Nachhaltigkeit von drei graslandbasierten Milchproduktionssystemen in der Schweiz mit der Bewertungsmethode RISE

Dairy farming is a key sector for Swiss agriculture and the food industry. Therefore, sustainability of dairy farms is important. Grassland-based farming systems are the most common production system, combining the indoor feeding of fresh grass with partial grazing. The effects of three dairy production systems (VW: full grazing plus on avg. 46±93 SD kg concentrate (KF), GFKF: indoor feeding/partial grazing plus on avg. 345±204 SD kg KF and GFKFplus: indoor feeding/partial grazing plus on avg. 1007±353 SD kg KF) on sustainability, according to RISE, were studied on 12 pilot farms in the lowland of Switzerland. In most of the sustainability themes, the farms performed medium to good according to the RISE evaluation scale. The GFKFplus farms produced the highest output of milk by low N- and P-self-sufficiency, showed the highest energy input and the lowest greenhouse gas output per kg milk. The GFKF group achieved remarkable results by moderate N-, P- and energy inputs. The VW farms showed a lower milk output but a higher level of feed self-sufficiency and a lower energy consumption. In the search for the optimal production strategy, farms should consider the individual farm structure (contiguous areas), the market potential but also social aspects such as the preferences of the farmer`s family
