 Quality pellets
 make a difference
 Do the animals get all the costly feed
 ingredients you have carefully chosen
 for them - or is some of your pelleted
 feed lost as fines during production,
 storage or transport?

 Improve your pellet quality and pelleting
 efficiency with our high performance pellet
 binders and lubricating aids, suitable for
 all feeds!

 aids and other feed additives, visit our
