Recently, a black-and-white cow raised by a cow farmer in Datian Village, Liusong Township, Xianghe County had a postpartum paralysis. After healing by the author, the treatment experience is summarized as follows:

1. Clinical symptoms. The cow weighed more than 400 kilograms and was about 3.5 years old. The second child, born 3 days after birth, could not afford to stay in bed, and his mental status was poor. The livestock owner said that it was to bring the cows up with seven small public funds. Therefore, the cows were milked after they were born and squeezed for three consecutive days. To the onset, still crowded.

2. Treatment. First use a clean air pump to connect with a syringe needle. With your hand, swell slightly. The purpose is to make the mammary pressure, causing a decrease in lactation, preventing the loss of blood calcium and reducing the condition. Then by intravenous calcium, with 10% calcium gluconate 500 ml, 0.9% saline plus standard dose cardiac agents. Dosing was repeated 12 hours later and a standard dose of calcium, phosphorus, and magnesium was added. Two days later the cow recovered.

3. Experience. Cows should be given calcium lactate in an appropriate amount 1 month before delivery to prevent the disease; cows should be milked within 3 days after delivery, and should not be squeezed out. For the first time, 1.5 to 2 kilograms should be extruded better, and 1/1 of total milk should be squeezed on the first day. 3, 1/2 of the total milk squeezed the next day, 3/4 of the total milk squeezed on the third day, and then squeezed for a week. The number of milkings per day is changed from two times in the past to two times in the morning, evening and evening.

At present, as the price of milk is not high, some dairy farmers have changed from the past raw milk to small public funds and the development of beef cattle has been effective.
