Popis:	The interaction between chick type and xylanase supplementation (Avizyme 1300) of a wheat based diet was investigated using a 3×2 factorial arrangement. The diet (645g wheat/kg) was supplemented with 0 or 1g/kg xylanase and fed to broilers, broiler breeders, or pullets from 1 to 19 day-old. The basal diet was formulated based on the average of the nutrient requirements of all bird types investigated. Body weight, feed intake, feed: gain ratio, upper intestinal digesta content viscosity, and relative weights of gastrointestinal organs to body weight were determined. There were significant effects of chick type on live weight, daily gain, feed intake, and feed: gain ratio (P 0.05). Small intestinal digesta content viscosity was not different between different chick classes (P>0.05), but enzyme inclusion significantly (P
