back and legs fast peddling. These tetanic spasms give the name “grass tetany.” A cow that has been down very long will dig a hole with her feet and head.
Cattlemen who sea these symptoms in their cows should contact a veterinarian. Be sure to give the veterinarian a good history and condition of the cow, because time and type of treatment are very important.
Veterinarians should give immediate attention to affected cows and confirm the diagnosis by blood analysis, checking blood samples for normal mineral evaluation to differentiate between grass tetany and nitrate toxicity, milk fever or other conditions affecting the muscle and nervous systems.
Affected cows are normally treated wtih intravenous mineral supplements. But the best cure is prevention.
Supplement cows in the high-risk group with a high magnesium (13-14 percent), free-choice mineral mixture at least 30 days before grazing. The supplement, whether homemade or bought, should be palatable so cows will consume two to four ounces per head per day.
Soil testing and proper liming and fertilizing practices also help prevent grass tetany, as well as mixing in legumes with small grains to reduce nitrogen needs. It helps, too, to limit grazing, especially during critical weather conditions, and supplement the diet with hay or concentrates.
