In Switzerland, a lot of dairy farms combine indoor feeding with partial grazing. To develop a scientifi cally sound basis for the development of practical recommen-dations and optimisations for farms that practice partial grazing and indoor feeding of fresh grass from 2014 to 2016, a comparison of three different grassland-based milk production systems was conducted. Partial grazing with indoor feeding of fresh grass with reduced (EGKF; 430 kg/cow and year) and increased (EGKFplus; 1.160 kg/cow and year) concentrate supplementation was com-pared with the full grazing system with seasonal calving and reduced concentrate supplementation (VW; 90 kg/cow and year). The system comparison was implemented on the experimental farm (EF) of the Vocational Edu-cation and Training Centre for Nature and Nutrition in Hohenrain, complemented by investigations on 36 pilot farms (PFs) which are located in the central lowland and which are practicing one of the systems.The average grass yield in the EF from 2014 to 2016 was 117 dt DM/ha and year. The energy and protein content of the herbage from the semi-continuous pastures of the VW herd remained at a constantly high level throughout the vegetation period (6.6 MJ NEL/kg DM, 246 g CP/kg DM), whereas that of fresh grass for indoor feeding showed considerable variations in nutrient content in the EF and pilot farms. In the PFs, the average milk production over the three-year period was 7,218, 8,457 and 6,268 kg ECM/cow and year in EGKF, EGKFplus and VW, respectively. In terms of energy effi ciency, cows on EGKFplus farms were more effi cient than those in the two other systems. The labour input of the feeding accor-ding to the working hour per cow and year was higher for the EGKF (22.0 h) and EGKFplus (18.5 h) systems than for the full grazing farms (7.6 h). Compared with the reference dairy farms, the PF farms had, on average, a higher income per working hour (€19.1/h vs. €23.4/h) and a higher agricultural income per year and hectare (€1,699 vs. €2,192). The highest income was registered for VW farms. The highest nitrogen effi ciency was found in EGKF farms (53.4%), followed by EGKFplus (45.7%) and VW (44.2%). An appropriate cow breed, optimal grazing management, high-quality swards, ef-fi cient work processes and an adequate workload were identifi ed as the most important factors affecting the success of the systems through farmers’ participation in exchange groups.
