Molecular marker related to broiler chicken antibody titer, detection method and application

The invention discloses a molecular marker related to broiler chicken antibody titer, a detection method and application, and belongs to the technical field of poultry genetic breeding. The nucleotide sequence of the molecular marker is shown as SEQ ID NO.1, the 145th basic group of the nucleotide sequence is an SNP site, the site has A/T mutation, and the genotypes are AA and AT. The invention further provides a primer pair and a detection method for detecting the molecular marker, and experimental results show that the nucleotide sequence of the molecular marker can be efficiently, sensitively and quickly detected by utilizing the detection method so as to screen and identify high-antibody-titer broiler varieties. The broiler chicken with high antibody titer can be effectively screened, a new technical scheme is provided for genetic breeding of the broiler chicken, and the method is suitable for large-scale popularization and application in the broiler chicken breeding industry. 本发明公开了一种与肉鸡抗体滴度相关的分子标记、检测方法及
