All INRAE infrastructures are engaged in quality process and is approved for minimizing environmental impact (ISO 14001). An internal welfare committee works to help people take care of experimental animals. All infrastructures are equipped to measure animal performance (weight, milk production and composition, body condition score) and individual intake. At “Herbipôle”, dairy cows and beef cows can be used in nutritional and physiological experiments. Part of the animals are used in systems experiment designed to study strategies to meet the objectives of producing meat and milk with grass while minimizing inputs. An experimental and training platform (https://youtu.be/eVC4FPi2iGk) is available for quantifying in vivo enteric methane emissions in ruminants. It comprises: 4 chambers for adult cows,  SF6 tracer and breath analysis technique , and 4 automatic head chambers for cows and 1 for calves (GreenFeed®) that include CH4, CO2, H2 and O2 fluxes measurements. To phenotype and monitor cattle behavior in relation to animal welfare and health through PLF devices individual feed intake and feeding behavior can be monitored, The barn of 170 dairy cows is equipped with a Real Time Locating System of animals (CowView, GEA®), cameras, sensor-based devices recording activity (Medria collars). Smart sensors introduced in bolus are also available to monitor rumen pH and temperature (San’Phone, Medria).
