Embodiment 1

[0047] Example 1: A breeding method for a new variety of Huanghuai mutton sheep, through three types of interbreeding innovation (2003-2010), group locking and cross-fixation (2011-2017) and group expansion breeding (2018 to early 2019). developed in stages.

[0048] (1) Hybrid innovation stage

[0049] Taking Dorper sheep as the male parent and purebred Small-tailed Han sheep or small-tailed Han sheep as the female parent, crossbreed to obtain the first generation of hybrid Du Han sheep F 1 ; Then take the Dorper sheep as the male parent, and cross a generation of Du Han sheep F 1 As the female parent, crossbreed to obtain the second-generation Duhan sheep F 2 ;

[0050] (2) Transversal fixation stage

[0051] Hybrid second-generation Du Han sheep F 2 Self-crossing, and then after 3-4 generations of cross-crossing, optimization;

[0052] (3) Group multiplication stage: Heterogeneous matching is carried out according to the disadvantages of the group, and then multiplica...

Abstract

The invention relates to a breeding method of a new breed of Huanghuai mutton sheep. The method includes taking Dorper sheep as male parents and taking small tailed han sheep or small tailed han sheephybrid sheep as female parents to perform hybridization; and breeding the new breed of mutton sheep which are high in reproduction rate, fast in early growth rate, high-quality in meat and suitable for breeding at Huanghuai areas through hybrid innovation, crossing fixation and group expanding propagation. The weights of the adult rams of the new breed Huanghuai mutton sheep can reach 98.1 kg, and the weight of the ewes can reach 71.7 kg; the fattening weights of 6-month-old rams and ewes are respectively 58.50 kg and 52.45 kg; the dressing percentage of the 6-month-old fattening rams and ewes are respectively 56.02% and 53.19%; and the annual lambing rate of the ewes is 252.82%, and the number of weaned lambs provided by the ewes per year is 2.38. Through the on-site examining and approving of National Livestock and Poultry Breed Committee in 2019, powerful support can be provided for the enhancement of self-sufficiency rate of core provenance of Chinese mutton sheep, the developmentquality benefit and competitiveness of mutton sheep breeding industries and the development of modern mutton sheep industries; and therefore, the method has good economic and social benefits.

Description

technical field [0001] The invention relates to a method for cultivating a new breed of mutton sheep, belonging to the field of animal breeding, and in particular to a method for cultivating a new breed of meat sheep adapted to the Huanghuai region. Background technique [0002] A perfect breed breeding system is the prerequisite for the industrialization of mutton sheep, and together with forage resources, environmental conditions and traffic location constitute the necessary conditions for mutton sheep breeding. At present, the breeding system of mutton sheep breeds in China is to breed specialized breeds (strains) for meat, which conforms to the traditional breeding mode. The development of the modern mutton sheep industry must have two essential conditions: high reproductive rate and fast early growth rate. However, a high reproductive rate and a fast early growth rate are two opposite indicators in the biological field. A high reproductive rate has a slow early growth ...
