Short summary
This study aimed to detect a potential association between GHR/AluI polymorphism and milk yield and milk composition traits in dairy cows raised in commercial herds using the PCR-RFLP assay. In conclusion, the GHR gene should be regarded as potential candidate genes in marker-assisted selection programs to improve the performance of milk and related traits in Turkey dairy cattle populations.
