| چکیده | ||
| این آزمایش به منظور بررسی مقایسه عصاره‌های آویشن باغی (Thymus vulgaris L.)، سرخارگل (Echinacea purpurea (L.) Moench.)، سیر (Allium sativum L.) و آنتی‌بیوتیک ویرجینیامایسین به‌عنوان بهبود دهنده‌های رشد بر عملکرد جوجه‌های گوشتی انجام شد. تعداد 480 قطعه جوجه یک روزه از سویه رأس 308 در قالب طرح کامل تصادفی با 6 تیمار (شامل عصاره‌های آویشن باغی، سرخارگل، سیر، مخلوط عصاره‌ها با دوز 1/0 درصد، ویرجینیامایسین با دوز 15/0 درصد و گروه کنترل) و 4 تکرار و 20 جوجه در هر تکرار به‌طور تصادفی بین قفسه‌ها تقسیم گردید. در پایان آزمایش از هر تکرار 2 قطعه پرنده با وزنی نزدیک به میانگین وزنی تکرار انتخاب و جهت بررسی درصد لاشه (100 × وزن لاشه خالی/ وزن زنده پرنده)، درصد چربی بطنی و وزن اندامهای گوارشی، کشتار گردید. نتایج بدست آمده نشان داد که در پایان هر دو مقطع 21 و 42 روزگی بیشترین و کمترین وزن بدن و افزایش وزن بدن به‌ترتیب مربوط به جوجه‌های تغذیه شده با جیره غذایی آنتی‌بیوتیک و سرخارگل بود. ویرجینیامایسین مصرف خوراک را افزایش داد، اما این اختلاف بجز با گروه سرخارگل با دیگر گروهها معنی‌دار نبود (05/0P>). در کل دورۀ پرورشی (42-1 روزگی) نیز کمترین و بیشترین ضریب تبدیل به‌ترتیب مربوط به تیمار آنتی‌بیوتیک و سرخارگل بود (05/0>P)، هر چند که در این دوره ضریب تبدیل در گروه آویشن باغی تفاوت معنی‌داری با گروه آنتی‌بیوتیک نشان نداد (05/0P>). درصد لاشه، درصد چربی بطنی و وزن اندامهای گوارشی بجز روده تفاوت معنی‌داری بین تیمارها نداشت. به‌طوری که کمترین و بیشترین وزن روده به‌ترتیب متعلق به تیمارهای آنتی‌بیوتیک و کنترل بود. | ||

| This experiment was designed to investigate the comparison of thyme (Thymus vulgaris L.), coneflower (Echinacea purpurea (L.) Moench.), garlic (Allium sativum L.) extracts and virginiamycin antibiotic as growth promoter in poultry industry on performance and carcass characteristics of Broilers. A total four hundred and eighty 1-day old male broiler (Ross strain) chicks were assigned to the basal diet (control) and basal diet supplemented with 0.15% virginiamycin, 0.1% extracts of thyme (Thymus vulgaris), coneflower (Echinacea purpurea), garlic (Allium sativum) and mixture of extracts with the same dose. At the end of the experiment two chickens from each replication were randomly selected and killed to investigate the weigh of digestive organs and fat pad. There was significant difference in feed conversion ratio (FCR) between the treatments (p0.05). Lowest and highest FCR was related to virginiamycin and coneflower (pThymus vulgaris) (p>0.05). There was no difference in carcass characteristics and fat pad except small intestinal weight. Virginiamycin had the lowest small intestinal weight but the control had the highest (p | ||
