A feeding device for preventing displacement of feed during livestock feeding inside a livestock trailer is described. The device includes a wall bracket configured for connection of the device to an interior surface of the trailer and a net frame having a net connected thereto. The net frame is connected to the wall bracket and pivotable from an elevated open position permitting the feed to be placed on a substantially flat manger surface of the trailer to a substantially horizontal closed position where the net covers the feed on the manger surface and permits the livestock feeding to occur through the net while the net prevents the displacement of the feed.
