Stimulus is making insemenation of sows easier. An automatic stimulation of sows will save you a ton of man hours, and avoid fatigued employers. The insemination may be carried out by just one employee – and thus save valuable time other places in the production. The moves that Stimulus performs to press and stimulate the sow is made by air pressure and an air pressure pump is mounted on the top of Stimulus. Built-in electronic controls the air pressure in the pump.
