Raising the sheep's lambing rate is mainly to shorten the breeding cycle of the sheep. This production department uses two years of three-child technology. It is also a very effective measure to increase the efficiency of Shenlin sheep breeding. The first- and second-year three-child technology is to be mated in July of the first year, lambing in December, mating in March of the second year, lambing in August, breeding in December, and lambing in May of the third year, thus achieving two years The purpose of the three productions. Second, the use of artificial insemination technology to improve the breeding rate of Tan sheep. Artificial insemination technology has a higher requirement for Tan sheep breeding. The male ram that was collected semen required strong constitution, healthy and disease-free, strong sexual desire, and agile action, aged 2 to 5 years old. Before the start of breeding, the ram of each species must have collected at least 15 times or more. During the first few days, it can be used once a day. After that, it can be used every other day for 1 time. The number of rams for the breeding ram is 2%~5%. Select to stay. Breeding ewes should be raised before the breeding and breeding period, so that the ewes can be bred. The collected semen should pay attention to semen quality inspection, pay attention to the ejaculatory disk, semen color, semen odor, sperm motility and density, to meet the breeding requirements before breeding. Third, the use of "double lamb" (the main component of the pituitary gonadotropin, chorionic gonadotropin, release hormones, etc.), can stimulate multiple ovulation ewes, to produce double lamb, to improve the reproductive rate purposes. Fourth, the use of estrus technology over the same period. By injecting prostaglandol to the ewes to induce estrus at the same time and improve the breeding performance of the ewes. Fifth, promote the early weaning technique of lambs. Early feeding of lambs and early weaning are beneficial to the development of lambs, facilitate management of lambs, and facilitate the recovery of body condition of ewes, which promotes mating and breeding and improves reproductive performance. Lambs are generally required to wean milk on days 45 and 60.
