The purpose of shortening the lambing interval is to interrupt the breeding cycle, ensure that the sheep can estrus, mate, and lamb every year, and then ensure that the ewes produce more lambs every year. The commonly used trial method is to place a vasectomized test ram in the flock 45 days after the ewe gives birth, preferably with the placement of a sponge plug containing progesterone. In this process, the sheep B-ultrasound should be used to check the follicles. Pregnant mare serum gonadotropin or a sustained-release agent containing follicle-stimulating hormone can be injected 58 days after delivery, and the previously placed sponge plug can be removed 60 days after delivery. At this time, the purpose of inducing estrus can basically be achieved, and the lambing interval can be effectively shortened to about 210 days. During the treatment of the same estrus process, the effect of follicle treatment should be monitored by sheep B-ultrasound. Using this method, clinical confirmation not only has a good effect on inducing estrus, but also can effectively increase the lambing rate. The induction of ewes is mainly to improve the reproductive environment of ewes with artificial measures to achieve the purpose of promoting high births per litter. It is very important to monitor them continuously with sheep B-ultrasound. At present, twin lambs and twin lambs are commonly used to induce ewes to produce more, and the effect of multiplication is better. Twin lambs (produced in Australia) used on the market can be injected subcutaneously in the neck of ewes 4-7 weeks before mating, and then reinforced with one injection 2-3 days before mating. The dosage is 2ml each time. The induction effect of production is better according to B-ultrasound observation of sheep. Twin lambs water can be injected subcutaneously 2-5 weeks before mating of ewes, with a dosage of 1ml/time; twin lambs oil can be injected 2 weeks before mating, with a dosage of 2ml/time.

Increasing energy levels before mating, sheep B-ultrasound can be observed to increase the number of ovulations and twin lamb rate of ewes, which is particularly obvious for ewes raised at low levels. Protein deficiency not only affects the estrus, conception or pregnancy of sheep, but also causes sheep to lose appetite, resulting in insufficient energy intake and weight loss, thus affecting the health and reproduction of sheep. Therefore, it is very important to observe the body condition of Sheep with B-ultrasound before mating.
