Problems solved by technology

[0003] At present, sheep breeding enterprises and farmers adopt the method of natural estrus and natural mating during the breeding season, which makes the breeding efficiency of sheep low, and only produces one lamb per year
Not only the reproductive efficiency of ewes is low, but also the reproductive efficiency of rams is also low. The ratio of male and female sheep in the group is 1:30-50, so a large number of rams need to be raised, and because breeding rams require high nutritional levels all year round, Greatly increased the cost of feeding

Abstract

The invention relates to the field of animal-husbandry breeding, and discloses a three-yield-in-two-year multi-lamb technology for mutton sheep in a farming-pasturing interlaced area. The technology includes a production cycle control method, an estrus ovulation regulating method, artificial insemination and nutrition regulation. The production cycle control method is the three-yield-in-two-year breeding technology; the estrus ovulation regulating method is the CDIR, FSH and PMSG method; nutrition regulation includes medicine nourishing and food nourishing. According to the three-yield-in-two-year multi-lamb technology, the super-ovulation and artificial-insemination technology is carried out with exogenous hormones, the breeding cycle of sheep is shortened to 8 months from 12 months, the feeding proportion of colonial rams and colonial ewes is decreased while the hybridization success rate is guaranteed, and the culture benefits of the sheep are remarkably increased.

Description

technical field [0001] The invention relates to the field of animal husbandry and reproduction, in particular to the technology of mutton sheep producing multiple lambs in two years and three times in the interlaced area of ​​agriculture and animal husbandry. Background technique [0002] Since the end of the 1990s, the production mode of my country's sheep industry has undergone a fundamental change, from the traditional use of both wool and wool to meat and meat, and the benefits of the mutton sheep industry depend on their breeding. efficiency. Since the sheep breeds in my country are all local breeds that breed seasonally, they only enter the breeding season in autumn (September-November) each year, and most of them only produce one lamb, so it is already necessary to use modern reproductive biology techniques to improve the reproductive efficiency of meat sheep. Become the technical key point of the industrialization development of the mutton sheep industry. [0003] At...
