Pro's and cons on the use of different formulation techniques for feed additives Enzymes and fat addition Make your own poultry feed through MakeFeed Make your own dairy feed through MakeFeed

There are conflicting opinions regarding the application of enzymes at the fat coater. Should enzymes be applied to the feed before the fat, and then be exposed to the high fat temperature and risk of enzyme inactivation, or should they be applied post-fat application. With the concern then focusing on the enzyme’s ability to penetrate the fat coating on the pellets? Assay work carried out with samples from the commercial feed mills have shown there to be no clear interaction between enzyme stability and recovery, pre- or post-fat application, of the enzyme at the fat coater. Research cited by Engelen (1998) also supports this view. The recovery of Xylanase LC was shown to be unchanged irrespective of the fat temperature, the fat level and the spraying order.
