Finding correct inclusion levels of phytase in broiler diets

摘要

Calcium and Phosphorus levels are important ingredients in broiler diets. Yet these should be available at correct levels, which can be enhanced by phytase. Applying the correct ratio of this enzyme is essential, however. A ratio of Calcium (Ca) to Available Phosphorus (AvlP) must be attained in broiler diets if bone development and performance are to be normal. The phytase enzyme is added to most diets as a standard inclusion, and its addition changes the consideration of how we should add Ca and AvlP. Nutritionists can take their own precautions when formulating diets to ensure that they use phytase correctly and that the Ca and AvlP inclusions are within acceptable levels. This is particularly true when higher than normal doses of phytase are used.
