Embodiment Construction

[0010] The breeding method of a new breed of wool sheep with multiple fetuses includes the following steps in sequence:

[0011] ① From the wool sheep, select the basic group of multiple fetus sheep;

[0012] ②The selected multipartite sheep basic herd will be closed for breeding;

[0013] ③From step ②, select the excellent individuals of the first and second litters of the ewes who have more lambs in the first and second litters from step ② and establish a basic group;

[0014] ④The basic group established by step ③ is subjected to closed breeding, and from the closed breeding offspring, the first and second litters of the ewes are selected from the first and second litters, and the excellent individuals with fast growth and development in the early stage of the lamb are then established. group;

[0015] ⑤The nucleus group obtained in step ④ is subjected to atresia breeding, and from the atresia breeding offspring, the first and second litters of the ewes are selected with more lambs ...

Abstract

The present invention discloses a method for selectively breeding a new strain of multiparous wool sheep. The method comprises the following steps: selecting foundation stock of multiparous wool sheep and carrying out closed reproduction, selecting superior descendants to establish new foundation stock and carrying out closed reproduction again, selecting excellent descendants of the foundation stock after closed reproduction to establish nucleus stock and carrying out closed reproduction for the nucleus stock, selecting excellent descendants of the nucleus stock after closed reproduction to obtain the new strain of multiparous wool sheep, and the like. The method provided by the invention can effectively improve the reproductive rate of wool sheep, reduce the production cost of ewes, improve the economic efficiency of sheep wool breeding, reduce the breeding quantity of ewes, save feed grains, promote the factory production of wool sheep, and accelerate the industrialization process of meat sheep.

Description

Technical field [0001] The invention relates to an animal breeding method. Background technique [0002] For a long time, the reproduction rate of high-quality wool sheep has been low, resulting in high production costs for wool sheep, which has affected the economic benefits of sheep breeding to a certain extent. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the technical solution adopted by the present invention is: the breeding method of a new breed of wool sheep with multiple fetuses, which is characterized in that it includes the following steps: [0004] ① From the wool sheep, select the basic group of multiple fetus sheep; [0005] ②The selected multipartite sheep base group will be closed for breeding; [0006] ③From step ②, select the excellent individuals of the first and second litters of the ewes who have more lambs in the first and second litters from step ② and establish a basic group; [0007] ④The basic group established by st...
