Data and Modelling
The research group for Data and Modelling was established by merging the groups (Herd “Management and Animal Housing” with the VetStat group.
We collect and utilize data to discover and disseminate knowledge about management, antimicrobial usage and housing of animals to improve their performance, health and welfare in a sustainable manner to improve the quality of animal and human life. As part of the Vetstat cluster, we contribute to the veterinary contingency and communicate its results in Danish to farmers and veterinarians.
The group is exploring the field of Precision Livestock farming and uses sensor technologies and data driven methods to optimize animal performance, welfare and support farmers in making sustainable decisions. Overall, the group has a large international network and takes part in several EU projects.
The group collaborates with industry and private companies in almost all its research projects and makes extensive use of own research in teaching.
