Cattle nutrition, climate and environment

Our research aim and focus

With focus on supporting a more sustainable dairy production, the theme group develops new feeding strategies with the primary aim of improving feed efficiency, reducing the environmental impact, and reducing emission of greenhouse gases and ammonia from cattle production without impairing animal production. A key focus area is the interaction between nutrition and rumen microbiome, cattle genomics, animal health, and milk quality as well as potential downstream effects related to manure quality and management.

Our primary focus areas

  • Biological response of energy level and level of different nutrients 
  • Feed efficiency and resource utilization

  • Quantification and mitigation of enteric methane and other greenhouse gasses

  • Development of new feed additives aiming at reducing enteric methane

  • Rumen microbial ecology

  • N and P utilization, and interaction between nutrition and downstream effects related to manure management
  • Providing data and research that forms the basis for modelling nutrient utilization and excretion and the basis for national inventory models
  • Interaction between cattle nutrition and rumen microbiome, genomics, animal health, and milk quality

Our research perspectives

Quantifying and mitigating the climate impact and environmental load of cattle production is indisputable, and is addressed by the development of more sustainable cattle production systems.

These are based on new sustainable feeding strategies and nutrient standards and research-based service of the authorities concerning improvement of the nutrient utilization and reduction of the environmental- and climate impact.
