Genetic Basis of Wooden Breast and White Striping in Commercial Broiler Chickens

To gain insight into the genetic basis of wooden breast and white striping in broiler chickens, a genome-wide association study was conducted using a commercial crossbred broiler population (n = 1193). Chickens were evaluated for wooden breast, white striping, and body weight at 13 days and 7 weeks of age. Genotyping was performed using restriction enzyme-based genotyping by sequencing and quantitative trait loci were detected using single-SNP analysis and Bayesian multi-marker regression (BayesB).

为深入探究肉鸡木质胸肉和白色条纹的遗传基础，本研究采用商业杂交肉鸡种群（n = 1193）开展了全基因组关联分析。研究人员在13日龄和7周龄时对鸡群进行了木质胸肉、白色条纹和体重评估。基因分型通过基于限制性酶切位点的基因测序和定量性状位点分析以及贝叶斯多标记回归（BayesB）方法进行检测。
