| Abstract | ||||
| A total of 600one dayold Japanese quail chicks were used in this experiment to study the effect of using different levels of okara meal in quail diets growth performance, nutrients digestibility and economical efficiency as well as to reduce environmental pollution. Birds were distributed randomly and divided equally into 8 experimental groups with 3 replicates of 25 birds each. Okara meal was used as a substitution of soybean meal at levels of 0, 20, 40 and 60 %. Each either without or with prozyme supplementation at 0.5 kg/ ton. Therefore, the dietary treatments were distributed in a 4 X 2 factorial arrangement. All treatments containing okara meal were compared with control group, which was formulated without okara meal and enzyme supplementation. Birds were housed in battery cages under the same management conditions up to 7 weeks of age. Results obtained indicated significant (P<0.05) improvement in the average values of CP and EE digestibility due to using okara meal at level of 20 % of soybean meal. While, adding prozyme to quail chick diets significantly (P<0.05) improved all nutrients digestibility. Data showed that the use of 20 % okara meal instead of soybean meal significantly (P<0.05) increased the average values of live body weight and weight gain. Also, supplemental prozyme to different levels of okara meal diets increased both live body weight and weight gain, decreased feed intake and improved feed conversion values. While, feeding quail chicks on diets containing graded levels of okara meal as replacing for soybean meal without enzyme supplementation increased feed intake values and recorded the worst feed conversion values compared to control group. Data showed that replacing okara meal for soybean meal at levels of 20, 40 or 60 %, with or without supplemental enzyme, decreased the total cost/kg live body weight and increased economical efficiency values compared to control group. Therefore, it could be concluded that Japanese quail chicks could be fed diets containing different levels of okara meal up to 60 % as replacing for soybean meal either without or with supplemental enzyme without adverse effect on quail chick performance, nutrient digestibility and economical efficiency. | ||||
