Embodiment Construction

[0010] The method for breeding new breeds of multi-fetal sheep with both meat and wool, comprises the following steps in turn:

[0011] ① From the meat and wool dual-purpose sheep, select the basic group of multi-parity meat and wool dual-purpose sheep;

[0012] ②Locked breeding of the selected multi-parity meat and wool dual-purpose sheep base group;

[0013] ③ From the offspring of step ② closed-breeding, select ewes whose first and second litters have a large number of lambs and who grow fast in the early stage of lambs, and then establish a basic group;

[0014] ④ Carry out closed-breeding of the basic group established in step ③, and select excellent individuals from the closed-breeding offspring who have more lambs in the first and second litters of ewes and grow fast in the early stage of lambs, and then establish a core group. group;

[0015] 5. Carry out closed-breeding of the core group obtained through step ④, and select ewes from the closed-breeding progeny who h...

Abstract

The present invention discloses a method for selectively breeding a new multiparous strain of meat and wool dual-purpose sheep. The method comprises the following steps: selecting foundation stock of multiparous meat and wool dual-purpose sheep and carrying out closed reproduction, selecting superior descendants to establish new foundation stock and carrying out closed reproduction again, selecting superior descendants of the foundation stock after closed reproduction to establish nucleus stock and carrying out closed reproduction for the nucleus stock, selecting superior descendants of the nucleus stock after closed reproduction to obtain the new multiparous strain of meat and wool dual-purpose sheep, and the like. The method provided by the invention can effectively improve the reproductive rate of meat and wool dual-purpose sheep, reduce the production cost of ewes, improve the economic efficiency of meat and wool dual-purpose sheep breeding, reduce the breeding quantity of ewes, save feed grains, promote the factory production of meat and wool dual-purpose 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 reproductive rate of high-quality meat and wool sheep has been low, resulting in high production costs of meat and wool sheep, which has affected the economic benefits of sheep breeding to a certain extent. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the technical solution adopted by the present invention is: a breeding method for a multi-fetal new strain of sheep with both meat and wool, which is characterized in that it includes the following steps: [0004] ① From the meat and wool dual-purpose sheep, select the basic group of multi-parity meat and wool dual-purpose sheep; [0005] ②Locked breeding of the selected multi-parity meat and wool dual-purpose sheep base group; [0006] ③ From the offspring of step ② closed-breeding, select ewes whose first and second litters have a large number of lambs ...
