Herding a cow into a small pen then restraining it to help deliver the calf and/or aid in nursing can be difficult and dangerous, requiring quick movement and strength. A Calving/Maternity Pen, consisting of steel-tubed panels, automatic head-gate, sweep-gate, and rear-access door, is designed to solve this problem. The sweep-gate has a lower level that can be opened to give the new-born access to nurse, and the rear-access door is designed to provide safer entry to assist with delivery, if necessary.
