This book focuses on animal nutrition strategies using various feed additives to enhance nutrient digestibility and utilization, modulate the antioxidant capacity, mineral status, immunity, and gut and/or rumen microbiota in livestock. This results in improvements in their growth, performance and production parameters, as well as the quality of animal products.

Les terres consacrées à l'élevage couvrent près de 4 millions d'hectares dans le monde, soit 80 % des surfaces agricoles et la demande en produits animaux est en hausse constante, notamment dans les pays tropicaux. D'une importance capitale dans le développement durable des régions chaudes, la production fourragère est le principal levier de la productivité des systèmes d'élevage. Elle joue également un rôle essentiel pour les systèmes qui allient productions végétales et animales et de nombreux systèmes agroécologiques intègrent des plantes fourragères. La première partie de cet ouvrage est destinée à guider le choix de plantes fourragères et de leurs cultures (diversités des plantes, des usages, des milieux et des types d'élevage). La seconde partie est consacrée aux techniques de culture, à la gestion des fourrages, à la valorisation des ligneux, à la production de semences et à l'économie de ces productions. L'ouvrage est accompagné d'un cédérom qui comprend des études de cas originales, des textes et des photos complémentaires, une bibliographie. Cet ouvrage de synthèse s'adresse aux éleveurs, agronomes, techniciens, professionnels des productions animales et fourragères.

Volume I of this series compiles the science-based consensus documents of the OECD Task Force for the Safety of Novel Foods and Feeds from 2002 to 2008. They contain information for use during the regulatory assessment of food/feed products of modern biotechnology, i.e. developed from transgenic crops. Relevant information includes compositional considerations (nutrients, anti-nutrients, toxicants, allergens), use of the plant species as food/feed, key products and components suggested for analysis of new varieties for food use and for feed use, and other elements. These documents should be of value to applicants for commercial uses of novel foods and feeds, regulators and risk assessors in national authorities for their comparative approach, as well as the wider scientific community.

Antimicrobial therapy is a key factor in our success against pathogens poised to ravage at risk or infected individuals. However, we are currently at a watershed point as we face a growing crisis of antibiotic resistance among diverse pathogens. One area of intense interest is the impact of the application of antibiotics for uses other than the treatment of patients and the association with such utilization with emerging drug resistance. This Research Topic “Low dose antibiotics: current status and outlook for the future” in Frontiers in Microbiology: Antimicrobials, Resistance and Chemotherapy details various aspects of the wide ranging effects of antimicrobial therapy from areas such as the regulation of host responses tomodulation of bacterial virulence factors to acquisition of antibiotic resistance genes.
