Research projects running in 2020 include:

Supporting the transition from colony cages to cage-free systems. With Dr Siobhan Abeyesinghe and Dr Kate Norman, 91°µÍø. A project to support a large commercial producer in making the transition to cage-free systems, whilst protecting and enhancing bird welfare. 

Improving the welfare assessment of broiler chickens. With Dr Siobhan Abeyesinghe 91°µÍø and Dr Sophie Elwes, RSPCA. A vital project to evalute the robustness, health and overall welfare of emerging breeds of broiler chicken, funded by the Open Philanthropy Project. Alongside assessing various breeds of bird we will validate a behavioural assessment protocol to be used for future assessments for inclusion in the RSPCA Broiler Breed Welfare Assessment Protocol.

A formal analysis of behavioural structure as a tool to assess the impact of chronic equine disease.  Equine PhD studentship funded by the Horse Trust, with Freddie Daw, Charlotte Burn, Ruby Chang.  The impact of chronic conditions such as sweet itch and gastric ulceration on equine welfare will be assessed using subtle behavioural analysis. Is the horse sleeping normally? Is the behaviour fragmented? Are some activities delayed to prioritise shorter-term needs?

Social buffering in horses. Equine PhD studentship with Claire Ricci-Bonot, Daniel Mills and Teresa Romero, University of Lincoln. The role of social support in reducing harmful stress responses in horses. 

Developing objective, robust, real-time animal welfare measures for the Australian meat industry.  A project led by Dr Cameron Clark and Dr Sabrina Lomax, University of Sydney.  Analysis of behavioural changes in beef cattle from birth to slaughter will be undertaken using cutting edge,robotic and ear-tage based technologies. The project will determine which behavioural changes predict or are associated with changes in health or welfare.  The aim is to devise a set of objective protocols for industry to ensure a high welfare level for each animal in the herd.

Smart Farming - Monitoring the Health of Chickens.  With Maja Makagon, University of Davis, California. The aim of this project is to develop and and validate small, bird mounted acoustic sensors and complementary analysis systems for monitoring changes in the health, welfare and locations of individual birds housed in commercial flocks. Funded by University of California, Agriculture and Natural Resources High Risk/High Reward Program. 

Patterns of Sleep Behaviour in Chicks. With Lorna Wilson, University of Bath. The aim of the project is to describe and quantify patterns of sleep behaviour in chicksand relate these patterns to other indicators of welfare. Funded by M2D (models to decisions).

• Assessing and Improving Animal Welfare

  

  Genetics and management can greatly affect the welfare of farm, laboratory, companion and wild animals. We aim to improve animal welfare by understanding how human activities and management practices affect the welfare of animals that are kept, killed or otherwise impacted by humans. Comparative research can identify practices that generally elicit poor or good welfare outcomes, providing evidence that can be used to support initiatives to improve animal welfare.

• Breeding for better broiler welfare: balancing sustainability, economic and consumer preferences

  

  We aim to provide a comprehensive analysis of the impacts of, opportunities for and barriers to shifting UK chicken meat production towards slower-growing, better welfare broiler breeds.

  Multiple breed comparison studies have shown that slower growing broilers have better welfare outcomes, in terms of both health and natural behaviour, than traditional fast growing breeds.

• Development of welfare assessment protocols and technology

  

  Assessment of animal welfare is continually being improved using new insights in animal behaviour, non-invasive physiological methods, animal-environment interactions, and novel monitoring systems for animal responses and behaviours. 

  Some of our work aims to develop a more fundamental understanding of which measures (e.g. behaviour, activity, posture etc) should most appropriately be targeted with sensor technology. However, technology is not always feasible (or even desirable) in some sectors, so we develop welfare assessments that are valid and practical in whatever context they are needed and tailored to the specific welfare aim.

• Ethics of animal use and management

  

  Animal welfare issues often arise when there are conflicts of interest between humans and animals. This poses challenges around whose interests to prioritise, and what actions can be taken to produce the best moral outcome. The needs and wants of human, animal, and even environmental stakeholders must be understood and evaluated to decide what is the right course of action, but different ethicists and stakeholders may disagree about the conclusions of any ethical analysis. For example, unnecessary suffering must not be caused to legally protected animals, but what counts as ‘suffering’, when is it really ‘necessary’, and which animals should be protected? Evidence must be gathered and some consensus must be agreed upon as to weight the different possible actions.

• Fundamental understanding of welfare

  

  Animal welfare refers to animal feelings, health, and environmental suitability. These projects explore which animals are sentient and what feelings they have, and how behaviour, health, environments, and welfare interrelate. We use a wide range of techniques to investigate these fundamental questions, each of which is tailored to the particular hypothesis and species involved. Emotions are subjective (private) to the individual experiencing them, which makes them challenging to investigate scientifically.

• Implications of mare life history and mare-foal attachment for mare welfare at weaning - a pilot study

  

  While the welfare effects of weaning are well documented for foals and young from many species, the impact on mares are understudied. Here, we look at whether mare life history (e.g. number of previous foals) and degree of attachment to their foals help explain the varying responses of mares when they are separated from their foals, in order to improve their welfare at weaning

• Objective assessment of the quality of life of equines with pituitary pars intermedia dysfunction

  

  Pituitary pars intermedia dysfunction (PPID) is a common disease of older equines affecting >25% of animals over the age of 15 years. It has various associated clinical signs that could impact quality-of-life (QoL) including the painful hoof condition laminitis, weight loss and lethargy. Owners frequently mistake some of these clinical signs as being associated with ageing and not important enough to seek veterinary advice. Additionally, owners face increased physical care burden (time, money and physical exertion), along with increased emotional burden such as a changed mental state caused by affected animal encountering challenges that require additional care.
