Poultry trough feeding system having its conveying element and/or inner trough segment walls at least partly provided with an abrasive surface structure.
A poultry trough feeding system comprises a feeding track having at least one longitudinal trough segment 5 with inner walls 9 which together delimit a feeding space which at its upper side is accessible for poultry via a feeding opening 10. A feed supply is provided for supplying feed at an inlet position into the feeding track, and a drivable conveying element 30 which extends along the feeding track for transporting feed from the inlet position along the feeding space, such that poultry is able to pick feed out of the feeding space. The conveying element 30 and/or the inner walls 9 of the trough segment 5 are at least partly provided with an abrasive surface structure 20 for having beaks of the poultry abraded and worn as they pick feed out of the feeding space of the trough segment 5.
