The enclosure (1) has two side walls (3) and a front wall (5) intended to form the enclosure, where the front wall includes a gate (7). A bar (11) is attached by an attachment point at each of the side walls, so as to maintain a constant distance between the attachment points. The bar is placed remote from the end wall and towards the inside of the enclosure, so as not to impede a calf or a person when moving the gate. The bar is placed at the ground level, so as to avoid discomfort to the movement of the calf or the person within the enclosure.
