become more susceptible to metabolic stress, particularly under high production demands or environmental stress conditions, leading to the onset of clinical symptoms.

Nutritional Support Strategies

Proper feeding management plays a critical role in reducing the risk of grass tetany and supporting recovery when symptoms occur. In addition to balanced rations, targeted feed additives can help regulate mineral balance and support metabolic stability.

Omega Hepatic Forte

A comprehensive nutritional support product formulated to enhance metabolic and immune functions. With its high magnesium content and complementary nutrients, it helps address magnesium deficiencies and contributes to reducing the risk of grass tetany.

Omega Rumen Balance

Developed to support rumen stability and fermentation efficiency. It helps maintain a balanced rumen pH and optimize nutrient utilization. Particularly beneficial during dietary transition periods, it aids in managing mineral imbalances that may arise.
