We are coming upon the time of year to be aware of the potential of grass tetney if your cattle will be grazing lush green forages in the coming months. Grass tetney is caused by a build-up of potassium nitrates blocking absorption of magnesium in the cow’s system.
Cattle suffering from grass tetney will be lethargic, have poor balance and be nervous. Cattle will eventually go down and will be unable to stand. Cattle at this point will need immediate attention or they will die as a result of this nutritional disorder.
The easiest way to prevent this is to supplement with a high magnesium product at least 28 days prior to grazing lush green forages. Formax Grazing Minerals are excellent supplements that will provide supplemental magnesium to your cattle.
Formax Grazing Minerals come in one of three formulas depending on the type of supplement desired. The Grazing Bronze is a more economically priced, high magnesium supplement while Grazing Silver and Grazing Gold are well-fortified, high magnesium minerals. All three minerals will provide the supplemental magnesium to prevent grass tetney. These products are very palatable and will encourage consumption and adequate intake on a daily basis.
Your local Quality Co-op will carry the Formax line or other high magnesium supplements to meet your needs.
