Reusing chicken litter shows benefits.

. All these broilers -- chickens raised for meat -- need millions of tons of litter, or bedding material. Reusing chicken litter can save costs.

There exists some health and safety concerns though. A new study shows that the environment in reused poultry litter can deter growth of pathogens like Salmonella.

"When you read or hear that broiler litter is reused to raise multiple flocks of chickens, the typical reaction is that it must be bad for food safety," says Adelumola Oladeinde, a co-author of the recent study.

"Our study demonstrates the exact opposite." Oladeinde is a researcher at the USDA's National Poultry Research Center in Athens. He and his colleagues found that 'good' bacteria in used poultry litter can hinder Salmonella growth"It may be worthwhile to invest time and resources to characterize the bacteria in reused litter," says Oladeinde.


 "We can develop the promising ones into beneficial microbes for better chicken gut. Chicken litter plays a big role in determining broiler health. After a broiler chick gets to a farm, it usually spends the next several weeks pecking and living on litter.In fact, chicks begin to eat litter even before eating from feeding troughs or drinking.



The microbiome present in the litter likely become the 'first settlers' in the guts of the chicks. "These first microbes play a key role in determining gut health," says Oladeinde. "Therefore, it is critical to determine what a beneficial litter microbiome looks like."
