            Calf  pen: This  is  the  pen  meant  for  housing  young  calves  separately.  It  can  be
            located either at the end or on the side of the milking barn. This location facilitates
            taking calves to their dams quickly. If there are large numbers of calves, a separate
            unit of calf shed should be arranged and located nearer to the milking barn. The calf
            pen should have an adequate spacing to facilitate cleaning and enabling exercises

            pen will depend on the number of calves to be housed. The front wall should at least
            be constructed about 0.6 m to 0.9 m high solid while the rest of the space can be
            covered with wooden poles or a wire mesh. The calf pen should also be equipped
            with appropriately designed water and feed troughs.
