AGRIBUSINESS: LAMENESS IN BROILERS LINKED TO BACTERIA.

Researchers at the University of Arkansas have identified a species of bacteria that had never before been associated with lameness in broiler chickens, bringing scientists closer to finding a way to prevent infections. Douglas Rhoads, University Professor of biological sciences and director of the Cell and Molecular Biology interdisciplinary ,used genetic tools and chicken raised on wire flooring to identify staphylococcus agnetis linked to causing lameness in broilers.The bacteria had been associated with inflammation of the mammary gland in cattle but not in the legs of broiler chickens. Lameness causes the chickens to suffer and the diseased birds are not fit for human consumption. Rough estimates are that lameness in the Arkansas poultry industry could cost growers about $20 million a year due the loss of birds.Lameness in broiler chickens is a significant animal welfare and financial issue. Bob Wideman, professor of poultry science at the U of A, had shown that growing young broilers on wire flooring is a contributing factor to lameness in broiler chickens. This study, which included Wideman, shows that S. agnetis is also a contributing factor for lameness in those chickens, Rhoads said. Bio security measures such as cleaning, washing with disinfectants and spraying plays a vital role to prevent diseases.Housing,feeding and medication also are factors to consider in the poultry value chain to ensure disease free stock. pic and portions of story courtesy of world poultry.
