Values are expressed as mean (n=3, replicate tanks/treatment); in the same columns, values indicated with the same superscript are not significantly different (P > 0.05)

Table 4: Growth and feed utilization indices of Australian catfish fed with CM diets with various nutrient supplements, CM30, CM30F1, CM30F2, and CM30F3 supplemented with phytase at 0, 1000, 2000 and 3000 FTU/kg, respectively; CM45: no nutrient supplement; CMF: only phytase 1000 FTU/kg; CMFA: phytase and crystal lysine & methionine; CMPA: AAs and inorganic P; CMAA: only lysine and methionine, CMP: inorganic P only. (Conducted at 24oC for 84 days under 12:12 light regime). IW = initial weight, FW = final weight, WG = weight gain.
