Problems solved by technology

[0006] However, for the lambing traits of goats, the number and types of genes involved in the regulation are many, and the interaction between genes on the lambing traits is complicated and the mechanism of influence is complex. Therefore, it is not possible to guide trait improvement based on the variation of a single gene.
At present, there are commercial SNP chips available for goats on the market, which can realize the screening and identification of genome-wide molecular markers through genome-wide association analysis, but the cost of chip detection is too high, which is not conducive to large-scale detection applications in actual breeding

Abstract

The invention discloses molecular markers related to lambing traits of a Nubian goat and combined application of the molecular markers. The molecular markers related to the lambing traits of the Nubian goat are a group of molecular markers which are respectively located in a BMPR1B gene, a BMP15 gene, a GDF9 gene and an FSHR gene. According to the invention, the lambing traits of the Nubian goat can be rapidly predicted by utilizing the molecular markers, improvements on the lambing traits of the Nubian goat can be realized, and the breeding efficiency of the molecular marker-assisted selection can be greatly improved.

Description

technical field [0001] The invention relates to a group of molecular markers and their combined application, in particular to a molecular marker related to the lambing traits of Nubian goats and their combined application. Background technique [0002] Nubian goats are native to Egypt, Libya, the United Kingdom, the United States and other countries in northeast Africa, and are distributed in Eastern Europe and South Africa. my country introduced breeding in 1995 to improve domestic goats. Nubian goats are large in size, resistant to rough feeding, strong in adaptability, fast in growth and development, strong in fecundity, and stable in genetic performance. They are gradually loved by people because of their tender meat and no smell. In terms of production performance, rams can start breeding at the age of 8-10 months and ewes at the age of 6-7 months, with an annual output of 1.7 litters, and the lambing rate is generally 193% for the first birth. The female lamb weighs ...
