ABSTRACT
Talazadeh F, Houshmandi K., Effect
of barley malt extract on intestinal Escherichia coli
counts in Ross broilers, Onl J Vet Res., 24 (5):307-311, 2020. We report effect of
0.2-0.5% barley malt extract in daily drinking water of day old Ross broilers
for 45 days on Eschericchia coli counts (CFU g-1) in digesta of distal small intestine and whole caeca. Controls
were not given malt. Escherichia
coli in digesta of 10 cm anterior to the junction with caecum and rectum
and whole caeca were used for microbial assay estimated as CFU g-1. Results
suggest that 2% malt barley extract reduced (P < 0.05) E coli counts ~14 to 16% compared with controls in the ceacum of broilers.
These reductions were repeated incubated
on Mac Conkey, Nutrient and and eosin methylene blue agars.
Keywords: malt extract, Escherichia coli, intestine, bacterial population,
broiler chickens.
