This research was conducted to evaluate the partial replacement of plant sources by
date waste meal (DWM) on growth, hematological and resistance of common carp. A
total of 168 common carp fingerling (2.44±0.02 g) were randomly assigned to four
groups in triplicate and fed for 12 weeks with substitution of plant sources by 5%,
10% and 15% of DWM and control diet. Some growth and feed utilization parameters
including WG, SGR, CF, PER and LER were improved in group fed with 10% DWM; but,
there were no significant differences (P>0.05) in growth and feeding parameters
between different groups. The results showed that replacement of plant sources by
DWM in diets did not affect MCV, MCH and all biochemical parameters while the fish
treated with 15% WDM exhibited significantly decrease in RBC, Hb and neutrophil
compare to the control and other groups (P<0.05). In addition, there were no
significant differences (P>0.05) of Hct, MCV, MCH and all biochemical parameters
between treatment groups. Resistance rate to acidy and thermal-salinity stress
increased significantly in 5% DWM and control group (P<0.05), respectively. The
present study indicates that DWM may be included up to 10% as a substitute for
plant sources in common carp diet.
