INRA (www.inra.fr) is an internationally recognized and the Europe’s top agricultural research institution. The institute carries out mission-oriented researches for better food and nutrition, preservation of the environment and competitive, sustainable agricultural practices. INRA lends its expertise to public decision-making and to shaping national and international research strategies. It mobilizes a broad spectrum of cognitive research, from biology and fundamental ecology to applications in agriculture, nutrition and the environment. It draws on the diversity and excellence of its research community to offer breakthrough innovations that improve living standards and sustainability in our societies, to push back the boundaries of knowledge, and to unlock the complexities of food systems in space and time. In the current project, the Joint INRA-CIRAD-Montpellier SupAgro SELMET (Livestock Systems in Mediterranean and Tropics) provide its expertise. SELMET oversees developing projects for adapting Mediterranean and tropical farming systems to the current economic, environmental and social challenges of that regions. Several actions are currently focusing on studying physiological and genetic components determining the intraflock variability on feed efficiency and individual robustness on a spectrum of conditions whereas the design of new farming practices is fostered by mobilizing precision livestock techniques for autoweighing (Walk-over-weighing), heat detection and social networks studies in sheep.
