A New Phytase with Reliable Matrix Values
The phosphorus (P) matrix values of a phytase provide the nutritionist with information about how much inorganic P can be replaced by a phytase in the feed. To provide reliable matrix values, multiple trials need to be conducted. This can be assessed either by regular digestibility trials or by bone ash trials. In such trials, the amount of P released from the substrate phytate is determined as a result of adding phytase to the diet at different doses.
