Bac­te­ria link to lame broil­ers

The Poultry Bulletin - - NORTHERN VIEWS -

Arkansas Univeristy re­searchers have iden­ti­fied a species of bac­te­ria never be­fore as­so­ci­ated with lameness in broiler chick­ens, bring­ing sci­en­tists closer to find­ing a way to pre­vent in­fec­tions.

Us­ing ge­netic tools and chick­ens raised on wire floor­ing, the re­search team de­ter­mined the bac­terium Sta­phy­lo­coc­cus ag­netis is sig­nif­i­cantly in­volved with a con­di­tion lead­ing to lameness in broiler chick­ens.

Dou­glas Rhoads, Univer­sity Pro­fes­sor of bi­o­log­i­cal sci­ences and di­rec­tor of the Cell and Molec­u­lar Bi­ol­ogy in­ter­dis­ci­pli­nary grad­u­ate pro­gram at the uni­ver­soity, said 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,” Rhoads said. "This is the first re­port of this poorly de­scribed pathogen in chick­ens."

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.¡
