Poultry are the most widely used animal protein source in the world: billions of meat birds are produced globally each year, using 360 million tonnes 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. 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.
Canadian historian Margaret Derry examines the evolution of modern animal breeding from the invention of improved breeding methods in 18th-century England to the application of molecular genetics in the 1980s and 1990s.

Due to the wide acceptance of poultry meat and eggs, poultry farming is the fastest growing global livestock industry. Nutrition plays a vital role in economic production and the maintenance of proper poultry health. Therefore, there is a great need to update balanced nutrient requirements for new breeds, utilize alternative feed resources, evaluate newer feed additives to optimize production while excluding antimicrobial feed additives and maintain overall health. The first section of this book contains six chapters that discuss the utilization of unconventional feeds, nanominerals to reduce mineral proportions in diets, and water intake affected by environmental temperature. The second section contains six chapters that describe proper nutritional management to improve gut health and immunity, the prevention of common diseases, and the amelioration of heat stress in poultry.
Vol. 5 includes a separately paged special issue, dated June 1926.
Animal production is constantly changing. Over recent years, feed costs have increased significantly. Furthermore, today more emphasis is being placed on the health and welfare of production animals and birds, and in particular to the risk of zoonoses and potential food scares. The pig and poultry industries must now address not only the costs and efficiency of production, but also the impact of health and disease to both animals and the consumer. This edited collection of papers is taken from a series of seminars that brought together some of the world's leading authorities in the field of pig and poultry nutrition, health and production. The fundamental theme is to address the issues of nutrition and health, and in particular to cover the interactions and potential conflicts between the two. The importance of digestive function and the influence of nutrition on health and disease are covered in-depth. Strategies to combat salmonella and mycotoxins are also discussed. 'Formula for the future: nutrition or pathology' is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences.
This Special Issue presents high-quality research papers as well as review articles addressing recent advances in the use of marine bioactives in animal nutrition. The marine environment constitutes a relatively untapped source of biologically active compounds that can be applied in various areas, such as improvement of animal performance, health maintenance, and disease prevention. Numerous marine-based compounds isolated from marine organisms (especially seaweeds) have diverse biological activities, including antioxidative, anti-inflammatory, antibacterial, antifungal, and antiviral activities that can be beneficial to animal health. Additionally, the application of marine bioactives as feed additives can increase the nutritional value of products of animal origin. In this Special Issue, the main attention was focused on seaweeds and their application in poultry (laying hen and broiler chickens) and pig feed. The suitable processing of marine resources required for their optimal use as feed/feed additives was underlined. The contained publications present scientific evidence for the use of various seaweeds as feed additives that improve health (enhanced immunity, prebiotic effect), growth performance, and production. Inclusion of this unconventional material in animal nutrition can enrich products with active compounds, such as micro- and macroelements, polyunsaturated fatty acids, and pigments which are beneficial for consumers.
