This project will generate a powerful set of results to improve robustness of the dairy cow selection and to give to dairy farmers new tools for future dairy farming. It fits with the fifth of the major societal challenges of ANR and the first research theme of the Apis-Gene company; on FE and limitation of N pollution and methane emission by ruminants to improve the overall efficiency of ruminants.

- The main expected result will be a new, durable, strategy to improve FE of dairy cows without impairing robustness of cows. This strategy will combine new methods and indicators to assess FE on a large scale in order to develop a selection program on this factor. It will indicate the best periods,
duration, and indicators that can be used to assess FE of dairy cows.
- New phenotyping tools will become available for both research and farmers at the end of the project. New tools using the new phenotyping devices and models will become available to help farmers in monitoring livestock management, including possible precision feeding.
- New models simulating interactions between functions and explaining robustness capacities of the cows will become available to simulate consequences on life function priorities, and robustness, across the animal’s productive lifespan.
- New algorithms for genomic selection on body mobilization profiles will be developed allowing genetic selection to reduce the intensive use of body reserves generally observed in early lactation. Better body condition score, improved reproduction performances and less metabolic diseases are expected from this selection. This is a further element of the goal of increasing dairy cow’s robustness.
