If you are like me and are tired of this cold-long winter, you are also looking forward to green grass and getting the cow-calf pairs out of the mud.
Most of us have heard about grass tetany but what does it mean and why should we supplement our cows with Hi Mag mineral?
Grass tetany is a magnesium deficiency that can occur in ruminants, like beef cattle, after grazing pastures in early spring that have rapidly growing grass. Grass tetany is most often associated with conditions of low magnesium and high potassium in growing pastures. Soil temperature, moisture, and fertilization can affect mineral levels. A cow’s requirement for magnesium increases after calving. Older animals are more at risk than young animals because they are not able to mobilize magnesium from bones like a young animal when magnesium in blood levels drop. Symptoms are loss of muscle control, irritability and unfortunately, this can result in rapid death.
Grass tetany is preventable by offering a Hi Mag mineral 2-3 weeks before grass exposure and fed for a month after first grass growth. Recent research suggests that heifers born to mothers that received adequate mineral supplementation are more productive throughout their lives than those born to inadequately supplemented cows. Fetal programming experts say that the benefits of mineral supplementation are way beyond the animal that directly ingests the mineral supplement.
At Central Valley Ag we offer a few options for Hi Mag mineral. Weatherized Hi Mag mineral bags are very popular, or if you prefer the convenience of a tub, we have them as well. Hi Mag minerals come in combination with Availa 4 for rebreeding and have the Altosid (fly control) option.
