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

, : First step of a model of calcium and phosphorus metabolism in growing pigs: Fate of ingested phosphorus in the stomach. Livestock science15 109(1-3): 63-65

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.

In this study we tested the hypothesis that peptone in the intestine stimulates the secretion of the CCK-releasing peptide (CCK-RP) which mediates CCK secretion, and examined the enteric neural circuitry responsible for CCK-RP secretion. We used a...
