| The environmental impact of 12 dairy farms in Denmark, Germany and Italy was evaluated using an LCA approach and the most important parameters influencing their environmental sustainability were identified. The farms represent different production methods (organic vs. conventional), summer feeding systems (confinement vs. pasture) and annual production levels (6275–10,964 kg ECM cow−1). There was large variability in stocking rates (1.1–11.0 LU ha−1) among farms, which has a major impact on the production per unit area of farmland, on feed self-sufficiency and on farm surplus of nitrogen. The proportion of grassland on farmland used for forage production or pasture varied from 0 to 100%. The lowest global warming potential (GWP), acidification,... |
