Effects of Multiple Enzyme (ROVABIO[R] Max) Containing Carbohydrolases and Phytase on Growth Performance and Intestinal Viscosity in Broiler Chicks Fed Corn-Wheat-Soybean Meal Based Diets (Report‪)‬

INTRODUCTION Although feeds that contain high non-starch polysaccharides (NSP) are relatively inexpensive, these products are often not used in broiler feed due to their poor utilization of nutrients and low feed efficiency. It is well known that supplemental enzymes such as [beta]-glucanase, xylanase, protease and amylase break these polymeric chains into smaller pieces, thereby improving their nutritional value (Cowieson and Ravindran, 2008). Additionally, Lazaro et al. (2004) suggested that supplementation of feed with p-glucanase and xylanase improved the average daily gain and feed conversion. They also reported that these enzymes reduced digesta viscosity, which leads to improved contact between endogenous enzymes and nutrients, thereby improving digestibility.
