摘要：The aim of this study was to evaluate the feasibility of using X-xylanase in the diet to improve tilapia growth. Fourexperimental diets containing X-xylanase (Hostazym®, Huvepharma, Antwerp, Belgium) at levels of 0 (control),1050, 1500, and 1950 endopentosanase units (EPU) were used in this study. The growth performance trial wascarried out for 56 days. At the end of the study, there were no significant differences between the groups fed bycontrol and the experimental diets in terms of survival rate, condition factor and weight gain. However, the highestweight gain was recorded in fish fed a diet containing 1500 EPU of X-xylanase. Fish fed diets containing 1500and 1950 EPU X-xylanase for 56 days had significant better feed efficiency compared to those of fish fed thecommercial diet and other experimental diets. It was therefore concluded that the addition of X-xylanase to thetilapia diet was able to improve the feed utilization and consequently enhance fish growth.
