The main function of cow bed is to let each cow "sleep in place", do not interfere with each other, and reduce the cow standing on the bed and emitting manure. The independent and clean bed standardizes the resting position of the cows and increases the sleep quality and milk production of the cows. The bedridden steel pipe adopts the internal and external hot-dip galvanizing process, and the plating penetrates into the pipe body. The cold bending adopts one-time molding, and the connection is connected by holding screws, so that the whole does not need to be welded to reduce burr defects and reduce the damage to cows. The size is flexible and can be customized according to the size of the cow, and the size can also be adjusted to suit the cow by holding the card.
