Higher value of NSP enzymes with an eye on high raw material costs

摘要

A study based on optimisation of "broiler grower"formula proves the economic benefits of NSP enzymes, regardless of raw material prices or nutritional levels required.NSP (non-starch polysaccharides) enzymes are known to increase the digestibility of raw materials for monogastric animal species, such as rapeseed meals and DDGS, offering an alternative to soya bean meals when prices are surging and thus allowing to offset higher feedstuff costs. A study led by Adisseo shows that the economic interest of the versatile enzyme is greater when raw materials are more expensive, whatever the country and the availability oflocal ingredients are. The study is based on the monthly optimisation of a "broiler grower" formula which nutritional constraints and the raw materials offered are specific to the five countries surveyed: South Africa, Poland, Turkey, Tunisia and France(Table 1). Starting from monthly prices of raw materials, the formulas have been optimised both with and without NSP enzymes (Rovabio), in order tomeasure the consequences on the formulation and to calculate the return on investment.
