Effects of garlic and black cumin powder on performance, egg quality and blood parameters of laying quails

The purpose of the present study was to evaluate the effects of garlic and black seed powder on performance, egg quality and blood parameters of laying quails. For this purpose, a total of 160 quails at the age of 11 weeks in a completely randomized design were assigned in 10 cages and were fed with three treatments control, Basal diet supplemented with 3% of garlic powder and Basal diet supplemented with 2% of black seed powder that were used for 1 month. The results showed that feeding quails with 3% of garlic powder and 2% of black seed powder had no significant effects on the egg production, egg quality parameters (egg weight, yolk relative weight and albumen relative weight), body weight, fertility and plasma parameters from 11 to 14 weeks of age in comparison with control group (P>0.05). But during 11 weeks of age, the diet containing 3% garlic powder significantly reduced feed intake when compared with control group (P
