Simulating rotational grazing management.
Dairy systems predominantly based on rotational grazing are notoriously hard to manage. In order to ensure profitability, this type of production requires quite good organisation, planning, and operating capability on the part of the farmer. A simulation-based decision support system, called SEPATOU, has been developed for this purpose. At the core of the decision support approach lies an expli...
متن کاملCharacterizing and Simulating a Rotational Grazing Strategy
The management of dairy production systems based on rotational grazing and maize-concentrate feeding requires a complex lookahead decision making procedure to elaborate a seasonal strategy that is sufficiently robust to uncertainty. In this paper, the problem is characterized rather precisely as finding for the late winter to early summer period an appropriate combination of commitments concern...
متن کاملSimulating management strategies: the rotational grazing example
This paper argues in favour of a simulation approach relying on an explicit and rigorous modelling of the management strategy that underlies the farmer s decision-making behaviour. A strategy is defined as a roadmap of intended technical tasks over a management period. It is tied to an overall objective and specifies what to do depending on the situations encountered. An essential feature is it...

متن کاملSward Factors Influence on Pasture Dry Matter Intake of Grazing Dairy Cows: A Review
Successful pasture-based milk production systems pivot on balancing dairy cows’ feed requirements with seasonal and annual fluctuations in pasture production. In order to maximise cow production from grazing dairy systems, it is necessary to reach an efficient utilization of grazed grass for feeding cows and the development of appropriate grazing management systems designed to maximize daily pa...
