A Unitron panted product.

Stimulus invented by two Danish pig producers in cooperation with Unitron. Stimulus is a device which can perform a fully automatic, proper and uniform stimulation of sows while inseminated.

Stimulus is performing an automatic stimulation of sows. The stimulation is done in two stages – in 2 programs. The first program which is started when Stimulus is turned on will stimulate the sow roughly with some heavy pressures on the back and in the loin area.

This program lasts 60 seconds – and when it ends, program 2 is activated automatically. 

The other program “soft” stimulates the sow with gentle pressures/pushes in the sow’s groin. It takes only one employee to look after 3 Stimulus – For instance the worker places the first Stimulus on sow no. 1 and activates the stimulating process by pressing the on / off button on Stimulus. After this the employee places Stimulus no. 2 on sow no. 2 and activates it – and places no. 3 on sow no. 3. 

After having mounted the 3 Stimulus the first sow will be ready for the actual insemination where the catheter and semen bottle is put in place – the semen bottle – tube or fat pack – can rest in the special holder which is placed at the end of the “antennas” on Stimulus. 

When sow no. 3 is inseminated the first Stimulus will be ready to “move on” in the row to sow no. 4 etc. 

In this way, 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. 

The electronic is powered by a built-in re-chartable battery which is recharged by a 220V charger that comes along. This can be plugged into Stimulus on the side of the top. The air pressure is added via a spiral rope which is mounted on the top of Stimulus.
