Carbohydrases improve performance of broilers fed both nutritionally adequate and downspec wheat diets

Abstract

Although the main non-starch polysaccharides (NSPs) in wheat are arabinoxylans, considerable amounts of β-glucan and cellulose are also present. In soybean meal (SBM) and canola meal, the major polysaccharides are pectins and cellulose. Since more plant ingredients containing different forms of NSPs are being used for diet formulations, an enzyme combination with additional activities each differing in substrate preference may further enhance nutrient utilization. A study was conducted to investigate the use of Rovabio Excel LC (liquid), an enzyme complex containing 19 carbohydrase activities on broilers fed a nutritionally adequate or downspec diet.
