Improving enzyme resistance to pelleting conditions
        
P. Dalibard, Y.G. Liu
 
 

Over the past years, a number of growth and digestibility tests have demonstrated the interest of NSP enzymes in poultry and pig feeds. Enzymes are proteins with specific 3-dimensional structures, which, in common with all proteins, are denatured by heat. This always poses a problem for the incorporation of enzymes into feeds when it comes to industrial application. 

 

Rovabio Excel, produced by Adisseo, is a multi-enzyme product with two main activities, xylanase and beta-glucanase. It has been tested on different animal species and different types of diets. As most of the feed enzymes, it is available in two forms: a dry form with normal resistance to temperature (up to 85 degree Celsius) and included in the feed before pelleting or a liquid form applied by spraying onto the feed after pelleting.

 

However, the liquid application requires a specific investment in the feed mill and a cold logistic as the product must be delivered and stored in cool conditions. This is a limitation for the development of enzyme utilisation, especially in tropical countries.
