Research interests

As a behavioural scientist, I study behaviour as a way of measuring Animal Welfare, and to understand and solve welfare problems which involve behaviour in captive animals, particularly farmed livestock.

My research interests include:

1) Behavioural problems in pig groups: particularly

  • Social aggression (fighting and bullying), where I have long-standing collaboration with SRUC colleague Dr Simon Turner, looking for genetic and management solutions and seeking to understand how pigs assess each other during fights.
  • Tail biting. Identifying practical means to predict, detect and prevent tail biting on farm. In collaboration with Danish Pig Research Centre and Teagasc in Ireland.

2) The problem of hunger in feed-restricted broiler breeders and dry (lactating) sows. These animals have high growth potential but must be rationed to be healthy adults. Can we find diets which restrict energy to ensure good health without chronic hunger?

3) The use of technology to improve management and welfare by monitoring behaviour on-farm. Developing machine-vision approaches based on video technology to automate behaviour recording.

Selected research projects

  • Investigating how the type and quantity of food affect foraging behaviour and the neural circuits controlling feeding in broiler breeder chickens
    Does high fibre ‘bulky’, low protein or higher growth curve diets increase satiety in these feed-restricted birds? (Dr Laura Dixon, BBSRC, 2013-2017, with Roslin and Newcastle).
  • Welfare assessment techniques Obj 5 Development of ‘automatic’ assessment approaches
    Annotation of pig behaviour in video files is a pre-requisite for automation of those behaviours by technology collaborators (Scottish Government RD2.2.7, 2016-2021).
  • Improved husbandry and reduction of painful procedures  Obj 1 Food restriction in pregnant sows
    EU directives require fibre in sow diets to increase satiety. How are the industry implementing this and does it work? (Scottish Government RD2.2.8, 2016-2021).
  • Early detection of tail biting in pigs using 3D video to measure tail posture
    Tail posture changes before tail biting outbreaks. Can we detect automatically and develop an early warning system for farmers? (Dr Emma Baxter, Innovate UK Agri-Tech Catalyst with Innovent Technology Ltd, Agri-EPI Ltd, Harbro, Sainsbury’s Supermarket Ltd).

    Strategies to reduce the risk of tail biting in pigs managed on slatted floors
    Pigs need materials to root and chew but loose materials such as straw are not practical. Investigating wood and other materials. (2015-2019 Walsh fellowship with Teagasc and University of Edinburgh)
  • Helle Pelant Lahrmann
