In pig equipment, sow bed is a very important equipment. The quality of sow bed is related to the safety and health of piglets and sows. For example, if the quality of sow floor is not up to the standard, the sows are prone to collapse in it, which may even break the legs of the sows, bring certain economic losses to the pig farm, even affect the future of the pig farm Development. So when we buy pig equipment, we have to choose the quality of sow bed.
1. First of all, there is the floor problem. The weight of a sow is very considerable, which requires the quality of the floor to be very good. If it is because of the floor problem that affects the safety of the sow, it is a bit of a loss.
2、 It is better for sows to bear the bed with a higher weight limit, because a larger bearing limit means that the quality of the bed is better, that is to say, the quality of the bed legs and crossbeams of sows is up to the standard.
3. In general, the sow bed is made of metal. Most of the metal is steel pipe and steel plate. Generally, the thickness of steel pipe is 2.0mm. Some sow beds are even thickened, so friends are advised not to buy steel pipes with thickness less than 2.0mm.
