Increasing global demand for vegetable and animal proteins for human consumption is a real challenge for cattle production. In France, the levels of dry matter, protein and energy feed self-sufficiency vary from a dairy farming system to another but remain rather a high level (88%, 77% and 87%, respectively). These high levels of self-sufficiency are permitted by an important link to the ground. However, areas for improvement remain possible like using more grass available, using local protein resources (by-products) and incorporating legumes in crop rotations. © 2014 B. Rouillé et al.
