Abstract :
A feeding trial was conducted for sixty continuous
days to determine the effect of dietary Aloe vera
and Echinacea on immunological parameters of
shirbot (Barbus grypus). Four hundred and twenty
fish weighing 50-60 g were randomly subjected
to seven different treatment, including one control
(Aloe vera and Echinacea free diet), A1 (0.1% of
Aloe vera), A2 (0.2% of Aloe vera), A3 (0.5% of
Aloe vera), E1 (0.1% of Echinacea), E2 (0.2% of
Echinacea), E3 (0.5% of Echinacea) each in triplicate.
Some immunological parameters such as
respiratory burst activity, Complement activity,
Lysozyme activity, serum bactericidal activity, total
protein and albumin were assessed. At the end
of treatment, 30 fish from each group were challenged
with Aeromonas hydrophila. No significant
difference was seen in respiratory burst activity of
Aloe vera and Echinacea treatments compared to
the control group (P > 0.05).Complement and serum
bactericidal activity enhanced in all the Aloe vera
groups (P < 0.05). Total protein and globulin in Aloe
vera and Echinacea treatments decreased compared
with control group (P > 0.05). Lysozyme activity in
0.2% Aloe vera treatments was significantly higher
than Echinace and control groups (P < 0.05). According
to obtained results, it might be concluded that
the feeding of this species by Aloe vera (specifically
0.2%) extract could likely enhance immunological
parameters better than Echinacea
