Hops extract may reduce Clostridium
in chickens Source of Article: http://members.ift.org/IFT/Pubs/Newsletters/weekly/nl_110508.htm November 5, 2008 A new study from the U.S. Department of Agriculture’s Agricultural
Research Service shows that hops contain substances that control pathogenic
bacteria in the intestines of chickens. The hop plant (Humulus lupulus) contains bitter acids known to be potent
antimicrobials, including lupulone, which is
believed to control levels of the disease-causing agent Clostridium perfringens in chickens. Researchers examined the
effect of feeding different concentrations of lupulone
to broiler chickens to determine the compound’s impact on Clostridium
populations in the intestinal tracts of birds inoculated with C. perfringens. After 22 days—the timeframe associated with clostridial
disease in broiler chickens—C. perfringens
counts were significantly reduced in the lupulone-treated
group compared to another group of chickens that did not receive the lupulone treatment. The reductions ranged from 30 to 50
percent. Agricultural
