The Effect of Dietary Supplementation with Propolis on Bacteria Colonization Pattern in Gastrointestinal Tract of Broiler Chickens
Abstract
|
Recent studies have suggested an increase in the production performance
in poultry fed diets with propolis1,2. This
advantages could be related to effect of propolis on gastrointestinal
microbiota which increase the levels of beneficial bacteria and decrease the
pathogenic types3. The aim of this study was to determine the
total bacterial count, the count of Lactobacillus genera and the count
of Enterobacteriaceae
genera in ileum and crop of broiler chickens. This experimental study was
conducted on 120 Ross 308 broiler chickens of equally distributed sex, which
were randomly divided into three groups: control group (C) and two
experimental groups of chickens (P1 and P2). Throughout the whole study (for
42 days) the control group of chickens was fed feed mixture while feed mixture
that was fed to the experimental groups of chickens contained propolis in
amount of 0,5 g/kg (P1 group) and 1,0 g/kg of feed mixture (P2 group). The
study revealed statistically significant difference in number of Lactobacillus
genera in ileum (p=0.036) between control and experimental groups of
broiler chickens while there were no statistically significant differences in
total bacterial count (p=0.351) and in number of Enterobacteriaceae genera (p=0.990). The study
further showed statistically significant difference in number of Enterobacteriaceae
genera (p=0.043) in crop between control and experimental groups of broiler
chickens while there were no statistically significant differences in total
bacterial count (p=0.066) and in number of Lactobacillus genera
(p=0.558). One can conclude that dietary supplementation with propolis
influence the colonization patterns of gastrointestinal tract of broiler
chickens. |
