First step of a model of calcium and phosphorus metabolism in growing pigs: Fate of ingested phosphorus in the stomach

Phosphorus (P) digestibility represents complex digestive and metabolic phenomena which are embodied in a unique coefficient. A dynamic mathematical model, based on mechanistic concepts is developed to improve pig feed formulation systems. In this first step, it simulates the fate of different forms...

description Phosphorus (P) digestibility represents complex digestive and metabolic phenomena which are embodied in a unique coefficient. A dynamic mathematical model, based on mechanistic concepts is developed to improve pig feed formulation systems. In this first step, it simulates the fate of different forms of dietary P in the stomach. The model also accounts for dietary calcium (Ca) content, gastric transit time and pH. It simulates consistently the inorganic P released at the exit end of the stomach . However, this model has to be challenged by external data.
