Modified dry sow arcs aim for targeted feeding

I’ve been working with an outdoor producer to set up a new trial to target delivery of feed into modified dry sow arcs, with the help of a BPEX Innovation Fund grant.

The producer started thinking about how he could feed his pigs effectively by reducing wastage, without incurring too much cost. Because the land can be quite wet at times it was having an impact on sow condition and was also leading to increased aggression. Extra food was having to be given to compensate for what was being lost in the wet ground.

So he has developed a concept where he can simply pull up to his dry sow arc and activate a quick release lever and deliver food into each hut.

On my first look at a group of sows being fed in the new huts, what struck me was just how calm the sows were. A little food is blown in to start with, then the rest is delivered between the two huts. The sows seem to find a natural order. There has also been a significant reduction in bird activity in the dry sow paddocks.
  • The following data will be collected from both the trial feed delivery system and current dry sow feeding system:
  • Group size (20-22/pen)
  • Feed usage per sow
  • Straw usage
  • Bird prevalence in respective paddocks
  • Staff time in feeding and bedding up
  • Sow aggression as measured by incidents of vulva biting         
  • Sow physical performance data
