Abstract

This study was conducted to evaluate the efficacy of wheat and wheat bran  as the source of phytase in a 5 week broiler feeding trial. One thousand day-old broiler chickens(Ross$^{(R)}$) were divided into 20 pens of 50 broilers(25 male and 25 female) each. Four pens were randomly arranged to one of the five dietary treatments: T1, control diet containing normal nonphytate P(NPP) ;  T2, T1 - 0.1% NPP; T3, T2 + 600IU microbial phytase(NOVO$^{(R)}$) per kg diet; T4, T2 + 600IU plant phytase from wheat and wheat bran; T5, T2 + 600IU plant phytase from wheat and hydrothermally treated wheat bran. Reduction of NPP level by 0.1%(T2) reduced weight gain and feed intake but plant phytase treatments(T4 and T5) recovered the lost performance. Plant phytase treatments showed better (p<0.05) weight gain and intake than the microbial phytase treatment(T3). There was no difference between regular wheat bran treatment(T4) and hydrothermally treated wheat bran treatment(T5). Mortality was the highest by low NPP diet(T2). Availability of ether extract and crude ash of grower diet was the highest(p<0.05) in normal wheat bran diet(T4). Availability of Ca and P of grower diet was the highest(p<0.05) in T4 followed by T3 and T5. Availability of Mg, Fe and Zn was drastically improved by phytase treatments(T3, T4 and T5). Excretion of Ca, P, Mg, Fe and Zn was the lowest(p<0.05) with microbial phytase treatment(T3). Serum level of Ca and Mg was the highest(p<0.05) with the low NPP treatment(T2). Tibial ash content of T2 and T3 was lower(p<0.05) than that of T1, T4 and T5. However, tibial Ca content was higher(p<0.05) in T1 and T2 than other treatments. Tibial P and Mg contents were the highest(p<0.05) in T1. It was concluded that plant phytase from wheat bran can be effectively used to improve P utilization. Hydrothermal treatment of wheat bran prior to inclusion in the diet had no beneficial effects.
