Breeding method of new variety of western Henan milk sheep

The invention relates to a breeding method of a new variety of western Henan milk sheep, and belongs to the technical field of animal breeding. According to the method, western Henan fat tail sheep is taken as a female parent, lacoenn sheep is taken as a male parent, grading hybridization is carried out for two generations, Dongfengsheng sheep is taken as a terminal male parent, hybridization is carried out, cross-crossing fixation is carried out after optimization, and a new variety of western Henan milk sheep is cultivated. According to the method, a traditional breeding technology and a molecular breeding technology are combined, good genes such as Dongfenglien sheep and lacohn sheep which are large in size, multiple in fetus, good in milk performance and thin in fat tail are polymerized into western Henan fat-tail sheep through a gene polymerization breeding technology, and meanwhile the characteristics that the western Henan fat-tail sheep is rapid in growth and development, high in adaptability and the
