Dr Andrea Ellis

Senior Lecturer

School of Animal Rural & Environmental Sciences

Role

I am a part-time senior lecturer at NTU, supporting primarily Masters level Equine Nutrition and Behaviour subjects as well as leading the MSc Ethics and Consultation Module. I supervise students both in undergraduate and postgraduate Research Dissertations from equine to animal and conservation topics.

Career overview

Dr Andrea D. Ellis is a renowned equine scientist, whose early research (PhD) focused on food intake behaviour and nutrient digestion in horses and sheep, and set her on a path of becoming a specialist in equine nutrition and behaviour. After working as a Scientific Researcher in the The Netherlands at Wageningen University, for four years with a focus on nutrition and developmental bone disease and on nutrient evaluation systems for horses, she joined Nottingham Trent University as Senior Lecturer, where she led the design of an MSc in Equine Health and Welfare.

Andrea now runs her own consultation company UNEQUI, Science and Creativity. She is passionate about animal nutrition and welfare, good science and biology education. Her equine research focus has been food intake behaviour and ethological requirements, as well as behavioural markers of welfare (e.g. ridden horse pain ethogram) and changing human behaviour towards better animal welfare.  Andrea lectures and carries out research in Nutrition, Behaviour, Welfare and Ethics at various institutions, such as the University of Edinburgh and Nottingham Trent University and collaborated on the first Global Equine Nutrition Course on ANIVADO.com. She supports the European Society for Veterinary and Comparative Nutrition as executive administrator and recently enjoyed organising, co-ordinating and moderating on-line congress’s. Through the UNEQUI creativity arm, Andrea also provides illustrations, event photography, clay-art and scientific drawings.

Research areas

Subject specialism

Equine Science - Equine Health and Behaviour, Equine Nutrition and Digestive Physiology; Ethological requirements for feed intake in equines; Energy evaluation systems for horses; Animal Physiology and Nutrition, Behaviour and Welfare – Environmental Enrichment for horses; Ridden Pain Ethogram for horses;

Ethics of Animal Use, Animal-Human Relationship, Research Methods,

Research skills: Statistics made simple; Statistics on a need to know basis; Designed various course materials and consulted on ‘how to teach statistics effectively’;

Ellis, A. D., Redgate, s., Zinchenko, S., Owen, H., Barfoot, C. and Harris, P. 2015. The effect of presenting forage in multi-layered haynets and at multiple sites on night time budgets of stabled horses. Applied Animal Behaviour Science, Applied Animal Behaviour Science 171 (2015) 108-116

This is one of the few papers (possibly unique?) where complete minute by minute night-time budgets of stabled horses are recorded and their behaviour patterns are compared on different feeding systems. In addition, it preliminarily highlights the distinct behaviour patterns of two horses carrying out stereotypic behaviour and what may regulated this, once developed, form minute by minute observations.

Ellis A. D., Stephenson M., Preece M.,Harris P. 2014 A novel approach to systematically compare behavioural patterns between and within groups of horses, Applied Animal Behaviour Science 161 (2014) 60–74;

This study used an array of previously established methods simultaneously and highlights new multi-disciplinary approaches for assessing equine behaviour quantitatively, in order to better recognise changes and patterns when studying effects of treatments on small sample populations. It also leads the way in novel visual assessments/presentation of behavioural patterns.
