Genomic analysis of Canadian Simmental Population
Delivering genomic technology to Canada’s beef industry has been of great interest in recent years. The Genome Canada project was an initiative to achieve this goal and included the identification of key ancestors through pedigree analysis for sequencing and genotyping. The Canadian Simmental Association has recently invested in both phenotyping and genotyping more Simmental beef cattle. It is of interest to identify key ancestors through genomic analysis and compare to animals previously selected using pedigree. A genomic relationship matrix was constructed and the top contributing animals were identified and over 46% were similar to the previous study using pedigree alone. Also, breed composition study in two commercial populations, revealed Simmental and Angus as the major breed with 45.27% and 38.69%, respectively.
