An index currently used to evaluate feed efficiency in cattle is the residual feed intake (RFI) whose heritability is around 0.20-0.40. Genome wide association studies (GWAS) can contribute to breeding programs aimed at improving RFI by detecting genomic regions and candidate genes that regulate it....
