Abstract excerpt
The aim of this work was to determine the effects of a growth hormone receptor (GHR) AluI polymorphism on the reproductive performance of Holstein cows. The cows (n = 94) were on the study from 3 weeks prepartum until 210 days in milk (DIM). Blood samples were collected at -21, 0, 7, 21, and 60 DIM. For GHR genotyping, DNA was extracted from blood and the presence of the alleles determined after polymerase chain...
