Abstract

The invention discloses a SNP molecular marker related to bovine growth traits. The nucleotide sequence of the molecular marker is shown in SEQ ID NO.1, located at the 214th base in SEQ ID NO.1; SEQ ID NO.1 The base in ID NO.1 is A or G. The invention provides a SNP molecular marker related to the growth traits of cattle, which enriches the genetic resource library of molecular markers for buffalo breeding by screening the molecular marker sites related to the growth traits of buffaloes. Using this molecular marker to breed Mora buffalo greatly increases the accuracy of the selection of buffalo growth traits. Individuals carrying this dominant allele should be retained in breeding, which will help improve the body length traits of the cattle population. as potential genetic markers.

Description

technical field [0001] The invention relates to the technical field of cattle breeding, in particular to a SNP molecular marker related to cattle growth traits and its application. Background technique [0002] Cattle breeding work refers to any work that can improve the quality of cattle from the genetic structure and increase the quantity and quality of products. The breeding of cattle breeds is to consolidate and improve excellent genes in the group, thereby creating a product with superior production performance. individuals, and the process of expanding the number of good individuals. Genetic improvement of economically important traits in cattle herds. Traditional breeding methods mainly rely on phenotypic selection without understanding their genetic background. [0003] Now, breeders have gradually transformed the improvement of target traits from phenotype selection to genotype selection theory, making full use of molecular breeding methods to carry out selection ...
