چکیده
هدف این مطالعه، ارزیابی تأثیر سطوح مختلف هیدروکسی کلرید روی (HCZ) بر فراسنجه های مرتبط با فشار خون ریوی، ذخیره عنصر روی و استحکام استخوان درشت نی جوجه‌های گوشتی در شرایط محیطی با ارتفاع بالا از سطح دریا (2100 متر) بوده است. در این پژوهش از 200 قطعه جوجه خروس سویه راس 308 از سن 23 تا 42 روزگی برای اجرای یک طرح کاملاً تصادفی در قالب 4 تیمار و 5 تکراراستفاده شد. تیمارهای آزمایشی شامل ﺟﻴﺮﻩ ﭘﺎﻳﻪ و 25، 50 و 75 میلی‌گرم HCZ در هر کیلوگرم خوراک پایه بود که به جیره شاهد ﺍفزوده شد. مصرف HCZ باعث کاهش نسبت RV به TV ، افزایش غلظت نیتریک اکساید، کاهش هماتوکریت و نسبت هتروفیل به لنفوسیت گردید (05/0P<). همچنانکه افزایش ذخیره‌ی عنصر روی در ماهیچه سینه، کبد و استخوان درشت نی مشاهده گردید (05/0P<)، افزایش ضربه شکست استخوان بیانگر افزایش استحکام استخوان درشت نی بود (05/0P<). به‌طورکلی نتایج نشان‌داد مصرف 75 میلی‌گرم HCZ باعث بهبود پاسخ‌های فیزیولوژیک و ایمنی، افزایش ذخیره عنصر روی در بافت استخوان، سینه و کبد، بهبود فراسنجه‌های مربوط به رشد و استحکام استخوان درشت نی و عملکرد قلبی ریوی جوجه‌های گوشتی تحت شرایط هیپوکسی گردید. بنابراین سطح 75 میلی‌گرم HCZ جهت مصرف در سطح مزارع پرورشی قابل توصیه می باشد.

چکیده English

This study aimed to evaluate the effect of different levels of zinc hydroxychloride (HCZ) on pulmonary hypertension-related parameters, zinc element storage, and tibia bone strength in broiler chickens under high-altitude environmental conditions (2100m). In this research, 200 Ross 308 male broiler chicks from 23 to 42 days of age were used for a completely randomized design in 4 treatments and 5 replicates. The experimental treatments included a basal diet and 25, 50, and 75 mg of HCZ per kg of basal feed, which were added to the control diet. HCZ consumption led to a decrease in the RV to TV ratio, an increase in nitric oxide concentration, a decrease in hematocrit, and a decrease in the heterophil to lymphocyte ratio (P<0.05). As the retention of zinc in breast muscle, liver, and tibia bone increased (P<0.05), the increased bone fracture force indicated an increase in tibia bone strength (P<0.05). Overall, the results showed that consuming 75 mg of HCZ improved physiological and immune responses, increased zinc storage in bone tissue, breast, and liver, improved growth parameters and tibia bone strength, and cardiopulmonary performance of broiler chickens under hypoxic conditions. Therefore, a level of 75 mg HCZ is recommended for use in poultry farms.
