Embodiment Construction

[0010] The method for selecting and breeding new cashmere goat multi-fetal strains comprises the following steps in turn:

[0011] ① From the cashmere goats, select the basic group of multiparity cashmere goats;

[0012] ②Locked breeding of the selected multiparity cashmere goat basic 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 excellent individuals whose first and second litters of ewes have more lambs and grow fast in the early s...

Abstract

The present invention discloses a cashmere goat polyembryonic new strain breeding method which includes the following steps: selecting and collecting polyembryonic cashmere goats as basic groups, and carrying out enclosed breeding of the cashmere goats, selecting excellent offsprings to build basic groups again, carrying out enclosed breeding of the selected the excellent offsprings, selecting excellent individuals from the offsprings through the enclosed breeding as core groups, carrying out enclosed breeding of the core groups, selecting excellent individuals from the offsprings through the enclosed breeding of the core groups, and obtaining the new strain of the polyembryonic cashmere goats. The present breeding method can effectively improve reproductive rates of cashmere goats, reduce production costs of female cashmere goats, improve breeding economic efficiency of cashmere goats, and can reduce the breeding number of female cashmere goats, save feeding grains, and speed up the industrialization process of cashmere goats.

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 cashmere goats is low, resulting in high production costs of goats, which affects the economic benefits of cashmere goat breeding to a certain extent. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the technical scheme that the present invention takes is: the breeding method of cashmere goat multi-fetal new strain, it is characterized in that: comprise the following steps: [0004] ① From the cashmere goats, select the basic group of multiparity cashmere goats; [0005] ②Locked breeding of the selected multiparity cashmere goat basic group; [0006] 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; [0007] ④ Carry out cl...
