Updated: April 2026

Project overview

Project start: April 2026 Ending: March 2028
Project manager: Adrien Kroese

Global goals

  • 3. Good health and well-being
  • 9. Industry, innovation and infrastructure
  • 17. Partnerships for the goals

Short summary

We use 3D cameras and computer vision to assess rumen fill [UE1.1](an indicator of how much cows have eaten) and link its dynamic to subclinical signs of disease. The project is a collaboration between SLU, DeLaval and Högskolan Dalarna.

I. Technical development

Produce tools that are able to segment the paralumbar fossa on 3D images and compute curvature features that best reflect rumen-fill state. Follow curvature dynamically to estimate rumen contractions.

II. Link with health

Look for indicators for subclinical cases of diseases, for example blood markers, as well as recorded treatments. Assess the link between rumen-fill dynamic and health.

III. Proactive monitoring

Deploy automated rumen-fill scoring in the barn and use it to identify cows at risk or that already show signs of compromised health or welfare.
