چکیده
به‌منظور بررسی تأثیر برخی افزودنی‏های خوراکی در مقایسه با پادزیست (آنتی‏بیوتیک) محرک رشد فلاوومایسین، آزمایشی در قالب طرح کامل تصادفی با سه تیمار، پنج تکرار و بیست قطعه مرغ در هر تکرار با استفاده از 300 قطعه مرغ تخم‏گذار لگهورن سفید، سویه های-لاین W-36 انجام شد. تیمارهای آزمایشی شامل شاهد، پادزیست محرک رشد فلاوومایسین به میزان 05/0 درصد جیره و ترکیب افزودنی خوراکی شامل عصاره‏های گیاهی آویشن و پونۀ کوهی، اسید پروپیونیک و مکمل روی به میزان 1/0 درصد جیره بود که در سه دورۀ متوالی دو هفته‏ای درمجموع به مدت 42 روز برای تغذیه در اختیار مرغ‏های تخم‏گذار قرار داده شدند. نتایج این بررسی نشان دادند، استفاده از ترکیب افزودنی خوراکی سبب بهبود معنی‏داری در ضریب تبدیل خوراک، درصد تولید تخم‏مرغ و عیار پادتن (تیتر آنتی‌بادی) علیه آنفلوانزا و لیپوپروتئین با چگالی پایین در سرم خون نسبت به گروه شاهد شد (05/0≥P). مقادیر شاخص‏های پاداکسندگی (آنتی‏اکسیدانی) سرم خون شامل غلظت سلنیوم، ویتامین E، سوپراکسید دیسموتاز و گلوتاتیون پراکسیداز در مرغ­های تغذیه‌شده با جیرۀ حاوی ترکیب افزودنی خوراکی نسبت به دو گروه تیماری دیگر به‌صورت معنی‏داری افزایش یافت (05/0≥P). تیمارهای آزمایشی تأثیر معنی‏داری بر صفات کیفی تخم‏مرغ و فراسنجه‏های بیوشیمیایی خون به غیر از لیپوپروتئین با چگالی پایین نداشتند (05/0≤P). بنابر نتایج این آزمایش به نظر می­رسد که افزودنی خوراکی مورد بررسی می­تواند به‌عنوان جایگزین پادزیست محرک رشد در جیرۀ غذایی مرغ‏های تخم‏گذار استفاده شود.

چکیده [English]
This research was conducted to evaluate the effect of some feed additives compare to Flavomycin growth promoter antibiotic. Experiment was conducted in completely randomized design manner consisting 3 treatments, 5 replicates and 20 hens per each replicate using 300 White Leghorn, Hy-Line W-36 strain. The experimental treatments included: control, Flavomycin growth promoter antibiotic at 0.05% dietary level and feed additive mixture consisting of thyme and oregano plant extracts and propionic acid and zinc supplement at 0.1% dietary level which fed to laying hens for 42 days (3 periods of two weeks each). The results of this study showed that the utilization of feed additive mixture significantly (P<0.05) improved feed conversion ratio, egg production percentage and blood serum antibody titers against avian Influanza and low-density lipoprotein compare to control group. The blood serum antioxidant indices including Selenium, vitamin E, Superoxide dismutase and Glutathione peroxidase were significantly (P<0.05) enhanced in laying hens fed diet containing feed additive mixture in comparison with two other treatment groups. The experimental treatments had no significant effect on egg qualitative traits and blood biochemical parameters with the exception of low-density lipoprotein. According to the results of this experiment, it seems that the studied feed additive mixture can be used as a replacement for growth promoter antibiotic in laying hen diets.
