The exogenous xylanase is widely assumed to have the ability to degrade plant cell and release nutrients from endosperm and aleuronic layer cells. The beneficial effects of xylanase in increasing energy density for diet are documented beyond doubt; the responses obtained are variable and sometimes lacking. Therefore the study was to investigate the effects of dietary electrolyte balance (dEB) value in fully plant origin low energy level diets supplemented with exogenous xylanase on the growth performance of broiler under high ambient temperatures. 800 Arbor Acres broiler were randomly allocated to 4 feeding treatments of five replicates. There were 40 birds kept in a 3.8 M2 floor feeding pen of which ambient temperature was between 32~28 ℃. In 1-3 weeks feeds containing 23% CP, 4-5 weeks with 21% CP, two stages energy level are the same as 3100 Kcal/kg feed. Treatment 1: control group, Treatment 2: dietary xylanase (16,000 U/kg feed) and water electrolyte (calculated 50 meq/L, water:feed ratio=2 L/kg), Treatment 3: dietary exogenous xylanase, Treatment 4: dietary xylanase (16,000 U/kg feed) and electrolyte (calculated 325 meq/kg feed). The results showed that the 5th week body weight (P = 0.0404) and overall body weight gain (P = 0.0307) were significantly increased between treatments. By using exogenous xylanase to increase dietary energy level or increase dEB value could improve growth performance, it also has the results of addition and multiplication of these two methods.
