To let the boar walk in front of the insemination boxes, we place boar doors in the corridor.
These doors can be unlocked manually from the back of the boxes.
It is also possible to make this system work automatically. In this system the time to lock the boar in every section can be set. After this time the next door will be unlocked automatically.
By means of sensors, the exact location of the boar will be monitored. It is possible to let a second boar walk after the first one.
