A total of 360 one-day old Japanese quails were used in a 3×3 factorial arrangement with completely randomized design consisting of 9 treatments and 4 replicates of 10 birds in each. The utilization of rosemary and peppermint essences in the diet had no significant effect on feed intake, body weight gain and feed conversion ratio in entire experimental period (P>0.05). Furthermore, the interaction of rosemary and peppermint essemces was not significant on performance parameters (P>0.05). The utilization of rosemary and peppermint essences alone or together did not have any significant effect on blood parameters including malondihylehyde and uric acid concentrations, total antioxidant capacity and also the activity of blood enzymes of Japanese quails at 35 day of age (P>0.05). In addition, the effect of rosemary and peppermint essences was not significant on breast meat color parameters including lightness (L), redness (a) and yellowness (b) (P>0.05). Generally, according to the results of this study, it seems that the consumption of rosemary and peppermint essences had no significant effect on performance, blood enzymes activity, blood peroxidant and antioxidant as well as breast meat color parameters of Japanese quails.}, keywords = {Blood enzymes,Japanese quails,rosemary,meat color,peppermint}, title_fa = {اثرات اسانس گیاهان رزماری و نعناع فلفلی بر عملکرد، وضعیت آنتی‌اکسیدانی و فعالیت برخی آنزیم‌های خون بلدرچین‌های ژاپنی}, abstract_fa = {این پژوهش با هدف بررسی اثرات سطوح مختلف اسانس رزماری (صفر،100 و200 میلی‌گرم در کیلوگرم) و اسانس نعناع فلفلی (صفر،100 و200 میلی‌گرم در کیلوگرم) بر عملکرد، وضعیت آنتی‌اکسیدانی و فعالیت برخی آنزیم های خون بلدرچین‌های ژاپنی انجام شد. تعداد 360 قطعه بلدرچین ژاپنی یک‌روزه در قالب یک آزمایش فاکتوریل 3×3 بر پایه طرح کاملاً تصادفی با 9 تیمار، 4 تکرار و 10پرنده در هر تکرار مورد استفاده قرار گرفتند. کاربرد اسانس‌های رزماری و نعناع فلفلی در جیره بر مصرف خوراک، افزایش وزن بدن و ضریب تبدیل خوراک در کل دوره آزمایش تأثیر معنی‌داری نداشت (05/0
