A feeding railing for animals comprising a frame, a plurality of vertical spikes fastened to said frame and adapted to extend pairwise behind the animal's head on both sides of the neck and being spaced apart by a distance which is larger than the width of the neck and smaller than the width of the withers of the animal and comprising at least one wheel supporting the frame so as to be movable along the ground, comprising a frame which has connected with it a floor plate extending rearwardly over a given distance near the ground. Driving means comprising buffer means for the wheel for storing energy during the rotation of the or each wheel in one direction and by releasable guard means for blocking the rotation in the other direction can be provided.

Movable fence for pasturage control comprises a plurality of contiguous fence sections with transverse displacement means contacting the ground, means connecting contiguous sections, means forming an opening in each section to permit passage of the head of an animal therethrough and pushing means for allowing fence displacement.

An animal feeder device, particularly suitable for use as an aid in the feeding of cattle, which incorporates a means for rearranging the feed when necessary in order to permit the animals to feed easily. The feeder comprises a frame assembly, a track disposed along the top of the frame and an auger assembly movable along the track. The auger of the auger assembly projects forwardly of the frame and is adapted to disengage feed from a feed pile situated in front of the frame, the disengaged feed falling within convenient feeding range of the animals.

A feeding pen for haystacks that minimizes the amount of hay which is not consumed by cattle or other animals. The feeding pen consists of four sides, three of which are rigidly attached together while the fourth side is movable with respect to the others. As the animals consume the hay on the movable side of the pen, they push inwardly on the movable side to gain access to more hay. Additionally, animals on the other sides may move the rigid portion which is positioned upon skids.

Device for feeding animals comprising at least one feeding fence with a frame displaceable over a ground surface, a number of bars attached to the frame which in pairs define openings through which the animals can place their head, and means for displacing the feeding fence over the ground surface. The frame supports through support means directly on the ground surface and is provided with a floor plate extending at a small interval above the ground rearward of the frame to a rear edge making contact with the ground, which plate can support at least the front legs of the animals which have pushed their head through the respective openings, wherein the feeding fence is of the self-catching type having close to each opening a swivel bar locking behind the head of the animal after the head has been pushed through the opening, and wherein the displacing means comprise motor drive means which prevent movement of the feeding fence in the non-active state.
