A substrate-based approach to enzyme selection and prediction of associated matrix values in broiler diets

IT WILL BE DEFINITELY HELPFUL TO POULTRY INDUSTRY BECAUSE FOR THREE YEARS THE RAW MATERIAL PRICES ARE VERY MUCH VOLATILE AND IF WE CAN CONCLUDE SOMEWHERE NEAR THE MATRIX VALUES,ECONOMICALLY IT WILL BE VERY BENEFICIAL.

One of the most challenging problem in the enzyme industry nowadays is that how to quantify the feed substrate for enzyme use? Most matrix values of a commercial enzyme are used in a generalized manner wherein it reflects all the matrices both on the substrate and non-substrate ingredient. To achieve full efficiency and feed cost benefits, feed enzyme companies should device ways on how to accurately target the substrates within a certain formulation beyond what there matrix values can give.

Absolutely correct. one of the way for NSP degrading enzymes is that an accurate and fast determination of reductions in in vitro viscosities of the household cereal grains in the feed mill. Degree of reduced viscosity would definitely provide a decision what enzymes at which level to be included in the compound feed. Novel enzymes have now a strong formulation to achieve this as compared to to old fashioned enzymes.

A substrate based approach to enzyme use is a good idea. But its pre-requisite would be to quantify the targeted substrate in the prospective feed formula. This may increase the complexities in the whole process - but it would increase the accuracy and one would be able to quantify the enzyme response as well.
