Determination of the association of GHR/Alul gene polymorphisms with milk yield traits in Holstein and Jersey cattle raised in Turkey
Çobanoglu, Özden; Kul, Ertuğrul; Gürcan, Eser Kemal; Abaci, Samet Hasan; Çankaya, Soner (Copernicus Gesellschaft Mbh, 2021)This research was carried out to determine the effect of a specific single nucleotide polymorphism (SNP) region in exon 10 of the growth hormone receptor (GHR) gene on milk production traits in Jersey and Holstein cows ... -
Determination of the genetic polymorphism for DGAT1 gene in Holstein, Jersey and native cattle breeds of Turkey
Gürcan, Eser Kemal; Çobanoglu, Özden; Kul, Ertuğrul; Abacı, Samet Hasan; Çankaya, Soner (Agricultural Research Communication Centre, 2019)This study was to determine the genetic polymorphism in terms of the DGAT1 gene among Holstein and Jersey and indigenous Native Black, East Anatolian Red and Grey Steppe in Turkey. The frequencies of K allele for the DGAT1 ... -
Effects of lactation month and season on test-day milk yield and milk components in Holstein cows
Çobanoglu, Özden; Gürcan, Eser Kemal; Çankaya, Soner; Kul, Ertuğrul; Abaci, Samet Hasan; Ülker, Mehmet (Agricultural Research Communication Centre, 2017)This study aims to determine the correlations between the test-day milk yield (TDMY) and the fat and protein content as well as the fat and protein yields in Holstein dairy cows and to investigate the effects of lactation ... -
Estimation of genetic and environmental parameters for milk traits in jersey cows
The aim of this study was to estimate the genetic parameters and environmental factors for testday milk yield (TDMY), lactation milk yield (LMY), 305-day milk yield (305-DMY), milk fatpercentage (FP) and milk protein ... -
