Effects of dry distillers' grain on fecal prevalence and growth of E. coli in batch culture fermentation from cattle

Cattle are main reservoirs for a significant food borne pathogen, E. coli. Asymptomatic colonisation by E. coli in cattle occurs in the lower gastrointestinal tract specifically the mucosal surface of the rectum and the organism is shed in the feces.

 

The fermentation of cereal grains for ethanol production results in a co-product called distillers' grain (DG) which can be used as livestock feed.  Wet distillers' grain (WDG) is the solid fraction that may be used as a feed or dehydrated to produce dried distillers' grain (DDG). In a previous study, the feedlot cattle fed with WDG has a higher prevalence in E. coli.
