Environmentally friendly
LiptoCitro is a prebi-
otic, immunoestimulant and
growth promoter with a
proved antibacterial activity. It can be
used at any stage of the fish produc-
tion cycle and no withdrawal period
is needed because it does not containany antibiotics. It is used at dosage
rates of 2.5Kg/M/tonne and it can be
incorporated in the feed mill during
diet manufacture, or top-dressed on the
feed using oil or molasses at the farm.
It is made of a combination of prebiotics,
plant extracts and plant essences and does
not develop off-flavours in either fish or
crustaceans. LiptoCitro is capable of improv-
ing nutrient digestibility, favouring beneficial
intestinal flora, eliminating pathogenic bacteria,
and promoting the immune system, resulting
in higher resistance to stress and disease and
improved growth, survival, FCR, production
and cost-efficiency, even in the event of bacte-
rial, viral and some parasitic disease outbreaks.
LiptoCitro trial dataTrials have been conducted in laborato-
ries, research centres and farms
with a range of fish and shrimp
species and pathogens.
Trials conducted in the
Veterinary Sanitary Vigilance
Centre (VISAVET) of theComplutense University of
Madrid, Spain showed that
LiptoCitro possessed strong in
vitro antibacterial activity against
a range of pathogenic bacterial
species commonly encountered in
aquaculture production systems
(Table 1).
Trials carried from May to
November in a commer-
cial farm in Spain showed the
efficacy of Liptocitro to con-
trol Haemorrhagic Enteritis
outbreaks in rainbow trout
(Oncorhynchus mykiss). A total
amount of 1,700 MT of commer-
cial feed with LiptoCitro added
at 2.5Kg/MT was
used. All the fish had
the same handling
and usual European
vaccine prophylaxis.
In the control lots,
which were not fed
Liptocitro, several
Enteritis outbreaks
occurred over the
six month trial peri-
od and the fish had
to be treated with
antibiotics. However,
the lots of infected fish that were fed
with LiptoCitro improved significantly,

recovered and did not need any antibiotic
treatment at any stage of the trials.
Trials conducted throughout a production
cycle on rainbow trout (Oncorhynchus mykiss),
under commercial conditions and using con-
trol lots, showed 14 percent improvement in
FCR in the fish that were fed with 2.5 Kg/MT
of LiptoCitro. This digestibility improvement
was evaluated in further trials using the same
inclusion rates of Liptocitro in the feed. The
results showed that the cost of the ration
could be reduced without altering FCR. This
was achieved by decreasing the amount of
expensive animal origin protein in the diet andincreasing the inclusion of cheaper vegetable
protein instead.
Six month trials were conducted in four
replicate tanks in the laboratories of the
Agricultural Development and Food Research
Institute IMIDA, in Murcia, Spain. These
trials were carried on European sea bass
(Dicentrarchus labrax) under ideal conditions
and without a disease challenge. The fish
fed three g/kg of Liptocitro showed three
percent improvement in growth and survival
rates and eight percent improvement in FCR
over the fish in the control tanks (statisti-
cally significant at 95 percent confidence level)
(Table 2). Improvements in the haemocrit and
haemoglobin levels of fish blood following a
stress test were also observed.
These trials have shown how a better
intestinal integrity, even under ideal conditions
of low density and very low mortality, results
in better nutrient assimilation thus improving
the feed conversion rate. Therefore, in the
field, a better nutrient
assimilation as a result
of a good intestinal
integrity will have
even more advanta-
geous effects than
those observed under
ideal conditions with
regards the improve-
ment of the growth
and survival rates.
LiptoCitro anti-
bacterial efficiency,
survival and FCR
improvement and
growth and immune
system promoter
effect have also
been tested in vari-
ous shrimp species
and under different
farming and envi-
ronmental condi-tions. These results
can be provided
upon request.
Trials carried
out with LiptoCitro
have shown that the
use of prebiotics
and phytobiotics in
fish and shrimp feed
leads into better
production param-
eters and enables
sustainable aquacul-
ture production on
a long term basis
by reducing the use
of antibiotics and
decreasing fish meal
content in diets.
