Weight gain is a key performance trait for beef cat­tle; however, attention should be given to the production costs for better profitability. Therefore, a feed efficiency trait based on per­formance can be an interesting approach to improve performance without increasing food costs. To identify candidate genes and ge­nomic regions associated with residual body weight gain (RWG), we conducted a genome-wide association study (GWAS) with 720 Nellore cattle using the GRAMMAR-Gamma association test.
