Embodiment 1

[0041] A method for cultivating a new breed of sheep with both meat and milk, using small-tailed Han sheep as the female parent and East Frisian sheep as the male parent for progressive hybridization, through optimal combination and cross-cross fixation, to breed a new breed of sheep with both meat and milk, Specific steps are as follows:

[0042] Step 1. Identify and evaluate East Frisian sheep and Small-tailed Han sheep, and select excellent East Frisian sheep and Small-tailed Han sheep to form a breeding group;

[0043] The selection criteria for the male parent East Fried sheep are: tall, wide and long body, body height greater than 70cm, body width greater than 40cm, body length greater than 100cm, birth weight above 3.5kg, weaning weight above 30kg, adult weight 90~120kg ;

[0044] The selection criteria for the female parent Small-tailed Han sheep are: tall body, more than 70cm in height, strong limbs, with limbs longer than 40cm; body length greater than 110cm, in a b...

Abstract

The invention mainly relates to a dual-purpose sheep new strain cultivation method. The method includes the steps that grading crossing is conducted by taking a small tailed han sheep as a female parent and an eastfrierian sheep as a male parent, and a dual-purpose sheep new strain is cultivated through optimization combination and crossing fixation. According to the dual-purpose sheep new strain cultivation method, the cultivated dual-purpose sheep new strain is strong in reproductive performance and good in milk production performance, the lambing percentage is more than 210%, in terms of a table purpose, the figure of the new strain sheep is bettern than that of the small tailed han sheep, the meat performance is good, the feed price is high, the average weight of female lambs weaned in the third mouth can reach 30kg, a one-year-old female sheep is 50kg weight, and an adult female sheep is 60kg weight. Compared with the small tailed han sheep, the new strain sheep has the advantages that in terms of the table purpose, the figure is improved, and the milk production performance is improved. Compared with the eastfrierian sheep, the new strain sheep has the advantages that the reproductive performance is improved, the adaptation is enhanced, the new strain sheep is suitable for development and production, and the economic benefit of sheep farming is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and mainly relates to a method for breeding a new strain of sheep with both meat and milk functions.
