Chances and challengesfarmers (Ipema et al, 1998) and therefore the introduction of an AM-systemon a farm will effect the farm and farm management in several ways. Tillnow little economical information is available from commercial herds usingan AM-system. Several simulation models have been developed to calculatethe economical effect.One of the basic models used, is the Room for Investment model(Mandersloot, Arendzen). This model computes the amount of money thatcan be invested in an AM-system, without any change of the net returncompared with the conventional milking system. The RFI-value iscalculated by accumulating the annual returns from increase in milk yield,annual savings in labour costs, annual savings in not investing in theconventional milking parlour and then dividing this total by the annualcosts of the AM-system. The model is able to use the farm specific factorsand circumstances to calculate the RFI-value. In figure 2 the results of acombined sensitivity analysis are presented. The figure shows clearly thatincrease in milk yield and labour savings are essential factors regardingthe economy of AM-systems. The RFI-value for the basic farm with 10%milk yield increase, 10% labour saving, medium automated milking parlourand 25% annual costs of the AM-system amounts to Euro 134 000. Thedifferences between the extremes are rather large, almost equal to theinvestment of a single stall AM-system.ReferencesArendzen I, A.T.J van Scheppingen, 2000, Economical sensitivityof four main parameters defining the room for investement of AM-systemson dairy farms, in: Robotic Milking, Proceedings of the internationalsymposium held in Lelystad, pp. 201-211.Devir S., C.C.
