| چکیده | ||
| این مطالعه، با هدف بررسی تأثیر سطوح مختلف ویتامین E و ال-کارنیتین بر عملکرد و برخی فراسنجههای خونی و ایمنی جوجه‌های گوشتی تحت تنش گرمایی در قالب طرح کاملاً تصادفی با آرایش فاکتوریل۳Í۳ با ۳ سطح ویتامین E (صفر، ۱۰۰ و ۲۰۰ میلی‌گرم بر کیلوگرم) و ۳ سطح ال-کارنیتین (صفر، ۵۰ و ۱۰۰ میلی‌گرم بر کیلوگرم) انجام شد. از ابتدای هفته چهارم تنش حرارتی اعمال شد و تمام جوجه‌ها در محدوده دمایی ۳۸-۲۴ درجه سانتی‌گراد نگهداری شدند. فراسنجههای عملکردی به‌صورت هفته‌ای رکوردبرداری شدند. در سنین ۲۸ و ۳۵ روزگی تیتر آنتی‌بادی علیه SRBC بررسی شد. در 42 روزگی، خصوصیات لاشه بررسی و خون‌گیری جهت اندازه‌گیری فراسنجههای خون انجام شد. سطوح مختلف ویتامین E و ال-کارنیتین تأثیر معنی‌داری بر عملکرد در طول دوره پرورش نداشتند. مکمل نمودن ویتامین E به جیره، وزن بورس فابریسیوس را افزایش (05/0 P<) ومکمل ال- کارنیتین، درصد چربی محوطه بطنی را کاهش داد (01/0P<). مکمل نمودن ۵۰ میلی‌گرم ال- کارنیتین در کیلوگرم جیره موجب افزایش تیتر آنتی‌بادی علیه SRBC طی پاسخ اولیه شد (05/0P<). افزودن ویتامین E و ال-کارنیتین به جیره غلظت تری گلیسرید سرم خون را کاهش داد. با توجه به نتایج این پژوهش به نظر میرسد که سطوح مختلف ویتامین E و ال- کارنیتین در شرایط تنش گرمایی بدون تاثیر معنیدار بر عملکرد، می‌تواند چربی محوطه بطنی و تریگلیسرید سرم خون را کاهش دهد و سبب بهبود پاسخ ایمنی در جوجه‌های گوشتی شود. | ||

| چکیده [English] | ||
| This study was conducted to investigate effects of different levels of vitamin E (0, 100 and 200 mg/kg) and L-carnitine (0, 50 and 100 mg/kg) on growth performance and some blood and immune parameters of broilers under heat stress, using completely randomized design with 3Í3 factorial treatment arrangement and 4 replicates pertreatment. Heat stress was induced from the beginning of forth week. Performance parameters were recorded weekly. At 28 and 35 days of age, antibody titer against SRBC was determined. At 42 days of age, blood samples were collected and carcass characteristics analysis was done. Levels of vitamin E and L-carnitine had no significant effect on performance parameters. Vitamin E increased the weight of the bursa of fabricius (P<0.05) and L-carnitine decreased abdominal fat percentage (P<0.01). L-carnitine at 50 mg/kg of diet increased antibody titer against SRBC during the primary response (P<0.05). Supplementing diet with vitamin E and L-carnitine just decreased serum triglyceride. According to the results of this experiment, it appears that different levels of vitamin E and L-carnitine were not effective on performance parameters but decreased abdominal fat percentage and blood triglyceride and improved immune response of chickens. | ||
