Day-old growing quail chicks were randomly distributed to12 dietary treatments with three replicates of 12 chicks each. A total treatment was made in a 4x3 factorial arrangement, involving 0, 30, 45 and 60% dietary inclusion level of wheat with or without supplementation of two types of multienzyme preparation. A metabolic trial at 3 rd week of age was conducted to determine the nutrient utilization. After 5 wk of age, 2 quails per replicate were sacrificed to assess the carcass traits and organ yield. The results revealed energy metabolizability and nitrogen retention was significantly (P>0.05) poor as the level of wheat increased in the diet. Energy metabolizability was significantly (P< 0.01) improved by the supplementation of either types of enzyme, however, nitrogen retention was not influenced by enzyme supplementation. There was no significant difference in DM and fat metabolizability, as well as retention of calcium and phosphorus among the dietary treatments. The carcass characteristics and organ yields also did not differ among the dietary treatments. It was concluded that wheat can be included up to 60% level in the diet of growing quails and NSP hydrolyzing enzyme supplementation did not prove beneficial.
