Grass Tetany has been a problem already this year!

Grass tetany is low blood magnesium. Advanced symptoms look like milk fever. Early symptoms include excitement and twitching of muscles. Cows may also grind their teeth, convulse, and salivate a lot. Grass tetany is controlled with adequate dietary magnesium. The minimum dietary recommendation is 0.25% magnesium but some nutritionists recommend 0.40%. Other than at calving time, magnesium tetany is also seen when cows graze lush, grass pasture and dietary magnesium absorption is low.
