Feed for free-roaming gestating sows

A feeding solution for gestating sows in group with controlled access and feeding.

Asserva, with the Selffeeder, provides an alternative and innovative solution to manage the gestating sows feeding in group. Unlike ESF stations, the Selffeeder reduces waiting times, lowers stress and makes the sows easier to manage, static batch by static batch. With a lower cost and an easier mechanical system, the Selffeeder concept has 3 to 4 times more feeders than an ESF station.

The sow that is allowed to access to feeding enters one of the feeders and is directly isolated from the rest of the animals by an automatic back gate. A RFID antenna recognizes the animal electronic chip and distribute the feed, according to the feeding plan. The next measure will follow as soon as the level sensors will detect that the trough is empty, and so on, until the complete ingestion of the daily allowance. Distribution is adapted for each sow without any feed stolen or wasted.

  • Wheeled feed dispenser & "Vita Dose"
    The wheeled feed dispenser runs on compressed air. There is no motor so very little maintenance. It is precise to 5g. The "VITA DOSE" feed dispenser comes with its own container and can dispense supplements for single sows (20g doses).
  • Feeding control
    The trough is ftted with TIT system (trough inspection technology). It dispenses the next dose of feed only if the previous dose has been eaten: no waste, clean troughs and less frequent cleaning required.
  • Better management with high-performance data base
    The system centralises all data from the central workstation, and shares information about the herd. Communication with the system is fast, straightforward, and comprehensive. It can be ftted with radio unit or smartphone.
