초록 A System dynamics model of pig growth and associated farm level economic impact is developed to evaluate the economic feasibility of three nutritional approaches (phase feeding, avoiding over-formulation, and more accurate estimate of nutrient requirements) to reduce nutrient excretion. The strategies are evaluated in terms of point elasticity of nutrient excretion with respect to profit. Model simulations suggest that more accurate nutrient requirement estimations may be a more profitable strategy than the other strategies evaluated to reduce nutrient excretion from swine producing facilities.
