Cow postpartum paralysis is an acute hypocalcemia that occurs before and after the birth of a cow. Especially in recent years, with the rapid development of the dairy industry, especially the high incidence of high-yield dairy cows, it has brought great economic losses to farmers. The main features of the disease are depression, loss of appetite, muscle tremors in the extremities, unstable standing, paralysis, and lying in the ground. Loss of consciousness occurs in severe cases, and body temperature drops to about 35 degrees. 1. Cause: 1.1 Incorrect feeding and management. Because cows have a lot of energy after birth, they lose more water. Together with the increase of lactation, especially the highest content of calcium discharged from colostrum, so that the body calcium, phosphorus and other trace elements imbalance, the body to maintain calcium balance, we must strengthen the intestinal absorption of calcium and bone calcium mobilization, if the feed formula Irregular feeding tubes such as light can cause cows to paralyze due to calcium deficiency. 1.2 After the cows were born, the blood circulation in the breast and the control and regulation of the activity of the mammary glands did not reach the normal state. The breasts swelled badly and the internal pressure was also high. Especially for high-yielding dairy cows, some people had to milk more. The milk in the breasts is completely squeezed, so that the internal pressure of the breasts is significantly reduced, causing the phenomenon of microscopic blood vessel leakage to increase, blood calcium, blood glucose loss, further aggravate breast edema, resulting in postpartum cramps, severe cases and even death of dairy cows. 1.3 In the process of calving, due to the weakness of the cow, the cow causes various degrees of prolapse of the uterus. When the uterus is not satisfied, the disinfection is not strict, the pollution is serious, or when the fetal position is not correct, the fetus is pulled out. Causes endometrial or vaginal damage. Sometimes postpartum placental clothing does not subside, and failure to properly peel off the childbirth can lead to serious bacterial infections, which can lead to local inflammation, eventually leading to systemic infections. 2. Control measures: 2.1 Strengthen nursing, increase nutrition, and promote rehabilitation. After the yak has been produced, the cows are fed warm water and a small amount of salt and calcium carbonate are added to the water. At the same time feed a small amount of high quality, soft hay. 2.2 In order to prevent bacterial infections caused by midwifery, detachment of the placenta, and prolapse of the uterus, certain local hygiene and disinfection must be performed during the operation. A 0.1% potassium permanganate warm solution can be used to flush the prolapsed uterus. The instruments used during the operation should be strictly disinfected. According to many years of clinical experience, the systemic intramuscular injection of streptomycin and streptomycin prior to the onset of cow production is effective. Once systemic infections or even various causes of hemorrhoids can be taken intravenous infusion therapy, generally take 10% glucose 500-1000ml, 5% sugar saline 1000ml, soda 500ml? Compound brine 500-1000ml, 10% calcium gluconate 800- 1000ml, Vc injection 30-50ml, Anca coffee 10-20ml, on the body of inflammation can add penicillin 16000000, streptomycin 8000000, once intravenously, once every 3 days. It has a good therapeutic effect on the disease. 2.3 Chinese medicine treatment: Angelica 30 grams, 30 grams of fennel, 18 grams of two ugly, 18 grams of Atractylodes, 18 grams of Chuanzizi, 18 grams of fenugreek, myrrh 18 grams, 18 grams of Sakamoto, safflower 12 grams, wood Pass 12 grams, 12 grams of licorice, 200 grams of rice wine, fine medicine research, into the yellow wine and warm water, once fed, once every 3-5 days. 3, summary: 3.1 due to this disease is mainly caused by calcium deficiency, so feeding and management is the key, especially in the winter season, more to add some soft high-quality hay, to ensure the normal supply of calcium feed and vitamins, regular exercise, drying The sun keeps the bar house clean and dry. For diseased cows, you cannot squeeze colostrum into space and squeeze out 2/3 milk. 3.2 During midwifery, be sure to follow the operating procedures, pay attention to disinfection, do not use too much force, resulting in tissue damage. In the intravenous infusion treatment, symptomatic treatment can be. For cows with low body temperatures, 0.5% hydrocortisone 80-100 ml may be added to prevent shock. The amount of calcium should be selected according to the size of the cow, the severity of the disease, and the condition of the heart. Usually two calcium injections are ineffective, and other complications should be suspected. When calcium is injected, it should not be too fast. The good response to calcium therapy is hernia, muscle tremors in abdominal ribs, enhanced heart sounds, and moistened nose.
