Prevention: According to the feeding standards for ewes during pregnancy and lactation, prepare corresponding full value diets. In addition to meeting the energy and protein nutritional levels, the preparation process should also meet the requirements for trace elements, especially vitamin E and selenium. After using B-ultrasound to examine the reproductive system of sheep, add corresponding feed.

In daily feeding, it is necessary to carefully observe the feeding behavior, growth and development of pregnant and lactating ewes, and flexibly increase or decrease the amount of concentrated feed according to their fat condition. Some people have summarized the following experience: firstly, for ewes with good fat condition checked by B-ultrasound before mating, the supply of feed nutrients during pregnancy should be low in the beginning and high in the end; For sheep with poor fat condition and weak constitution detected by ultrasound before mating, they should be raised first, then lowered, and then raised again. The second is to reduce feed intake three days before delivery and completely stop feeding on the day of delivery, only providing a moderate amount of bran soup with a small amount of salt added; Gradually increase the amount of sperm feed 1-5 days after delivery, and restore normal sperm feed supply after 1 week; Reduce feeding three days before weaning and stop feeding on the day of weaning. Thirdly, during daily feeding, it is strictly prohibited to suddenly change the concentrated feed, feed moldy and spoiled feed, or supply ice water or unclean water (especially during the morning fasting time of pregnant ewes).

Good daily feeding management: Firstly, the hygiene of the enclosure, sports field, and surrounding environment should be maintained every day. Feces, residual grass, debris, etc. should be promptly removed, and strict disinfection, fly killing, and rat killing work should be carried out regularly. The second is to ensure that the sheep house (especially the meat sheep house) is warm in winter and cool in summer.

Under the harsh climate conditions of the plateau, giving birth to lambs in winter should be highly valued. On the basis of ensuring a certain temperature in the house, it is also necessary to prevent the invasion of thief winds. The third is to strictly control the feeding density, so that the mother and offspring have sufficient space for movement; Timely use sheep ultrasound examination to eliminate old, weak, sick, disabled and other sheep without feeding value, especially ewes with habitual vaginal prolapse, uterine inflammation and other diseases. The fourth is to control the reserve ewes to never participate when they have not reached physical maturity and a certain weight.
