Overexcited muscles twitching molars raising sheep in spring beware of hypomagnesemia

When the grass germinates in spring, the sheep gradually change from house feeding to grazing, and the amount of grass eaten by the sheep is also increased. for example, the sheep in the transition period of the sheep farm lack control over the grass intake, and the sheep are gluttonous for a while, because the magnesium content in the grass (especially Gramineae) is low, but the potassium content is high, and potassium and magnesium are competitively absorbed in the sheep, which can easily lead to hypomagnesemia in some sheep (especially lactating ewes).

Sheep

The sudden movement of sheep is uncoordinated, excessively excited, intramuscular tetany, molars, especially lactating ewes, the disease is even more serious, it can be suspected that sheep suffer from hypomagnesemia, if coupled with blood examination of diseased sheep, the content of magnesium and calcium in their blood decreases, it is more helpful to the diagnosis. If the diseased sheep with hypomagnesemia are not treated in time, it will cause the diseased sheep to fall to the ground quickly, spasm, foaming at the mouth, coma and death.

The key to prevent hypomagnesemia during the transition period from house feeding to grazing in spring lies in prevention. Sheep are transferred from house feeding to grazing in spring. Regular prevention should be done for sheep farms with a history of hypomagnesemia. 8 grams of magnesite powder per day or 7 grams of magnesia (equivalent to 4.22 grams of magnesium) per day can be added to the concentrate feed of supplementary sheep. Sheep can produce obvious protective effect from the beginning of supplementation of magnesium preparation.

When sheep farmers supplement magnesium preparations to their sheep, they should pay attention to: because there is no obvious and effective mechanism to maintain magnesium balance in sheep and lack the ability to mobilize a large amount of magnesium storage, it is necessary to maintain the fine balance of serum magnesium in sheep to a great extent. it depends on the daily intake of magnesium preparation, such as once the sheep stop feeding magnesium preparation, when the intake of magnesium preparation is significantly reduced, or the utilization rate of magnesium intake is reduced. Its protective effect will be interrupted immediately, and it is very likely to cause hypomagnesemia in sheep farms. Therefore, for sheep farms with a history of hypomagnesemia, supplementation of magnesium preparation for sheep should begin during the transition period from house feeding to grazing. As always, supplementation of feed magnesium preparation in the concentrate feed of supplementary feeding sheep can achieve the effect of preventing hypomagnesemia in sheep.

At the same time, sheep farmers should pay attention to improving the content of magnesium in the vegetation of sheep grazing grounds. They can spray magnesite powder at a rate of 14 per hectare on the grassland of sheep pastures, or add magnesia to the fertilizer used in their grasslands. can achieve the role of preventing hypomagnesemia in sheep.

For the diseased sheep with hypomagnesemia, timely treatment measures should be taken: 20% magnesium sulfate solution 40-60 ml can be injected into the diseased sheep subcutaneously at one time, which can rapidly increase the blood magnesium concentration of the diseased sheep. The mixture of 25% calcium borate gluconate and 5% magnesium phosphate (1:1) 80 ml can also be used for intravenous injection of 25% calcium borate and 5% magnesium phosphate (1:1), and the therapeutic effect is good.
