Feed barrier

A feed barrier, comprising:

• a plurality of vertical, planar frames arranged side-by-side in a row along a trough of a barn, each frame defining an L-shaped internal space with a ground and an adjacent frame or end post, the L-shaped internal space being subdivided into an upper portion and a lower portion, a width of the lower portion being greater than a width of the upper portion;
• a plurality of flaps, each flap connected to an associated frame, disposed in the lower portion of the L-shaped internal space thereof, and movable by pivoting and sliding relative to the associated frame for closing off or not closing off at least a part of the lower portion of said space;
• and
• mechanical blocking means for changing the feed barrier between an access position in which each flap can at least pivot towards a front and a rear of the associated frame about a generally horizontal axis, and a blocked position, in which said pivoting is blocked at least to the rear of the associated frame, and vice versa;
• wherein each frame comprises:
• a first vertical upright configured to be fixed to the ground at a lower end thereof,
• an upper crosspiece extending generally perpendicularly to said first upright from an upper end of said first upright,
• a second vertical upright extending towards the ground from said upper crosspiece, the second vertical upright having a height substantially equal to half a height of said first upright, and
• a middle crosspiece extending from a lower end of said second upright, and extending generally perpendicularly to said first upright in a direction away from said first upright;
• and wherein each flap is disposed below said middle crosspiece of the associated frame.
