One is to choose to keep the lambs. Lambs born from lambs with a lot of lambs are also able to grow lambs when they grow up. The lambs produced by the ewes that have produced more lambs should be selected as breeding sheep. In the breeding process of sheep breeding, the ewes with low lambing rate are eliminated in time, and the sheep's overall production is increased. The second is the hybrid improvement method. Using a method of crossbreeding in a targeted manner can increase the sheep's lambing rate. For example, if a sheep is selected to improve the local sheep, the double lamb rate of the offspring may increase by about 35%, and the weight of the year-old will increase by more than 65%. The third is the drug lambing method. Twenty days before mating, each ewes neck was injected subcutaneously with 2 ml of dilavin, and 2 ml was injected 30 days before mating, and the lambing rate could be increased by 15% or more. Maternal muscles can also be injected with 20 to 50 micrograms of ovulation-promoting ovulation hormone 2 and the estrus rate is 86% after 3-5 days of treatment. The fourth is to shorten the lambing cycle method. Efforts should be made to reduce the ewes' empty time and strive to produce 2 or 3 births a year. Mating 60 days to determine if the ewes are pregnant; in the morning fasting sheep, the sheep's neck sandwiched between the legs, with both hands and forks from both sides of the uterus in front of the lower abdomen breast, gently hold up, with the left hand From the right belly of the goat to the left repeatedly pushing and kneading, such as the feel of two hard blocks, that is, there is a fetus; both hands feel a lump, for the twin lamb; if there is no hard block, the sheep are not pregnant. Light stimulation can also promote sheep estrus. The ewes and rams can be concentratively circled and given 15 to 20 hours of light each day. After 50 to 60 days, they are converted to natural light. Ewes can be estrus within two months. The fertility rate is higher after mating.
