Research has shown no statistical difference in the prevalence of Escherichia coli O157:H7 or salmonella between cattle fed steam-flaked corn and those supplemented with dry distillers grain. The current study was funded by the Kansas Beef Council and conducted at
Previous research suggested that feeding DDGs increased E. coli O157:H7 shedding in fecal matter. "Unlike our previous studies, we found no evidence to indicate that dietary inclusion of DDGs or corn processing methods have a significant effect on the prevalence of E. coli O157:H7 or salmonella in cattle feces," said Kansas State University professor of microbiology T.G. Nagaraja.
Nagaraja's previous research implicated DDG feeding in the prevalence of E. coli O157:H7 conflicted with research conducted at the University of Nebraska-Lincoln. To view the full research report, click HERE.
