Margot Slagboom: Breeding for organic dairy production – optimization of breeding goals and breeding strategies

PhD defence, Friday 22 March 2019. Margot Slagboom.

Margot Slagboom

During her studies, Margot Slagboom researched the value of specific breeding lines for organic dairy cattle. Current breeding practices in organic production are inconsistent with what organic regulations state about breeding, which suggests the need for alternative breeding practices. Margot looked at the effect of implementing different breeding goals such as breeding goals based on economic models, preferences of farmers, and relatedness to organic regulations and principles. In addition, Margot researched the effect of certain breeding strategies, such as the implementation of an environment-specific breeding goal, the usage of embryo transfer, and the selection of breeding bulls that originate from a conventional environment.

The new research findings can be used as valuable input for the practical implementation of breeding lines specifically for organic dairy production.

The PhD degree was completed at the Centre of Quantitative Genetics and Genomics, Department of Molecular Biology and Genetics, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
