一种检测SNP分子标记的试剂盒在高产奶牛筛选中的应用
By using a kit to detect SNP molecular markers, superior alleles are selected and the frequency of the AG genotype is increased generation by generation. This solves the problem of difficulty in increasing the total milk yield of dairy cows during lactation in traditional methods, realizes efficient molecular marker-assisted breeding, and improves the production performance and economic benefits of dairy cows.

AI Technical Summary
Traditional phenotypic selection methods are difficult to increase the total milk yield of dairy cows during lactation in the short term, are greatly affected by environmental factors, and genome-wide association studies have insufficient analytical power when the sample size and density are insufficient, making it difficult to accurately locate the genes that affect the traits.
To develop a kit for detecting SNP molecular markers, by selecting dominant alleles, increasing the frequency of the AG genotype generation by generation, eliminating the GG genotype, retaining the AG genotype in breeding cattle, and using primer pairs for PCR amplification and sequencing to determine the SNP sites, thus achieving efficient and accurate molecular marker-assisted breeding.
It has accelerated the progress of cattle genetic improvement, increased the total milk production of breeding cattle during lactation, improved economic benefits, and bred superior breeding cattle with high milk production traits.
