Differences in genetic diversity in Holstein cattle with high and low genetic merit

Research output: Contribution to conferenceConference paper

Abstract

Evaluations of genetic diversity in Holstein cattle based on pedigree data, indicate a decrease in genetic diversity in Holstein cattle, because of a lower effective population size and a higher relatedness compared to other cattle breeds. However, pedigree based diversity reflects only the overall genetic diversity, while for specific regions on the genome the genetic diversity might be completely different. The objective in this study was to compare genetic diversity across the genome between Holstein cattle with high and low genetic merit for milk production, using pedigree information and SNP data.
