The use of grazing pastures in goat production: development of an approach to combine optimized use of the forage resource and the control of related risks

摘要: This article describes an approach to provide support for changes in herd management increase the proportion of grazed forage diet dairy goats. research was conducted collaboration with researchers, agricultural advisors and farmers. The use introduces many sources uncertainty farmers (fluctuating resource, risks drought or parasite infestations). It is thus difficult propose a robust technical model that reliable variety circumstances. aim described here make progressive adaptation feasible. based on formalisation farmer’s practices time space, makes it possible analyse combinations different resources relation indoor feeding, production epidemiology gastrointestinal nematodes, used as infections. These representations help diagnose system, identify possibilities discuss corrective actions. In supporting guiding such innovative processes, researchers have modify angle from which they observe situation. tool initially developed data acquired Mediterranean conditions. However, could be interest other systems and/or regions, particular who currently intensive lost know-how required managing grazing herd, but are concerned by return less order fulfil criteria sustainable development.
