چکیده انگلیسی
This study was conducted to evaluate dietary myo-inositol (MI) requirement of juvenile parrot fish. A basal experimental diet was formulated and used as a control and four other diets were prepared by supplementing 100, 200, 400 or 800 mg MI per kgâ 1 diet (designated as M0, M100, M200, M400 and M800, respectively). Triplicate groups of fish (initial body weight, 11.5 ± 0.01 g) were fed one of the diets to apparent satiation twice daily for 18 weeks. The results showed the significant increase of growth performance at dietary MI level of 100 mg kgâ 1 but no further improvement was observed at higher MI levels. Significantly lower feed conversion ratio was obtained in fish fed the M200 and M400 diets than those fed M0 diet. Significantly lower AST and ALT activities were recorded in fish fed 100 and 100-800 mg kgâ 1 MI, respectively, compared to those fed the control. Whole-body protein content decreased significantly at all supplementation levels of MI in comparison to control. Liver MI concentration significantly increased by MI supplementation and inversely correlated with liver lipid content. Broken-line regression analysis indicated that MI requirement of parrot fish is 94.3 and 121.3 mg kgâ 1 diet based on weight gain and liver MI concentration, respectively. The findings suggest that approximately 100 mg kgâ 1 MI can support maximum growth of juvenile parrot fish and prevent a potential abnormal lipid metabolism.
