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).
