This study was conducted to identify gene polymorphisms and to investigate the relationships of polymorphisms with yield and composition of milk from Holstein cows. Significant relationships of growth hormone ( GH ) , leptin ( LEP ) and myogenic factor 5 ( MYF 5) gene polymorphisms with 305‐day milk yield were observed ( P < 0.01). Signal transducers and activators of transcription 5A ( STAT 5A) gene polymorphism did not show any significant relationships with investigated traits ( P > 0.05). With regard to the 305‐day milk yield, GH ‐ LV , LEP ‐ AA and AB and MYF 5 ‐ GG genotypes were found to be superior over the other genotypes. It was concluded based on present findings that GH , LEP and MYF 5 genes could be used as candidate genes for milk yield of Holstein cows.
