Abstract excerpt
The milk fat-to-protein ratio (FPR) is an important indicator of milk quality and a useful biomarker of metabolic status in dairy cows. This study used functional single-step genome-wide association analysis (ssGWAS) incorporating performance records from 502,781 first-parity Iranian Holstein cows and SNP genotypes from 2,187 Holstein bulls to investigate the genomic architecture underlying FPR variation in this...
