The effects of polymorphism in the DGAT1 gene on energy balance and milk production traits in primiparous Holstein cows during the first six months of lactation

Original language description

The aim of this study was to analyze the effects and significance of DGAT1 K232A polymorphism on milk production traits ? milk yield, content of protein, fat and fat-to-protein ratio in milk during the first six months of lactation, with respect to the course of the body condition. The influence of year, calving season and month of lactation on these traits was also assessed. The investigation was conducted on 246 primiparous Holstein cows, calved from 2009 to 2011. DGAT1 genotypes were identified usingthe polymerase chain reaction ? the restriction fragment length polymorphism technique (PCR-RFLP). The A and K allele frequencies were 0.73 and 0.27. Homozygotes KK were characterized by significantly (P<0.01- 0.05) highest milk fat content during the whole observed period on average as well as in almost all individual months after parturition. Homozygotes AA reached significantly highest average milk yield in almost all observed months and in the whole observed period (P<0.01-0.05), wh
