| چکیده | ||
| برای بررسی تأثیرات افزودن ویتامین E و C به جیرههای حاوی منابع متفاوت روغن بر عملکرد و فراسنجههای سرم از 320 قطعه جوجۀ گوشتی (سویۀ راس 308)، در آزمایشی فاکتوریل 2×2×2 و در قالب طرح کاملاً تصادفی با هشت تیمار، چهار تکرار و 10 قطعه جوجه در هر تکرار استفاده شد. فاکتورهای آزمایشی شامل دو منبع متفاوت روغن (سویا و کانولا) و دو سطح ویتامین E (صفر و 200 میلیگرم در کیلوگرم) و دو سطح ویتامین C (صفر و 1000 میلیگرم در کیلوگرم) بودند. منابع روغن و ویتامینهای E و C اثر معنیداری بر عملکرد جوجۀ گوشتی نداشتند. استفاده از ویتامین E یا C سبب افزایش کلسترول کل و HDL سرم شد (05/0>P). منبع روغن اثر معنیداری بر کلسترول کل و گلوکز سرم نداشت. جیرههای حاوی روغن کانولا، سبب افزایش HDL و کاهش مالوندیآلدئید سرم در مقایسه با جیرههای حاوی روغن سویا شد (01/0>P). جیرۀ حاوی روغن کانولا و ویتامین C، موجب کاهش تریگلیسیرید سرم در مقایسه با جیرههای حاوی روغن سویا و ویتامین C شد (05/0>P). جیرههای حاوی ویتامین E موجب کاهش مالوندیآلدئید و افزایش فعالیت آنزیم گلوتاتیون پراکسیداز سرم شد (05/0>P). براساس نتایج تحقیق حاضر، تغذیۀ جوجههای گوشتی با جیرۀ حاوی روغن کانولا، ویتامین C یا E، HDL سرم را افزایش میدهد و ویتامین E با تقویت سیستم آنتیاکسیدانی سبب کاهش اکسیداسیون لیپیدهای سرم شد. | ||

| چکیده [English] | ||
| An experiment was conducted to determine of the effects of vitamin E and C supplementation in diet based on different source of oils on performance and serum parameters of broilers. A total of 320 broiler chicks (Strain Ross 308) used in a 2×2×2 factorial arrangement in the form of completely randomized design with eight treatments, four replicates and 10 chicks in each replicate. Experimental factors included: two different oil sources (soybean and canola), two levels of vitamin E (zero and 200 mg/kg), and two levels of vitamin C (0 and 1000 mg/kg). Oil sources and vitamin E and C had no effect on performance of broilers. Supplementation of vitamin E or C increased serum total cholesterol and HDL (P<0.05). Source of oil had no significant effect on glucose and total serum cholesterol. Broilers fed diet containing canola oil had higher HDL and lower serum malondialdehyde than those fed diets with soybean oil (P<0.01). Supplementation of vitamin C to the diets containing canola oil decreased serum triglyceride compared with diets include soybean oil and vitamin C (P<0.05). Supplementation of vitamin E decreased serum malondialdehyde and increased activity of glutathione peroxidase (P<0.05). Results of this study indicate that dietary supplementation of canola oil, vitamin C or E to broiler diet increased serum HDL and vitamin E decreased oxidation of serum lipids by improving antioxidant system. | ||
