3.4. Effect of fish-meal replacement on apparent dry matter, protein and P
digestibility coefficients
In general, ADC of dry matter varied from 58.99% to 68.09%, ADC of
protein ranged from 76.55% to 82.53% (Table 7), but treatments did
not affect digestibility. ADC of Fe increased with the increasing fishmeal
levels (P b 0.05). There were no differences in ADC of Ca, P, Zn,
Cu and Mg among all the treatments (P N 0.05).
