Research Interests

Dr Carol-Anne DuthieMy research interests focus predominantly on understanding and optimising the productive efficiency of ruminant production systems (mainly beef and sheep, but also dairy). My key interests include:

  • Optimising feed efficiency of production systems.
  • Characterising greenhouse gas outputs from ruminant production systems.
  • Reducing the environmental impact of beef production systems (improved efficiency, mitigation strategies).
  • Precision livestock farming solutions across and range of production systems (intensive through to extensive systems). My work involves the development and use of technology to measure and report important characteristics of individual animals and their environment. This is essential to optimise health, welfare and productive output. I am also interested in combining technologies and integrated data streams to develop appropriate decision support platforms. A large proportion of my work involves collaborating with industry.
  • Interest around optimising quality of the final product (carcass quality, sensory quality and nutritional value).

Research Projects

  • Enhanced Monitoring systems for improved health management of dairy-bred beef youngstock (AHDB Beef and Lamb, 2016-2020).
  • Novel animal-mounted sensor technology to improve efficiency and sustainability (Sustainable Agriculture Research and Innovation Club: BBSRC, ESRC, NERC, 2017-2018).
  • Geolocation tracking of extensive livestock systems (Innovate UK, 2016-2017).
  • Precision Beef (Innovate UK, 2015-2018).
  • Beef Monitor (Innovate UK, 2014-2018).


  • Lecturer to SRUC’s undergraduate courses in Agriculture.
  • Co-supervisor of SRUC PhD Students.
  • External advisor for University of Edinburgh PhD students.
