Grass tetany is a highly fatal disease associated with low levels of magnesium in the blood. Grass tetany can affect all classes of cattle, but older cows with calves at foot during winter and spring are most at risk.

What is the cause of grass tetany?
Grass tetany, or hypomagnesia, is caused by low blood levels of magnesium. It is most prevalent when cows and ewes that are in late gestation or heavy lactation graze lush spring growth, usually in April and May, but cases can be seen in the fall.
What happens to cattle with a magnesium deficiency?
Grass tetany occurs when circulating Magnesium (Mg) is low in the beef animal. Symptoms include staggering, convulsions, excitability, twitching, and can result in death. While it can affect growing cattle, it generally affects older lactating cows.
What is the cause of milk fever in cows?
Milk fever is caused by a temporary blood calcium deficiency (also known as hypocalcemia) which usually occurs around the time of calving and is one of the most common metabolic disorder in dairy cattle.
When does grass tetany occur?
Grass tetany occurs when there is not enough magnesium in the blood. Adequate magnesium levels are required for proper brain and nerve function. The magnesium status of cows depends mainly on the balance between the amount of magnesium absorbed from the rumen and that lost in the milk.
Why do cattle need magnesium?
Magnesium is an important mineral for grazing cattle because of the association with grass tetany. Grass tetany is usually seen in cattle in the early spring when there is lush grass growth and cool, wet weather and is caused by a deficiency of magnesium to the cattle.
What does low levels of magnesium cause?
Over time, low magnesium can weaken your bones, give you bad headaches, make you feel nervous, and even hurt your heart. It can also lead to low levels of other important minerals like calcium and potassium. High levels of magnesium are much less common than low levels.
What does magnesium do for animals?
Magnesium (Mg) supplementation remarkably improves the digestibility of feed. In cows and sows, it has improved the reproduction and shortened the service period. In broilers it increased weight gain, and it has increased egg production of laying hens.
When do cattle need magnesium?
Cattle should begin consuming this high “mag” mineral during the late winter months and into early spring when new plant growth is starting. In late spring once temperatures are consistently above 60ºF, a producer can quit feeding the high “mag” mixtures.
What happens to an animals if they are deficient in minerals?
A trace mineral deficiency in cattle can go undetected for some time, but one critical deficiency can cause sudden death in cattle. If you're grazing cool-season forages, magnesium deficiency can cause sudden death in cattle. Most producers are aware when they need a high level of magnesium in the diet.
What causes calcium deficiency in cattle?
Low magnesium level in a diet, reduced calcium absorption in the gut. Reduced intake (high mycotoxin levels in the diet) High estrogen level around calving inhibits calcium mobilization. High calcium intake during dry periods reduces the ability for Ca utilization from other sources.
What was milk sickness?
The Plant that Killed Abraham Lincoln's Mother
"Milk Sickness," by definition, is poisoning by milk from cows that have eaten the White Snakeroot plant. "Milk Sickness" usually develops when a person drinks milk from an affected cow. However, it can also occur if the meat of an affected cow is eaten.
What is hypocalcemia in animals?
The term hypocalcemia is used when the level of calcium in the blood is lower than normal (hypo = “below”, -emia = “blood”).
How do cows get magnesium?
There are a number of ways to supplement cows with Mg and it is a case of choosing the right one for your farm: Magnesium in the water. Mg can be added to the water as a soluble salt or some companies sell a soluble Mg solution. They can be added to drinking troughs manually or via a proportioner pump.
What's magnesium do?
Magnesium is an important mineral, playing a role in over 300 enzyme reactions in the human body. Its many functions include helping with muscle and nerve function, regulating blood pressure, and supporting the immune system.
What is cow tetany?
Grass tetany, also known as “grass staggers”, “wheat pasture poisoning” & “winter tetany”, is a fatal metabolic disease caused by a low levels of magnesium in the blood serum of ruminant livestock including beef cattle, dairy cattle and sheep.
