Relationships between polymorphisms of growth hormone, leptin and myogenic factor 5 genes with some milk yield traits in Holstein dairy cows

Abstract: 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 (MYF5) gene polymorphisms with 305‐day milk yield were observed (P < 0.01). Signal transducers and activators of transcription 5A (STAT5A) gene polymorphism did not show any significant relationships with investigated traits (P > 0.05). With regard to the 305‐day m… Show more

“…It is known that the level of milk productivity is a polygenic trait controlled by various genetic loci (Dybus et al, 2004;Singh et al, 2014), some of which are already known (Singh et al, 2014;Khatami et al, 2005), and some are only classified as candidate genes (Viale et al, 2017). Based on literature data, the following economically valuable traits gene loci were selected for our work: kappa-casein (CSN3) (Chasovshchikova et al, 2017), beta-lactoglobulin (LGB) (Di Gregorio et al, 2017), prolactin (PRL) (Chasovshchikova et al, 2017), somatotropin (GH) (Akyuz et al, 2015;Metin Kiyici et al, 2019), thyroglobulin (TG5) (Zhang et al, 2015).…”

“…Research focuses on analyzing the relationship between the values of these traits and polymorphic variants of different genes. The genes encoding different proteins, such as milk proteins, enzymes involved in the metabolism of fatty acids, proteins binding and transporting fatty acids, some hormones, transcription factors and many others are analyzed in this aspect [Szewczuk et al 2011, Cieślińska et al 2019, Thuy et al 2018, Kiyici et al 2019.…”
