SNP molecular markers related to milk yield traits of dairy goats, liquid phase chip prepared from SNP molecular markers and application of liquid phase chip

Abstract

The invention provides SNP molecular markers related to milk yield traits of dairy goats, a liquid phase chip prepared from the SNP molecular markers and application of the liquid phase chip, and belongs to the technical field of molecular biological SNP technologies and chips. The invention provides the SNP molecular markers related to milk yield traits of dairy goats. The SNP molecular markers comprise the following cases: 1) one or more of the following 83 SNP molecular markers: SNP molecular markers DGHMS01 to DGHMS83; and 2) complementary sequences or homologous sequences of the SNP molecular markers in the case 1). A molecular probe set is designed according to the SNP molecular markers, and the liquid phase chip is prepared by using the molecular probe set. The milk yield of the dairy goats is detected by adopting the liquid phase chip, and result clustering analysis, principal component analysis and character statistical results show that the 83 molecular markers are closely related to the milk yield traits of the dairy goats. Therefore, the molecular probes are used for detecting the milk yield of the dairy goats and can be used for screening or identifying high-yield milk goat varieties.

Description

Technical field [0001] The present invention belongs to the field of molecular biological SNP techniques and chip technology, which relates to a SNP molecule marker and a liquid phase chip and application prepared therebetween with milky lamb produced. Background technique [0002] The milk goat industry is an important part of the development of my country's dairy industry. With the rapid temperature rise of the goat milk consumption market, the development of my country's milk goat industry is booming. Goat milk has become the second largest milk in my country. At present, the stock of Chinese milk goat is about 1.3 million, and the lact milk lamb is approximately 7.9 million, the total output of Goat milk is about 1.75 million tons, accounting for about 4.5% of fresh milk production. At the same time, the milk goat industry is moving rapidly from the traditional milk mountain farming model to modernize, intensive, standardized, and diverse quality efficiency mode. Goat milk is...

AI Technical Summary

Problems solved by technology

At present, the selection technology of dairy goats in my country is backward, and the sheep can only be bred to more than 12 months of age. After the lambs are bred and have milk, the quality of the lambs can be judged by the milk production, which makes the selection efficiency of dairy goat farms low, and the renewal and elimination rate is low. , and greatly increased the cost of feeding large-scale farms
