Coefficients of ADMD and APD of the test ingredients are presented in Table 5. ADMD varied widely among the four fish meals (44% to 76%). SM and FSPC were high (95% and 102%). Among crustacean meals, RCM had the lowest value (51%) and SHM had the highest (84%). Coefficients of APD varied from 63% to 99%. FMB and FMD (71% and 70%) were significantly different from FMA (85%) and FMC (63%). Similar APD values were found in FSPC (99%), SHM (98%), and SM
(95%). APD for RCM and FMC were 85% and 63%, respectively.
