There are steps you can take to reduce the risk of damaging feed on-farm. If 5% of feed is damaged and lost to dust and waste it can cost up to £5000/year on a 500 sow unit; this could increase to £20000 plus if finishers are included, equating to an extra cost of 1 p/kg deadweight. BPEX has produced a simple guide which you can use to walk your system and look at ways of reducing the risk of waste.
