How to prevent dairy cows
The production of dairy cows accounts for more than 50% of the dairy cow's disease, which is a serious hazard to the dairy industry and should be given sufficient attention. Cows produce hemiplegia, which is usually caused by calcium deficiency and phosphorus deficiency. Under normal circumstances, it is mainly calcium deficiency. To control the production of hemiplegia in dairy cows, prevention should be done first. Usually in the pre-pregnancy period, high-phosphorus and low-calcium supplements should be used. The ratio of phosphorus to calcium should be 2 to 3:1. During the middle and late stages of pregnancy, calcium supplementation should be performed. Second, early detection of early treatment. In order to improve the cure rate of hemiparalysis in dairy cows, early diagnosis and early treatment with calcium preparations are needed. The commonly used calcium preparations for the treatment of dairy cows for clinical production are calcium gluconate injection and calcium chloride injection. Calcium gluconate contains 9% calcium and calcium chloride contains 27.3% calcium. The amount of calcium commonly used in the treatment of dairy cows for the production of hemiplegia is preferably 2.2 grams per 100 kg of body weight, equivalent to 244.4 milliliters of calcium gluconate injection or 161.2 milliliters of 5% calcium chloride injection. Generally 500 kg body weight cattle treatment dose of 1022 ml of calcium gluconate, or 806 ml of 5% calcium chloride injection, must be injected intravenously. In order to prevent the cows from being unable to stand due to insufficient doses or to suffer from recurrent hemiplegia, large doses should be used for the first injection. 8 hours to 12 hours after injection, there is no improvement, and the injection can be repeated at the original dose, but it is generally no more than 3 times. If calcium is used, the effect is still not obvious. When the second injection is used, slowly inject 15% sodium dihydrogen phosphate injection 200ml to 300ml and 15% magnesium sulfate injection 150ml to 200ml to promote recovery. .
