This Book of Abstracts is the main publication of the 69th Annual Meeting of the European Federation of Animal Science (EAAP). It contains abstracts of the invited papers and contributed presentations of the sessions of EAAP's eleven Commissions: Animal Genetics, Animal Nutrition, Animal Management and Health, Animal Physiology, Cattle Production, Sheep and Goat Production, Pig Production, Horse Production and Livestock Farming Systems, Insects and Precision Livestock Farming.

The main theme of the Congress, 'Ethology for Health and Welfare', was chosen to reflect the prominence that applied ethology has in the field of animal welfare and to encourage the development of applied ethology in studies to promote animal health. The location of this year's Congress within the Atlantic Veterinary College at the University of Prince Edward Island has provided the focus on veterinary aspects of ethology and welfare. Applied ethology continues to develop and expand, and we have showcased recent developments in play behaviour and other key topics.
