Research conducted by a team from the College of Agriculture at North Dakota State University investigated the effect of Direct Fed Microbial (DFM) products on the control of E. coli in feedlot cattle.
Results of the trial showed a significant reduction (32%) in fecal shedding
of E. coli O157:H7 among the steers treated with the Lactobacillus Acidophilus
BT1386. Steers placed on the DFM supplement were almost three times less likely
to shed E. coli in their feces as opposed to their control counterparts.
In addition, feeding the DFM significantly reduced the probability of
new infections with Salmonella among DFM-treated cattle, compared to controls.
This work was published in the March 2008 issue (with an erratum in the May 2008
issue) of the Journal of Food Protection.
The DFM strain used for the
study is the same commercial product available as Micro°©-Cell LA and Micro-Cell
GOLD from Lallemand Animal Nutrition, North America. Lallemand offers a range of
DFMs for the beef feedlot industry: Micro-Cell GOLD for cattle on a diet of
dried distiller grains solubles (DDGS), Micro-Cell LA for pathogen control and
Micro-Cell PB for hot rations.
