Over the last decade, interest in the use of commercial enzyme preparations in corn-soybean diets has increased dramatically. Still, other than phytase, there are only a handful of commercial and experimental enzyme preparations available for use in corn-soybean diets. Such preparations normally contain one or more of the following enzyme activities: β-mannanase, α-galactosidase, α-amylase, xylanase and β-glucanase, and most recently, proteases. Most of the research reported so far indicates that supplementing corn-SBM diets with these enzymes results in increased body weight and improvement in feed efficiency accompanied in some instances with a reduction of gut viscosity and a shift to a more favourable gut environment for the growth of beneficial bacteria. Less is known about the change in nutrient digestibility and utilisation of corn-soy diets upon the use of these commercial enzymes, which requires further investigation.
