Improve the nutritional status of rams. The physical condition of rams has a great influence on the conception rate and lambing rate of ewes. Therefore, in the mating season, it is necessary to strengthen the feeding of rams and feed them with complete feeds. The feed should be rich in protein, vitamins and minerals. It is necessary to ensure sufficient exercise for rams in the barn, and use veterinary B-ultrasound to check the rams frequently to keep them in a medium to high fat condition. In this way, rams have high sexual desire, high ejaculation volume, high sperm density and strong vitality. When using this kind of ram for mating, the eggs are easy to fertilize and the twin rate is also high. It is very important to use veterinary B-ultrasound to check the physique of rams frequently.

Choose the right time for supplementary feeding. In order to improve the multi-birth and conception rate of ewes, it is also necessary to pay attention to strengthening the supplementary feeding of breeding ewes. Pay attention to the following time periods for supplementary feeding of ewes.

The production practice of short-term optimal feeding of sheep before mating has proved that nutrition has a great influence on the fertility of sheep. 1.0-1.5 months before mating, the ewes are suddenly fattened, and veterinary B-ultrasound examinations are performed. Some ewes with poor fat are fed for a short period of time, and the feeding amount of high-quality forage and other concentrated feeds is increased. This can not only maintain the normal estrus of the ewes, but also increase the number of ovulations and the twin rate of the ewes. In this process, veterinary B-ultrasound should be used for continuous monitoring.

Focus on supplementary feeding in the late pregnancy. The two months before delivery is the fastest stage of fetal growth and development. The fetus has a large demand for nutrition. In this stage, in addition to meeting its own needs, the ewes must also meet the rapid growth and development of the fetus and reserve enough nutrition for postpartum lactation. The burden is very heavy. Therefore, more than 90% of ewes' miscarriages occur during the production process. Therefore, veterinary B-ultrasound should be used for continuous monitoring at this stage. During production, it is necessary to strengthen the supplementary feeding of ewes. In addition to ensuring the supply of high-quality forage, concentrated feed should also be supplemented. Each ewe should be fed more than 250g of mixed concentrated feed every day. The supplementary feeding amount for ewes pregnant with twins should be appropriately increased. Veterinary B-ultrasound should be used for continuous monitoring. This can effectively reduce the abortion rate of ewes and increase the lambing rate.
