Embodiment 1

[0016] A method for breeding a new multi-fetal line of meat goats, comprising the following steps in sequence:

[0017] ① From the meat goats, select the basic group of meat goats with multiple births;

[0018] ② Use the selected multi-fetal meat to carry out closed-breeding with the goat basic group;

[0019] 3. From the offspring of closed breeding in step 2., select ewes whose first and second litters have more lambs, and excellent individuals who grow and develop quickly in the early stage of lambs, and then establish a basic group;

[0020] ④ Carry out closed-breeding of the basic group established in step ③, and select excellent individuals from the closed-breeding offspring of ewes who have more lambs in the first and second litters and grow fast in the early stage of lambs to establish a core group ;

[0021] ⑤ Carry out closed-breeding of the core group obtained through step ④, and select excellent individuals whose first and second litters of ewes have more lambs a...

Embodiment 2

[0023] What is different from Example 1 is that: in steps ③, ④, and ⑤, when selecting ewes with more lambs in the first and second litters and with fast growth and development in the early stage of lambs, conventional gene analysis can also be used first. Methods The multiple-fetal genes were determined, and the conventional gene molecular marker method was used to select the ewes who had more lambs in the first and second litters and had fast growth and development in the early stage of ewes. All the other are with embodiment 1.

Embodiment 3

[0025] What is different from Example 1 is that: in steps ③, ④, and ⑤, when selecting ewes with more lambs in the first and second litters and with fast growth and development in the early stage of lambs, conventional gene analysis can also be used first. Methods To determine the multiple birth gene, and make a multiple birth gene chip, and then use the conventional gene chip technology to select the ewes who have a large number of lambs in the first and second litters and have fast growth and development in the early stage of ewes. individual. All the other are with embodiment 1.

Abstract

The invention discloses a method for breeding a new multi-fetal goat strain, which comprises the steps of selecting a basic group of multi-fetal goat goats and closed-breeding, selecting excellent offspring individuals to establish a basic group, and then carrying out closed-breeding, and breeding the offspring from the closed-closed breeding Select excellent individuals to establish core groups, core groups for closed breeding, and select excellent individuals from their closed breeding offspring to obtain new multi-fetal strains of meat goats and other steps. The invention effectively improves the reproductive rate of meat goats, reduces the production cost of ewes, improves the breeding economic benefits of meat goats, and can reduce the number of ewes to be raised, and can save feed grains, promote the industrial production of meat goats, and accelerate the production of meat goats. Industrialization process of meat goats. The new breed of goats with multiple births has been established, and the average lambing rate per litter of ewes has reached 350%, and the meat production performance fully meets the requirements of meat breeds.

Description

Technical field: [0001] The present invention relates to a method for animal breeding. Background technique: [0002] For a long time, the reproductive rate of high-quality meat goats is low, and the production cost of goats is high, which affects the economic benefits of meat goat breeding to a certain extent. Invention content: [0003] The object of the present invention is to provide a method for breeding a new multiple-fetal goat strain with strong fecundity and good quality. [0004] Technical solution of the present invention is: [0005] A method for selecting and breeding new breeds of meat goats with multiple fetuses is characterized in that it comprises the following steps: [0006] ① From the meat goats, select the basic group of meat goats with multiple births; [0007] ② Use the selected multi-fetal meat to carry out closed-breeding with the goat basic group; [0008] 3. From the offspring of closed breeding in step 2., select ewes whose first and second ...
