Swiss dairy farms must increasingly cope with climate protection, environ-mental conservation and the use of limited resources.In the context of the Hohenrain comparison of dairy production systems, a comprehensive assessment of the environmental impacts was conducted using the Swiss Agricultural Life Cycle Assessment method. The environmental strengths and weak-nesses of seasonal full-pasture and indoor feeding systems were com-pared.The indoor herd performed signifi-cantly better than the pasture herd in three of thirteen impact categories. In contrast, the pasture herd performed better in seven of thirteen impact categories. A considerable weakness in the pasture herd was its higher methane emissions per kilogram of energy-corrected milk and the one-and-a-half times greater land require-ment per kilogram of energy-corrected milk. The indoor herd had its main weaknesses in deforestation, the phosphorous and potassium resource requirements and higher ecotoxicity. The main causes for poor performance in these categories were maize and soybean meal.
