The benefits of bee pollen are common knowledge - it contains 13 vitamins, 14 minerals and 15 amino acids and studies have found horses consuming bee pollen improved performance. This new study proves it also has antimicrobial properties on the gastrointestinal flora, which is vital news in light of ever-increasing antibiotic resistant bacteria ...
The Effects
of Bee Pollen Extracts on the Broiler Chicken's Gastrointestinal Microflora
Res VetSci, 2013 Aug; Vol 95(1):34-7
The aim of
this study was to investigate the effects of bee pollen ethanolic extracts on
the in vivo gastrointestinal tract microflora colonization of broiler chickens.
A
completely randomized experiment based on six treatments (different
concentrations of bee pollen - 0, 5, 15, 25, 35 and 45gkg(-1) diet) was used
during 7weeks. The highest count of faecal Enterococci was found in the
experimental group with the addition of 15g of pollen (8.85±0.87log CFUg(-1))
per 1kg of feed mixture. The highest count of Lactobacilli was detected in the
experimental group with 35g of pollen per 1kg of feed mixture and the highest
number of the Enterobacteriaceae genera count was found in the control group
(8.43±0.15log CFUg(-1)).
Moreover,
the MALDI TOF MS Biotyper identified the following genera: Escherichia coli,
Proteus mirabilis, Klebsiella oxytoca, as well as Lactobacillus acidophilus, L.
crispatus, L. fermentum and L. salivarius from the Lactobacilli group and
Enterococcus avium, E. casseliflavus, E. cecorum, E. faecalis, E. faecium, E.
gallinarum, E. hirae and E. malodoratus from the Enterococci group. Additionally,
the in vitro antimicrobial activities of pollen against five bacteria species
isolated from gastrointestinal tracts of chickens were tested.
The best
antimicrobial effect of the pollen extract was detected against K. oxytoca.
