Effect of supplementation multi-enzyme on productive performance of two strains of Japanese quail

Abstract

Five levels of multi-enzyme (Roxazyme) 0, 0.010, 0.020, 0.030 and 0.040% from total ration, and two strains of grower Japanese quail (Coturnix coturnix japonica ), desert and white color strain, and the interaction, use in this study. 640 birds of quail of two strains distributed to 5 experimental treatments, in each one 64 birds, and then divided to 4 replicates, with 16 birds in it. The results assert significant differences (p≤ 0.05) for strain, multi-enzyme addition and the interaction between them on body weight, weight gain, feed conversion coefficient, water conversion coefficient, carcass weight, dressing percentage, edible giblets percentage, breast percentage, Globulin on blood serum. The results of interaction between strain and multi-enzyme addition also show significant events (p≤ 0.05) on feed intake and water intake. Finally, Desert quail strain recorded the best net revenue (Iraqi Dinar/Kg live weight) (Iraqi Dinar/Kg carcass), the treatment of multi-enzyme addition 0.030% (T4) as well as registered heist net revenue (Iraqi Dinar/Kg live weight) (Iraqi Dinar/Kg carcass) and interaction between these treatments also show up best net revenue (Iraqi Dinar/Kg live weight) (Iraqi Dinar/Kg carcass). No significant effect in all other traits in this paper.
