This study investigated the effects of feeding garlic-supplemented diet on performance and egg quality in laying Japanese quail. A basal diet was supplemented with garlic at level of 4% to make diet. The garlic-free diet was used as control treatment. The diet were fed to 44 day-old laying japanese quail. The quials were distributed to one treatment group of 72 quail each replicated four (18 quials per replicate) in a completely randomized design. The results showed However, performance of the quails were not significantly affected, but for body weight was significant (P<0.05). Also the garli powder at the weight live at slaughtering and liver weight (P=0.05) increased. The results of this study revealed that garlic powder has detrimental effect on breaking strength(kg) and Egg Haugh unit of the quails (P<0.05).Therefore, concluded that dietary containing of garlic powder in the rations may be used for economical of laying quails.
