J.L Peyraud INRA Perspective of Livestock production 2050 Food Meat: +70% (465 Mt) Milk: +60% (1045 Mt) Eggs: +60% (110 Mt) Societal Challenges Livestock Production: ATF vision Resource Efficiency Healthy livestock and People Responsible Livestock Production ATF vision: Livestock, the key in a Circular bio-economy Public goods Plant production (annual crop,
grassland) Soil Public goods Bio refinery Animal production Soybean meal Manures Feed Agro industry By products Food Mineral fertilizer

Using of marginal land not able to produce plant products for human Grasslands and rangelands : 73 millions ha (40% European AA) Productivity vs provision of services Livestock production is required for an efficient use of land What are the responses curves in various territories/countries ? Improving synergies considering local contexts Livestock regulates the ecological cycles Reduction of the use of mineral fertilizers 1.8 Mt N vs 2.1 Mt for mineral fertilizers and 310 kt P vs 286 t for mineral fertilizers Reduction/ utilisation of gas losses DSS for improving use of liquid manure Role of manure on soil fertility Soil physical properties and soil microbitoa
(specific and functional biodiversity) Speciation C/N/P to favour soil C sequestration Dissemination of antibiotic resistance Innovative organisations (actors) Multi-functionnality of straw Role of legumes and grassland Regulation of N, P, C flow Protein and N autonomy Livestock contributes to GHG mitigation Perspective : 30 - 40% reduction GHG mitigation options Feeds Genotyping low methane production for selection
Animal health, husbandry and feed quality Energy Manure management Fertilizers Improving C sequestration soils (4 p 1000) Grazing Precision livestock farming Balance between meat and milk production Building Ruminal fermentations Cooperation between FACCE and HDHL is promising to enable a Climate Smart and Sustainable Nutrition Security approach Livestock provides non-provisionning ecosystem services besides provision of food Maintenance of grassland and its services Grassland lifespan and management : C storage, specific and functional biodiversity
Concept of bundles of services Composition of the bundle of services: variation Rural Vitality according to local contexts Comprehensive framework and methods to assess the sustainability of livestock system Synergies and trade off between services (+ and -) Environment Levers that can improve delivery of services Scenario of evolution : farm to food chain and territory Production Heritage Too simplistic evaluation of C and feed vs food competition Summing up LCAs single products in a Linear Model The C footprint of food (kg CO2 eq/kg)

Multi dimensional evaluation of our diets, effect of the proportion of animal product and of the livestock production system Nutritional quality of animal products : Comprehension of the role of nutrients and the matrix effect Improving the roles of livestock and the coupling between livestock and crops Efficient and safe feed chains : cascading approach, maximal use of biomass (food then feed), optimal use of land, alternative feeds/forages, protein self sufficiency Robust and efficient animals and herds: genetic resources, identification of appropriate phenotypes, new breeding techniques and programs Ecological cycles : mitigations of emission, maximisation of C storage, livestock and soil fertility Biorefinery of animal by products, Societal Challenges Livestock Production: ATF vision Resource Efficiency Healthy livestock and People Responsible Livestock Production
Healthy Livestock and people Research gaps Antimicrobial resistance in the concept of one health Mechanism of dissemination: reservoir of resistance, transfer within food chains, Prevention : early detection (PLF), robustness, acquisition and stimulation of immunity, role and installation of microbiota, feeding and husbandry practices, local organisation, Alternatives therapies: use of viruses (phages), vaccines development, Disease prevention and control New diagnostic tools, Prediction of pathologic emergences and risk assessment , conditions of pathogens transmission, Host-pathogen dialog and reciprocal adaptation : pathogen biology, host defences (inflammatory and immune responses) and interaction, mechanism of infection, Animal Welfare Animal based indicators : improved management and traability for consumers
