Ilias Kyriazakis is the Professor of Animal Science at the Institute for Global Food Security of Queen’s University Belfast. He is a veterinarian by training who specialises in the effects of animal management on their performance, the ability to cope with challenges, such as pathogens, and their environmental impact. He has worked with a variety of animal species ranging from mice to cows, but more recently his research has focused on pigs and poultry. His recent work in poultry addresses: 1) the effect on nutrition on the ability of birds to cope with pathogens, such as coccidian; 2) the use of alternative and home grown feeds in poultry systems and 3) the development of methods to assess the environmental impact of local and global poultry systems. His team was responsible for the assessment of the environmental impacts of the UK poultry systems and the identification of hotspots responsible for such impacts. Professor Kyriazakis is the recipient of several awards, including the Leroy Award by European Federation of Animal Sciences (EAAP) for International Excellence in Animal Science, and Fellow of national and International bodies.

Maureen BAIN

Over the past 30 years I have developed an interdisciplinary line of research developing novel methods for assessing egg and eggshell quality and have been involved in a number of EU and BBSRC funded collaborative projects concerned with improving the quality and safety of eggs. My expertise and research profile in egg quality research and avian reproduction has led to the establishment of longstanding partnerships with industry stakeholders including breeding companies in both the egg and meat sectors of the industry. I have supervised many undergraduate and post graduate research projects, published over 140 scientific papers, written numerous book chapters and delivered talks on the subject of egg quality through various media both nationally and internationally. I am currently a council member of the UK branch of WPSA, and British Poultry Science Ltd and, until 2018 was the chairperson of the European Poultry Federation WG4 (Egg and Egg products). Through these roles I have been able to influence policy and provide support for early career researchers and workers involved with the poultry industry.


Dr N.J. Daghir received his BSc from the American University of Beirut (AUB) in 1957 and was immediately appointed by AUB to provide agricultural extension services to the central and northern Beqa’a region in Lebanon, to where he introduced commercial poultry production. He earned both his MSc and PhD degrees from Iowa State University in 1959 and 1962, respectively. In 1962, he helped establish the Lebanese branch of the World Poultry Science Association and became president of that branch until 1984. During the same year, he started his teaching and research career at the AUB. In 1967, he was promoted to associate professor and in 1975 to full professor. He has served as adviser for over 50 MSc graduate students, many of whom have later received PhD degrees from US universities and are now occupying key positions all over the world. Dr Daghir is a member of several professional and honorary organizations and has served as a consultant to poultry companies in Lebanon, Jordan, Syria, Iraq, Iran, Egypt, Kuwait, Tunisia, Saudi Arabia and Yemen. He has participated in lecture tours on poultry production in countries all over the World and has served on special assignments for several organizations such as the Food and Agriculture Organization of the United Nations, American Soybean Association, and the Kuwait Institute of Scientific Research. He also served on many international, regional and national committees such as the International Standing committee of WPSA on Nutrient Requirements and the committee of the International Union of Nutritional Sciences (commission VI, committee 8) on Nutrition of Poultry. Dr Daghir has had over 100 articles published in scientific journals and the proceedings of international meetings as well as several chapters in books and compendia. The second edition of his book “Poultry Production in Hot Climates” was published by CABI in 2008. His research has covered a wide range of subjects, such as factors affecting vitamin requirements of poultry, utilization of agricultural by-products in poultry feeds, nutrient requirements of poultry at high-temperature conditions, seeds of desert plants as potential sources of feed and food, and plant protein supplements of importance to hot regions. His research has received funding from the US National Institutes of Health, the International Development Research Centre of Canada and the Lebanese National Council for Scientific Research. He has served as Chairman of the Animal Science Department, Associate Dean and Dean of his Faculty at AUB.

Bertrand MEDA

After an engineer degree and a Ph.D in animal sciences, I joined in 2011, the INRAE unit “Avian Biology & Poultry Research Unit” (UMR BOA) located near Tours. In the AliSÉ team (Animal Feeding and Livestock Systems), my research is focused on the consequences of new feeding strategies and the use of new feed ingredients on the sustainability of broiler production systems, with an emphasis on the issue of protein self-sufficiency in France/Europe. I also started to work on the evaluation on the services provided by poultry production, using systemic approaches. I work with several nutritionists from INRA as well as from private companies, and use modelling approaches at different scales (animal, farm), such as Life Cycle Assessment (LCA) to evaluate the environmental impact of poultry production systems. I am currently taking part in several national and international projects on poultry nutrition. Especially, in the European H2020 Feed-a-Gene project (, I am working on the development of precision feeding in poultry.

Dr. Martin Zuidhof is a Professor of Precision Feeding & Poultry Systems Modeling at the University of Alberta. Martin Zuidhof has been studying Broiler Breeders for over 25 years. His team developed and patented a precision feeding system to feed each bird the right amount of the right feed at the right time. In addition to its commercial potential, the system doubles as one of the best poultry research tools in the world. Dr. Zuidhof‘s goal is to revolutionize the way the world studies and feeds broiler breeders. Dr. Zuidhof is academic leader of the Poultry Innovation Partnership (PIP), a unique collaboration between the University, Government, and the poultry industry. The PIP is committed to relevance and excellence in research, learning, and extension, and it plays an important role training the next generation of leaders in the poultry industry.
