Effects of Dietary Prebiotic Mito (Mhf-Y) and Starvation on the Compensatory Growth, Survival, and Hematological Parameters in Common Carp (Cyprinus Carpio L, 1758)

In order to study the effect of prebiotic mito on compensatory growth following one week starvation in common carp, the fish (4.5 ± 0.05 g) were examined for 60 days in three treatments. a control fed with non-prebiotic diet with no starvation (t1), a 2^nd group starved for one week then fed 0.2% of prebiotic (t2) and 3^rd group received no prebiotic diet after one week starvation. the highest percent of weight gain and specific growth rate and condition factor were obtained in the control followed by t2 with significant differences (p<0.05). the lowest amount of food conversion ratio and the highest amount of protein efficiency ratio were recorded in t1, too. the mortality rate was zero in all treatments. the number of red blood cells showed insignificant differences between the control and the other groups (p> 0.05). hemoglobin and hematocrit values significantly differed between t1 and two other treatments. t2 contained the highest number of white blood cells and lymphocyte while the percent of basophil, eosinophil and monocyte did not differ between treatments significantly (p> 0.05). so, although the use of 0.2% prebiotic largely caused compensatory growth in carp but was not so sufficient that exceed those of the control group. however, the addition of prebiotic mito significantly elevated hematological status of the fish.
