Abstract

The standard Ca/aP ratio (2.2) can be recommended for application in practical diets. Based on the results of this experiment, no proof was found for our hypothesis that the development of the skeleton in fast growing broilers could not keep pace with the gain of the soft tissues. This experiment showed that the P requirement was not fulfilled with the low aP level in the diet. For determination of the optimal dietary aP level, however, a dose – response experiment should be performed.
