Enzymes: how to come to the most cost-effective inclusion in your formulation?

摘要

Enzymes have become a key solution in resource efficiency. Using enzymes as an additive enables other ingredients to release more nutritional value to the animal. They reduce feed costs, save the environment and enable a maximum use of local ingredients.Enzymes are expensive. How much enzyme should we use in the recipe to have the maximum effect at the lowest cost?Using enzymes in linear optimization is complex because the behaviour of enzymes is different from traditional feed ingredients. The phytase effectiveness is not linear. It is degrading with higher inclusion rates. NSP enzymes are only used at certain pre-defined inclusion rates. The effect of enzymes is diminishing when they are used in combination with other enzymes.
