Pigs on Probiotics

Probiotics may help fight antimicrobial resistance.

Piglets fed probiotic Enterococcus faecium showed reduced numbers of potentially pathogenic Escherichia coli strains in their intestines, according to a team of German researchers. The research is important, because in 2006 the European Union prohibited the feeding of antibiotics to livestock as growth promoters. Therefore, the research team sought to investigate whether probiotics could substitute for antibiotics, by reducing pathogen populations in the intestines, says Carmen Bednorz of Freie Universitat Berlin, Germany. The study was published in the journal Applied and Environmental Microbiology. Antimicrobials are thought to promote growth in industrially grown livestock because without them, the rationale goes, in such close quarters, a surfeit of pathogens would slow growth. “Our data suggest that the feeding of probiotics could substitute for antimicrobials as growth promoters,” says Bednorz. “This could help to reduce the burden of antimicrobial resistance.
