POULTRY FEEDING SYSTEM HAVING WALLS WHICH DELIMIT OR EXTEND THROUGH A FEEDING SPACE AT LEAST PARTLY PROVIDED WITH SHARP-EDGED LINE-ELEVATIONS

摘要

A poultry feeding system includes walls which together delimit a feeding space which at its upper side is accessible for poultry via a feeding opening. A feed supply is provided for supplying feed at an inlet position into the feeding space, such that poultry is able to pick feed out of the feeding space. The walls are at least partly provided with an abrasive surface structure that includes a pattern of a plurality of sharp-edged line-elevations for having beaks of the poultry abraded and worn as they pick feed out of the feeding space.
