Ewes will lose weight due to lack of nutrition, coupled with the low temperature in winter, the length of light, ewes do not have enough light, it is very easy to lead to lack of vitamins and calcium and phosphorus imbalance leading to osteoporosis and softening, will lead to paralysis. In addition, ewes begin to lactation after delivery, colostrum will contain a lot of calcium, if the calcium is not maintained in time, it will lead to more and more blood calcium content of ewes, leading to the occurrence of this disease.

For ewes that are well developed but have been paralyzed in the past, the ratio of calcium and phosphorus in feed should be kept in balance, and the supply of calcium and high-protein feed should be reduced at half a month before delivery, so that it has a certain amount of exercise. Increase the duration of light and feed warm saline after delivery.
