Breeding method for a new multi-fetal strain of Xuhuai mountain mutton

Abstract

The invention relates to a new prolificacy strain cultivation method for Xuhuai goat meat.The method comprises the steps that on the basis of carrying out genetic determination and evaluation on individual muscle growth and development traits and reproductive performance, a conventional breeding method is utilized in cooperation with molecular marker-assisted selection (MAS) and a multi-gene pyramiding breeding composite system, individuals with the high growth speed and good carcass meat performance are selected to cultivate a high-quality paternal group, individuals with prolificacy, strong maternity and good lactation ability are selected to cultivate an ideal maternal group, a core group is built, and the new prolificacy strain with the high meat performance and reproductive performance for Xuhuai goat meat is cultivated.

Description

technical field [0001] The invention relates to a method for cultivating a multi-fetal new breed of Xuhuai mountain mutton, and belongs to the technical field of breeding new breeds of livestock and poultry. Background technique [0002] Xuhuai goat, also known as Suining white goat, belongs to the type of Huanghuai goat and is a breed with both skin and meat. It is mainly distributed in Xuzhou and Suqian along the old course of the abandoned Yellow River and counties in hilly areas. It is also raised in other areas, especially in Suining County. It is named after the most breeding and a long history of breeding. Suining white goats are known for their strong fecundity, early maturity, perennial estrus, year-round mating and lambing, large individuals, good skin quality, resistance to rough feeding, and strong adaptability. They are the famous "three sheep" in Jiangsu Province. "one. [0003] Although Suining white goat meat has the advantages of tender and juicy meat comp...

AI Technical Summary

Problems solved by technology

[0004] In recent years, the number of purebred Suining white goats has been decreasing due to the development of cross-breeding improvement work. Although the selection of its own breed has also been carried out, this selection is usually based on phenotype rather than genotype , so its selection efficiency is relatively low, and modern molecular breeding and biotechnology have not been applied to the selection of Suining white goat breeds so far.
