| در پژوهش حاضر، اثر سطوح مختلف پودر برگ گیاه دارویی گزنه بر عملکرد رشد، مورفولوژی روده کوچک و شاخص‌های در پژوهش حاضر، اثر سطوح مختلف پودر برگ گیاه دارویی گزنه بر عملکرد رشد، مورفولوژی روده کوچک و شاخص‌های مرتبط با آسیت در جوجههای گوشتی پرورش یافته در شهرکرد بررسی شد. تعداد 240 قطعه جوجه خروس گوشتی یک روزه سویه تجاری راس 308 در قالب طرح کاملاً تصادفی با 4 تیمار، 4 تکرار و 15 قطعه جوجه در هر تکرار در یک دوره آزمایشی به مدت 42 روز مورد استفاده قرار گرفتند. تیمارهای آزمایشی شامل گروه شاهد (فاقد پودر برگ گزنه) همراه با سه سطح 5/0، 1 و 5/1 درصد پودر برگ گزنه بودند. نتایج این آزمایش نشان داد که افزودن پودر برگ گزنه به جیره سبب بهبود افزایش وزن بدن و ضریب تبدیل غذایی (05/0P<) شد. استفاده از پودر برگ گزنه در جیره موجب افزایش ارتفاع و عرض پرزها و افزایش سطح جذب آنها در قسمت‌های مختلف روده کوچک (دوازدهه، ژژنوم و ایلئوم) نسبت به گروه شاهد (05/0P<) گردید. همچنین تغذیه با پودر برگ گزنه در سطوح 1 و 5/1 درصد از هیپرتروفی بطن راست قلب جلوگیری نمود و افزایش بیان ژن‌های سوپراکسید دیسموتاز 1 و کاتالاز در بافت کبد جوجههای گوشتی را به همراه داشت. به طور کلی، نتایج این مطالعه نشان دادند که استفاده از 1 و 5/1 درصد پودر برگ گیاه دارویی گزنه می‌تواند در جلوگیری از سندرم فشار خون ریوی بالا در جوجههای گوشتی پرورش یافته در ارتفاعات سودمند باشد. | ||

| چکیده [English] | ||
| In the current research, the effect of different levels of dietary Urtica dioica leaf powder was investigated on growth performance, small intestine morphology and ascites indicators in broiler chickens reared in Shahrekord. A total of 240 one-day old male Ross 308 broiler chicks were used in a completely randomized design with 4 treatments and 4 replicates of 15 birds in each pen in an experimental period for 42 days. The experimental treatments included control group (without Urtica dioica leaf powder) and three levels of Urtica dioica leaf powder (0, 0.5, 1, and 1.5%). The results of this experiment showed that the dietary inclusion of Urtica dioica leaf powder improvement in body weight gain and feed conversion ratio (P<0.05). The dietary utilization of 1 and 1.5 percent Urtica dioica leaf powder increased villus height and width and its absorptive surface area in different parts of small intestine (duodenum, jejunum and ileum) as compared with control group. Also, the dietary inclusion of 1 and 1.5 percent Urtica dioica leaf powder prevented right ventricular hypertrophy and increased the expression of Superoxide dismutase 1 (SOD1) and Catalase genes in liver tissue of broilers. Generally, the results of this study showed that the use of 1 and 1.5 percent of medicinal plant Urtica dioica can be beneficial in prevention of pulmonary hypertension syndrome (PHS) in broiler chickens reared at high altitudes. | ||
