New findings on poultry probiotic research

Must read

TUCKER, Ga. — U.S. Poultry & Egg Association and the USPOULTRY Foundation announce the completion of a funded research project at the USDA Agricultural Research Services and University of Georgia in Athens, Ga., that resulted in new findings on poultry probiotic research.

Researchers included Dr. Nelson Cox and Dr. Brian Oakley of the Poultry Microbiological Safety Research Unit, USDA Agricultural Research Services in Athens, Ga.; and Dr. Samuel Aggrey and Dr. Stephen Collett of the Poultry Diagnostic Research Center at the University of Georgia in Athens.

The researchers looked at how intestinal microbes from a line of broilers selected for high feed efficiency and microbes from a line of broilers selected for low feed efficiency were used to inoculate newly hatched broiler chicks.

Although the origin of the intestinal microbes was not a significant factor, they found that chicks inoculated at hatch with the intestinal microbes had significantly higher growth rates and feed efficiency than those that were not inoculated. These microbes will be further characterized for use as probiotics.

The project was part of the association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A complete report, along with information on other association research, can be obtained at USPOULTRY’s website,
