Preventing Grass Tetany

Ranchers are determined to protect their cattle. Some killers are easy to spot, like a pack of hungry predators. Grass tetany is more of a silent killer, but it is equally as dangerous. It is important to know the facts to protect your investment.

Grass tetany, also known as grass staggers or wheat pasture poisoning, occurs when the magnesium level in the blood falls below the critical level.  Grass that is susceptible to producing grass tetany is often low in magnesium, calcium and sodium, but high in potassium.

Causes of Grass Tetany

Rio Grass TetanyGrass tetany is caused in early spring grazing when the grass is very lush (very wet) and very high in soluble protein.  Protein is made up of nitrogen and is converted to usable protein in the body.  With high solubility of the nitrogen/protein it can cause protein poisoning which can lead to quick death if not corrected. Too much and too rapid movement of protein/nitrogen going into the bloodstream causes death.

Early pasture grass contains more potassium than the body can utilize effectively.  The soil releases more potassium than magnesium into the plant during early season.  Therefore, higher levels of magnesium are needed to offset this imbalance.

This is the reason why we have to feed more magnesium during early grazing.  Cattle should receive magnesium ahead of time for 30 days prior to going to pasture.  This is why we have an elevated level of Mag in all of our products. Occasionally, one might have to strategically add additional magnesium to a salt mix for free choice feeding.
