Copper nanoparticles effectively reduce Salmonella Enteritidis in broiler chicken diet and water.

RESEARCH HIGHLIGHTS: Supplementation with CuNP in feed and water reduced Salmonella Enteritidis count.Supplementation with CuNP did not affect intestinal integrity of broilers.CuNP did not affect weight gain or total lactic acid bacterial counts.The results demonstrate the potential of CuNP as alternative antimicrobials.
