Real-world experience with longer lying areas in elevated stalls has been very positive
When a free stall is set up and controlled properly (horizontal distance between neck rail and brisket board at least 25–30 cm), cows position themselves better when lying down and lie straighter and visibly more relaxed due to a greater amount of free space at the front. The general recommendation for the horizontal distance between the neck rail and the manure edge is 160–170 cm. To achieve this sufficient distance between the manure edge, the neck rail and the brisket board, free stall flooring measuring more than 1.9 m in length are needed. In combination with longer lying mats, this all adds up to the perfect solution.
This not only increases lying comfort, but also noticeably improves the cleanliness of cows and elevated stalls. The tails lie predominantly in the stall and the risk of hairless areas on the hock joints is reduced.
