These hurdles are designed with a recess on the rear part to get over a trough. A lambing hurdle with drinker passage can be integrated in a row of pens, ideally every 2 hurdles. These lambing hurdles are made of galvanised tubes 0 25 mm. Their conception combines lightness and robustness. They can be interlocked thanks to 3-hole plates. Ideal to build lambing pens rows very quickly. They can be equipped with the double suspended hay rack for the feeding between two pens.
