Estimation of genetic parameters and genome-wide association study for carcass traits in native chickens.

ABSTRACT:

Objective

Global consumption for chicken meat is steadily increasing. Carcass traits (e.g., slaughter weight [SW], eviscerated weight [EW]) are important economic traits for the meat production in chickens. Detection of genetic variants for these traits contributes to elucidating the genetic mechanism and accelerating genetic improvement.

Methods

In this study, we performed a genome-wide association study on SW, EW, and thigh muscle weight (ThW), as well as the relative weight of these traits in 565 Sanhuang (SH) chickens. Additionally, genetic estimation has been conducted based on wholegenome variants for carcass traits. Finally, we compared the expression abundance of candidate genes to validate the function on carcass traits.

Results

Except the percentage of SW (S
