Poultry are the most widely used animal protein source in the world: billions of meat birds are produced globally each year, using 360 million tons of feed. Within Europe, over 30,000 companies involved in the production of poultry create an annual turnover of 107 billion. However, maintaining the sustainability of the industry as it moves towards antibiotic-free production is one of the key challenges. Starting with an overview of antibiotics as growth promoters and the challenges faced as the industry moves away from their use, this book then thoroughly considers the potential of pre and probiotic additives in poultry gut health. The book: Includes thorough definitions of additives in the pre and probiotic space and examples of how they work; Addresses how to test pre and probiotics and other similar additives, and how they interact with other products, with learning from both poultry and allied sectors; Combines authors from both academic and industry backgrounds on all chapters, to ensure coverage is balanced, robust and commercially relevant. Based on the renowned World Poultry Science Association UK Branch Poultry Science Symposium 2022, this book provides a thorough and valuable contribution to the field for all involved with the nutrition and production of poultry.

Examining sustainable poultry production systems across Europe, this book contains a selected cross section of papers from the 2014 UK Poultry Science Symposium. It reviews essential topics such as resources and supply chains, the global poultry market, risk management, zoonoses and green issues. Providing a compilation of the most current research in the poultry science and production industry, this book is an important resource for both researchers and professionals.

Archaeological evidence is enriched when it is viewed against the backdrop of its natural landscape setting. This setting is not readily apparent in the lower Lea valley, where evidence for the natural topography has been cut away by quarrying and reservoir construction or buried by metres of alluvium and modern made ground. The Lea Valley Mapping Project, funded by the Aggregates Levy Sustainability Fund, has taken a geoarchaeological approach to reconstructing the past landscape and its relationship to archaeological distributions by using existing borehole information to model the buried topography and past environment of the lower Lea valley from the M25 to the confluence of the Lea and the Thames. The results place the known archaeology within its past landscape context and also predict the archaeological potential of the study area, which readers can investigate by referring both to the maps in the monograph and to the accompanying gazetteer. They can also download the interpreted geo-referenced datasets produced for the project from the ADS website. This book will be an indispensable guide not only for those wishing to know the archaeological potential and past landscape characteristics of the lower Lea valley but to anyone proposing to investigate the buried landscape in other river valleys or wanting an introduction to Quaternary deposits, environments and landscape processes in Greater London.
