Описание: Dr. Dunn is a Reader/Principle Investigator at The Roslin Institute, University of Edinburgh. Dr. Dunn’s long term interest has focused on understanding how food, light and behaviour control reproduction and how the oviduct contributes to the formation of eggs. As breeding goals and consumer awareness evolved, his research further developed to include the relationship between long periods of reproductive activity and osteoporosis and, the use of egg peptides as antimicrobials. Taking advantage of advances in genetics and genomics to develop traditional or marker assisted selection strategies, Dr. Dunn aims at tackling problems as diverse as osteoporosis, antimicrobial activity of egg white and shell quality in laying hens, as well as polyfollicular ovaries in broiler breeders. Furthermore, in the context of tailored livestock management (precision agriculture), the interactions between nutrition, physiology and genetics have become even more relevant. Feeding is a complex system dictated by needs (growth vs reproduction), genetics (broilers vs layers) and resources availability (diet composition) and, Dr. Dunn’s recent work shed further light on our understanding of satiety, especially in the control of food intake in birds.
