The objective of the study was to evaluate the response of laying hens in long producing cycles to a multicarbohydrase-phytase enzyme complex. Compared to a reference positive control diet, two negative control diets with –5 or –7% AME or dAA and – 0.18 percentage point of avP and Ca were supplemented with the enzyme complex.
This enzyme solution was able to fully compensate the down-specification of the diets as shown by the digestibility measured at 36, 56 and 84 weeks of age.
