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.
