This experiment was conducted to evaluate the effect of dietary garlic powder on performance, blood and egg parameters of Japanese quail, in 8-week old with 3 treatments (diets) and 4 replicates with 20 quail per each replicate for 9 weeks. Treatments including: control (basal diet without garlic powder), treatment 2 (2.5 percent of garlic powder) and treatment 3 (5 percent of garlic powder). Initial and final body weight, feed intake, egg production, eggshell thickness and egg weight were not affected by treatments (p>0.05). Yolk cholesterol, blood triglycerides and Uric acid were affected significantly and was significantly lower in treatment 3 than control diet (p<0.05). HDL in treatment of 3 was significantly higher than the other treatments (p>0.05). The results of this study demonstrated that adding 5% garlic powder to the laying quail diets resulted in improve blood parameters and cholesterol-reducing effect in egg yolk without adverse effects on performance and egg traits.
