چکیده

مطالعه حاضر به‌منظور تأثیر استفاده از مکمل گیاهی ویتامین E بر صفات تولیدی، پاسخ‌های ایمنی هومورال و برخی فراسنجه‌های خونی با استفاده از تعداد 480 قطعه جوجه گوشتی یک‌روزه آرین در قالب طرح کاملاً تصادفی با چهار تیمار، چهار تکرار و 30 قطعه پرنده در هر تکرار بررسی شد. تیمارهای آزمایشی شامل 1- جیره پایه (حاوی 25 واحد بین‌المللی ویتامین E سنتتیک)، 2- جیره پایه+ 25 واحد بین‌المللی ویتامین E سنتتیک، 3- جیره پایه+ 50 میلی‌گرم مکمل گیاهی ویتامین E، 4- جیره پایه+ 100 میلی‌گرم مکمل گیاهی ویتامین E بود. نتایج نشان داد که تیمارهای آزمایشی بر مصرف خوراک، وزن بدن و ضریب تبدیل غذایی تأثیر  معنی‌داری نداشتند، هم‌چنین خصوصیات لاشه از جمله درصد لاشه، درصد سینه، ران، پشت و گردن، چربی حفره بطنی، قلب، طحال و فراسنجه‌های خونی تحت تأثیر تیمارهای آزمایشی قرار نگرفتند استفاده از مکمل گیاهی ویتامین E بر تیتر آنتی‌بادی علیه ویروس نیوکاسل و آنفلوآنزا  بی‌تأثیر  بود. به‌طور کلی، با توجه به توصیه سویه‌های تجاری نیاز ویتامین E 50 واحد بین‌المللی است، لذا در صورت تأمین 25 واحد بین‌المللی ویتامین E سنتتیک در جیره، امکان تأمین بقیه نیاز تا 50 واحد بین‌المللی با استفاده از مکمل گیاهی ویتامین (به میزان 50 میلی‌گرم در هر کیلوگرم خوراک) وجود دارد.

چکیده [English]

Introduction: Vitamins play an important role in improving the performance, immune system, and growth of birds. In recent years, due to the increase of the price of synthetic vitamin supplements and also due to the limitation of the use of commercial antioxidants, plant-based antioxidant sources have been considered in the poultry industry. Therefore, this study aimed to investigate the effects of herbal vitamin E supplements on production traits, humoral immune responses, and some blood parameters of broiler chickens.
Material and method: In a completely randomized design 480 Arian broiler chickens (one-day-old, mixed sexes) were allocated to four treatments, four replicates, and 30 birds in each replicate. Experimental treatments included: 1. basal diet (Contains 25 IU of synthetic vitamin E), 2. basal diet + 25 IU synthetic vitamin E, 3. basal diet + 50 mg herbal vitamin E supplement, and 4. basal diet + 100 mg herbal vitamin E Supplement. In this experiment, weight gain, feed intake, and feed conversion ratio (FCR) were measured. On day 40, two birds per replicate were randomly selected, weighed, and killed, and then the entire empty carcass and parts of the carcass including breast, thigh, neck back, and wings, abdominal fat, and some organs including heart and spleen were weighed. One day 40 days, to measure the concentration of total protein, albumin, triglyceride, cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and the activity of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase enzymes, blood was collected from each replicate of 4 birds. On day 33 to measure antibody titer against Newcastle disease and influenza, 1 ml SRBC was injected into 4 birds in each repetition.
Result and discussion:  The results showed that the experimental treatments had no effects on feed intake, body weight, and FCR. Also, carcass characteristics including carcass percentage, breast, thigh, back, and neck percentage, abdominal fat, heart, spleen, and blood parameters were not affected by experimental treatments. Antibody titer against sheep red blood cell injection had no significant effect.
Conclusion: In total, according to the recommendation of commercial strains, the requirement of vitamin E is 50 IU, therefore in case of providing 25 IU of synthetic vitamin E in the diet, it is possible to provide the rest of the need up to 50 IU by using the herbal vitamin E supplement (at the rate of 50 mg per kilogram of feed) considering there are economic considerations.
