Computerbased Aids To Nutritional Management

The nutrition of the grazing sheep clearly involves complex interactions among the dynamics of ruminant digestion, the pasture ecosystem, and the processes of diet selection and pasture/supplement intake. One useful approach to understanding these interactions has been to build simulation models of grazing systems, and to incorporate these models into computer-based packages to help decision making. In general, this approach involves the mathematical representation of the processes of diet selection, intake, digestion, and nutrient absorption, in relation to tabulated nutrient requirements for different forms of production. A number of decision support tools are now commercially available for use by sheep producers or their advisers.[4]
