Breeding Icelandic Cattle with genomic methods

PhD defence, Tuesday 1 November 2022. Egill Gautason.

During his PhD studies, Egill Gautason studied breeding of Icelandic Cattle. Egill Gautason researched the relationship of Icelandic Cattle to other breeds, inbreeding in Icelandic Cattle, assessed benefits of using genomic information for selection (so-called genomic selection), and compared methods to manage inbreeding in the breeding program.

The findings showed that Icelandic Cattle is mostly related to Nordic traditional cattle breeds and can benefit from genomic selection. The research also identified efficient methods to control inbreeding in the breeding program. The breeding program of Icelandic Cattle is currently using the results to implement genomic selection.
The PhD study was completed at the Center for Quantitative Genetics and Genomics, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
