Grass Tetany Prevention Starts Here: Burns Feed Store

It certainly feels like spring is on the way, and with its arrival comes the risk of Grass Tetany. Cows are currently facing a critical challenge in avoiding this condition during the mild winter weather we’re experiencing.

As this years winter begins to loosen its grip, we are currently noticing signs of early spring. Mild temperatures, cool soils, and fast-growing cool-season grasses may look promising, but these conditions can increase the risk of grass tetany, a serious and potentially fatal metabolic disorder in cattle.

Understanding Grass Tetany Risk

Grass tetany is most commonly caused by a magnesium deficiency, often occurring when cattle graze lush, rapidly growing cool-season forages. These forages can be low in magnesium and high in potassium, which interferes with magnesium absorption. Lactating cows are especially vulnerable during this transition period.

With the mild winter weather we’re currently experiencing, cattle may be exposed to these risk factors earlier than normal—making early mineral supplementation more important than ever.

Why Timing Matters

Preventing grass tetany isn’t something that can wait until symptoms appear. Producers are encouraged to begin offering a high-magnesium mineral 2–3 weeks before cattle start grazing rapidly growing spring pasture. This allows magnesium levels to build in the animal’s system before risk increases.

Supplementation should continue for at least 60 days after spring green-up, when grass tetany risk is typically highest.
