摘要:
Feeding corn dried distillers' grain with solubles (DDGS) has been linked to increased fecal shedding of Escherichia coli O157:H7 in cattle. A study was conducted to compare the impact of three diets containing (dry matter basis) 40% corn DDGS, 40% wheat DDGS, or 20% corn and 20% wheat mixed DDGS to a standard barley grain finishing diet on fecal shedding in cattle challenged with a 10(10) CFU mixture of four nalidixic acid resistant E. coli O157:117 strains. Rectal grab samples (n = 544) were collected over 70 days and screened for E. coli O157:117 by direct plating and immunomagnetic bead separation. Feeding diets containing DDGS had no effect (P > 0.05) on the intensity or duration of fecal shedding of E. coli O157:H7 compared with the standard barley grain finishing diet.
