Bingjie Li: How to define feed efficiency in dairy cattle? – in the quantitative genetics and animal breeding point of view
PhD defense, Friday 26 October 2018. Bingjie Li.
During her studies, Bingjie Li researched the genetic properties of alternative feed efficiency (FE) definitions and FE-related traits in several dairy breeds in order to investigate the possibility of including FE into Nordic dairy cattle breeding. Improving FE is expected to increase the profits of dairy farmers and reduce the ecological footprint of dairy production. Bingjie Li studied the genetic properties of two important FE traits, dry matter intake (DMI) and residual feed intake (RFI), in Holstein cows, Nordic Red cows, and Jersey cows across different lactation stages. She investigated the influences of alternative modelling methods on defining FE in dairy cattle.
The new research findings contribute to better definitions of FE in dairy cattle and provided important information for recording and selecting for FE in dairy cattle breeding programs.
The PhD degree was completed at the Department of Molecular Biology and Genetics, Aarhus University, and at the Department of Animal Breeding and Genetics, Swedish University of Agricultural Sciences, Sweden.
This résumé was prepared by the PhD student.
