Original XPC's Impact on Salmonella Typhimurium

07 February 2014

US - Commercial broilers challenged with Salmonella typhimurium show reduced load and prevalence of the bacterium, along with improved feed conversion, reports Jonathan Broomhead, PhD, manager of global poultry research and technical support with Diamond V.

Colorado Quality Research recently tested effects of Original XPC™ in broilers challenged with Salmonella typhimurium at seven days of age.

Birds fed XPC had a numerically reduced prevalence and statistically reduced load of S. typhimurium at 14 days of age. By 35 days of age, the Salmonella prevalence and load was low but XPC-fed birds showed continued reduction in Salmonella load.

The researchers also found that feed conversion was statistically improved in XPC-fed birds through 14 and 35 days of age.

Diamond V offers an extensive portfolio of research on a range of Salmonella serotypes in poultry with published reports on Original XPC effects shown through in-vitro testing, in-vivo challenges, controlled pen studies and paired house field trials. Research covers commercial broilers and turkeys, caged layers and breeding stock.

Details of Diamond V’s research on Original XPC fed to broilers are available on-line.
