Problems solved by technology

However, due to the low quality of mutton, the limited quantity, and the influence of factors such as poor processing and packaging, the competitiveness in the international mutton market is not strong.
The reasons are as follows: firstly, due to the large population, the stock rate of live sheep is low, which cannot meet the balance of supply and demand throughout the season; secondly, there is a lack of special meat varieties and supporting systems, such as feeding management, product processing and marketing, etc. Quite a few are from old, weak, disabled and eliminated breeds, and the quality of some lambs does not meet international standards, which affects market competition and restricts the production and development of mutton sheep

Embodiment Construction

[0013] Now with reference to the accompanying drawings, specific embodiments are described with regard to the above-mentioned method.

[0014] (1) Sheep breed selection: three excellent imported mutton sheep—German Merino mutton sheep (code-named G), hornless Dorset mutton sheep (code-named D) and Suffolk mutton sheep (code-named S), Inner Mongolia Ujimqin Banner Sheep (Code M) is an excellent domestic breed;

[0015] (2) The first-generation hybrid combination and hybridization method: a two-way fully imported hybrid combination (male parent × female parent) - G×D, G×S, D×S, D×G, S×G, S×D , and two-element mixed-breed hybrid combination (domestic Mongolian mutton sheep as recipient sheep)—S×M, D×M G×M, using superovulation technology to collect embryos, artificial insemination and embryo transfer, and house feeding after mating. Combining feeding with grazing and strengthening scientific feeding management, the offspring (F1) of dual hybrids were bred;

[0016] (3) Measure ...

Abstract

A dual-hybridizing method for increasing the quality and output of mutton includes such steps as hybridization between at least two excellent varieties of foreign meat sheep to generate the first generation hybrid meat sheep, hybridizing with native meat sheep to obtain a generation of mictic hybrid meat sheep, and secondary hybridizing combination.

Description

technical field [0001] The method of the invention relates to the improvement of livestock breeds, in particular to an improvement method for improving the quality and yield of mutton by double-crossing imported mutton sheep and Mongolian sheep. Background technique [0002] my country is a big mutton producer, especially in the past 10 years, it has gradually developed into the world's largest mutton producer. According to preliminary statistics, the mutton output in 2004 reached 3.99 million tons, ranking first in the world. However, due to the low quality of mutton, limited quantity, and poor processing and packaging, the competitiveness in the international mutton market is not strong. The reasons are as follows: firstly, due to the large population, the stock rate of live sheep is low, which cannot meet the balance of supply and demand throughout the season; secondly, there is a lack of special meat varieties and supporting systems, such as feeding management, product p...
