چکیده

استفاده از گیاهان دارویی از قدیم در سلامت انسان، دام و طیوراهمیت فراوان داشته و در سال‌های اخیر به منظور بهبود کارکرد سیستم ایمنی و سلامت دستگاه گوارش مورد توجه بیشتری قرار گرفته‌اند. این آزمایش به منظور بررسی اثر سطوح مختلف سیاه دانه برمولفه‌های رشد، فراسنجه‏های خونی و ریخت‌شناسی ژژنوم جوجه‏های گوشتی انجام شد. آزمایش با استفاده از 250 قطعه جوجه راس 308 در قالب طرح کاملاً تصادفی با پنج تیمار و پنج تکرار صورت پذیرفت. تعیین فراسنجه‏های بیوشیمیایی خون در 42 روزگی انجام شد. پس از تزریق نیم % گلبول قرمز گوسفندی در هفت و 14 روزگی، در روزهای 21 و 28 خون‌گیری برای ارزیابی سیستم ایمنی به انجام رسید. افزودن نیم % سیاه دانه سبب بهبود معنی‏دار افزایش وزن بدن و ضریب تبدیل غذایی شد. کاهش کلسترول و تری‌گلیسرید،افزایش HDL و بیلی‌روبین با افزودن سیاه دانه مشاهده شد. تفاوت مقادیر ایمونوگلوبین‌ تام، ایمونوگلوبین M و ایمونوگلوبین G در 21 و 28 روزگی معنی‌داری نبود (05/0<P). با مصرف سطوح مختلف سیاه دانه، متغیرهای ریخت‌شناسی ژژونوم شامل طول پرز، عرض پرز، عمق کریپت، مساحت پرز، تراکم پرز و مساحت منطقه جذب افزایش معنی‌داری داشتند (05/0>P). نتایج این آزمایش نشان داد، افزودن سیاه دانه تا یک % سبب بهبود عملکرد رشد جوجه‏های گوشتی می‏شود.

چکیده [English]

The use of medicinal plants has long been important in human, animal and poultry health and in recent years to improve the functioning of the immune system and gastrointestinal tract have received more attention. This experiment was performed to investigate the effect different levels of black seed on growth indices, blood parameters and morphology of broiler jejunum. This experiment was performed with 250 308 Ross chickens in a completely randomized design with five treatments and five replications. Blood samples were taken to determine blood parameters at42 days of age. Blood samples were taken on days 21 and 28 to evaluate the immune system after injection of 0.5% of sheep red blood cells at seven and 14 days. Addition of 0.5% of black seed significantly improved body weight gain and feed conversion ratio. Decreased cholesterol and triglyceride, increased HDL and bilirubin were observed with the addition of black seed. There was no significant difference in total immunoglobulin, immunoglobulin M and immunoglobulin G at 21 and 28 days. Consumption of different levels of black seed, jejunum morphological variables including villi length, villi width, crypt depth, villi area, villi density and area of adsorption area increased significantly. The results of this experiment showed that the addition of black seed up to one percent improves the growth performance of broilers.
