Grass Tetany is a nutritional disorder, generally associated with inadequate levels of magnesium in the blood. It commonly occurs in lactating beef, dairy and sheep animals consuming lush temperate forages such as ryegrass and small cereals crops like wheat, barley and oats when magnesium levels are less that 0.2% and potassium levels greater than 2-3% and crude protein greater than 20%.
Magnesium can become limiting when pastures are rapidly growing, or when the weather is consistently cloudy and the uptake of magnesium from the soil is reduced. It can also occur after heavy nitrogen or potassium fertilisation of pasture, especially if calcium is low in the forage. The high level of these minerals can affect the uptake of magnesium through the rumen wall.
The initial signs of a magnesium deficiency include nervousness, decreased milk yield, and attentive ears, staggering, twitching skin. Older cows and high milk production cows are more susceptible because they may have decreased body stores of magnesium.
The best strategy is prevention; this means ensuring that your bail, TMR or supplement contain sufficient magnesium to minimise the risk of Grass Tetany in the coming ryegrass and/or cereal grazing season.
Don’t hesitate to consult Goldmix Stockfeeds for the most appropriate feed or supplement for your cattle or sheep. Alternatively ask your local Norco Rural Store
