parison to the controlled group. The
number of beneficial microorganisms
which protect against pathogens has
increased. The effect of this probiotic
bacteria in lactic fermentation can lead
to the improvement of general condition
and health of broiler chickens.
There were no significant differences
in the number of heterotrophic intestine
bacteria between the experimental and
controlled group. This can be caused by
the higher number of lactic acid bacteria,
not the pathogens. No pathogenic
bacteria such as: Samonella sp., Shigella
sp., E. coli beta haemolytic and Clostridium
perfringens reducing sulphate were
observed (in both examined cut of the
digestive contents of the small intestine).
There was an insignificant number
of microscopic fungi (yeast and hyphal
fungi) at the low level (below10 2 ⋅jtk⋅g –1 )
(in the digestive contents of the small
intestine from the experimental group).
This can be a result of high number of
such bacteria as Lactobacillus sp. in this
group. This bacteria acidifies its environment
by producing lactic acid, and
the low reaction (pH) is responsible for
the fungi increase. Furthermore, that
the antagonistic lactic bacterial strain in
comparison to fungi seemed to be inefficient
for lactic bacteria fermentation
and (LAB) the general condition and
health condition of broiler chicken can
be improved. L-carnitine has detoxifying
features due to the chelates ability. However,
the chelations ability is common
almost in every organic acid, nevertheless
only few kinds of such substances
can be considered as an exemplary. The
exemplary chelates substances with the
optimum biding ability are as follows:
ascorbic acid and L-carnitine. L-carnitine
facilitates the absorption and transport
of bioelements and keep them in the
body store, returning them to metabolism
when needed, removes potentially
destructive surplus of bioelements and
eliminate toxic elements (Ambroziak,
2000).
The Figure 2 shows the results of
coli/lacto calculated on the basis of the
proportion of the Enterobacteriaceace to
Lactobacillaceae number. Aminikarnifarm
did not have a significant effect
on lowing coli/lacto coefficient in the
small intestine. However, above mentioned,
coli/lacto was low (below 1) in
the experimental and controlled group,
which shows proper and positive composition
of intestine micro flora. In the
Gajewska’s research (2009) a positive
effect of plant preparations on the intestine
micro flora of broiler chicken can be
seen. When used with the Digestarom
preparation coli/lacto was 0.14. Some
authors claimed that the results where
poultry farmers use herb preparations,
are comparable to antibiotic growth
stimulators used in the past such as: avilamycine
(Jamroz, Kamel, 2004; Lee at
al., 2004).
