Characterizing and Simulating a Rotational Grazing Strategy
نویسندگان
چکیده
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 concerning the fields allocated to grazing, those kept just in case of need, the time profile of maizeconcentrate distribution, the nitrogen fertilization policy and the field rotation policy. A simulation tool designed to evaluate tentative man-made strategies under given climate scenarios is described.

Simulating 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 کاملSimulating detection of cattle-fever tick (Boophilus spp.) infestations in rotational grazing systems
To evaluate the relative influence of ecological and management factors on the probability of detecting cattle-fever tick (Boophilus microplus and Boophilus annulatus) infestations in rotational grazing systems, we adapted a simulation model of Teel et al. [J. Range Manage. 51 (1998) 501] that examines interactions among Boophilus ticks, cattle, and habitat type under rotational grazing systems...
متن کاملSimulating 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 کاملSynthesis Paper Rotational Grazing on Rangelands: Reconciliation of Perception and Experimental Evidence
In spite of overwhelming experimental evidence to the contrary, rotational grazing continues to be promoted and implemented as the only viable grazing strategy. The goals of this synthesis are to 1) reevaluate the complexity, underlying assumptions, and ecological processes of grazed ecosystems, 2) summarize plant and animal production responses to rotational and continuous grazing, 3) characte...
متن کاملSoil Organic Carbon Content and Stocks in Relation to Grazing Management in Semi-Arid Grasslands of Kenya
Rangelands cover approximately 85% of Kenya’s land mass and is a major resource for livestock farming with a considerable potential to mitigate climate change, yet these lands are stressed differently by various management. Our study aimed at determining the influence of grazing management systems (rotational, continuous and ungrazed) on soil organic carbon stocks in Yoani ranch located in the ...
