Abstract :
The present study tried to investigate the effects
of probiotic, Pediococcus acidilactici in
concentrations of 1× 109
, 2× 109
and 3×109
cfu
kg-1 diet on growth and survival rate of oriental
bream fry (Abramis brama orientalis, Berg
1949) in comparison to control diet (devoid of
probiotic) for 60 days. In so doing, 180
specimens of oriental bream with initial weight
of 2.69± 0.22 g were divided randomly into12
fiberglass tanks (capacity 110 l).They were fed
at 3-5 percent body weight daily. A the end of
the trial, growth and survival rates were
measured. The best growth performance was viewed in
treatments rather than the control because of the
improvement of gut microflora balance, which
performed by probiotic P. acidilactici, following
by the enzyme secretion for increasing nutrient
digestibility and fish appetite. The best
bodyweight gain, specific and daily growth
rates, and the lowest feed conversion ratio was
observed in treatment, feeding with diet
containing 2× 109
cfu kg-1 diet (P < 0.05). The
results of the current study revealed that it is the
role of probiotic, P. acidilactici to the diet of
oriental breamfry and A. brama orientalis,
which resulted in growth performance increase
and feed efficiency ratio improvement.
