Research output: Contribution to journalArticlepeer-review


A physiological computer model of digesta flow (DIGEST) in the GI tract of the growing pig is discussed. Dry matter, as well as liquid flow, is simulated through three compartments of the GI tract (stomach, small intestine and cecum-colon). Absorption of material (solid and liquid) is also simulated by the model. The calibration procedure, sensitivity analysis and validation results are also presented.
