The grass smashing disease is a disease mainly caused by typical neurological symptoms such as excitement and paralysis caused by a significant decrease in the blood magnesium index. The onset of this disease is sudden, and it is mostly acute and acute, and the harm is greater. Dairy cows, beef cattle and cattle are all ill. If you do not take effective treatment measures in time, it is easy to cause losses.
First, the cause of the disease
In the early spring, the amount of magnesium in the grass is relatively low and the potassium content is relatively high. The cattle eat a large amount of low-magnesium and high-potassium grass and cause grass to smash. After grazing in early spring, the incidence is most concentrated within 2-4 weeks, especially in the grasses or cereals that grow rapidly after the rain, magnesium, calcium, sodium ions and sugar are very low, while potassium and phosphorus ions are more, and the cattle eat this. After planting grass, it is easy to cause grass to smash.
Second, prevention measures
Paying equal attention to prevention and treatment is the principle of prevention and treatment of this disease. The specific prevention measures are:
1. Moderate grazing. It is not advisable to overgraze in the early spring, to avoid overfeeding the grass, and not to let the cows eat dew grass. It is best to graze for half a day for half a day, and not to allow the cow to continuously eat grass for more than 2 hours each time grazing, it is best to let The cow eats 6-7 percent.
2, the right amount of magnesium. In the early spring, for over-grazing cattle or over-supply grass cattle, it is best to add 50-60 grams of magnesium chloride per day to the concentrate to supplement the deficiency of magnesium.
3. Treatment methods. Treatment should be based on the specific body condition and size of the affected cow, with 20% magnesium sulfate solution 200-400 ml per day for three days or every other day intravenously or subcutaneously, for the first time with intravenous injection of 20% calcium gluconate solution 200 ml.
