چکیده

هدف از این تحقیق ارزیابی اثرات سیر تازه در جیره روی جمعیت اشریشیاکلی و برخی از فاکتورهای بیوشیمیایی سرم خون در جوجه‌های گوشتی بود. در مجموع 105 جوجه در شهرستان زابل برای این تحقیق استفاده شدند. در روز هفتم 96 جوجه با وضعیت بهتر انتخاب و به‌طور تصادفی به 3 گروه مساوی با 2 تکرار تقسیم شدند. جیره‌ی گروه‌های 1 (کنترل)، 2 و 3 (درمان) به‌ترتیب با مقادیر 0، 1 و 2 درصد سیر تازه مخلوط گردید. در سن 35 روزگی از هر تکرار 8 جوجه به‌طور تصادفی انتخاب و وزن شدند و از آنها نمونه خون تهیه گردید و سپس کشتار شدند. پس از کالبدگشایی غده لنفاوی بورس فابریسیوس از بدن خارج و وزن گردید. برای شمارش تعداد پرگنه‌های اشریشیاکلی در روده از محتویات ایلئوم استفاده شد. نتایج بررسی نشان داد جوجه‌هایی که سیرتازه در جیره دریافت کرده بودند افزایش معنی‌داری در وزن بورس‌ فابریسیوس را نسبت به گروه کنترل نشان دادند (05/0P<). تفاوت معنی‌داری برای جمعیت اشریشیاکلی، میزان کلسترول، تری‌گلیسرید و پروتئین تام بین گروه کنترل و گروه‌های درمان مشاهده نگردید (05/0P>).

چکیده [English]

Garlic has therapeutic and also antibacterial properties and its inclusion in broiler diets improves their feed efficiency and lowers their mortality rates.The present research intended to evaluate the effects of freshly dietary garlic cloves on the intestinal Escherichia coli population and some blood serum biochemical factors in broilers. In this study, one hundred and five day-old broiler chicks were used in Zabol. On the seventh day of age, sick birds removed and 96 chicks with better body condition were selected and randomly divided into 3 equal groups with 2 replicates. Groups 1, 2 and 3 (the control and treatment groups) received 0, 1 and 2 percent of fresh crushed garlic cloves in their diets, respectively. When the broilers were 35 days old, 8 chicks from each replicate were selected randomly, weighed and blood samples were taken from the wing veins. They were then slaughtered and their bursa of Fabricius was removed and weighed. Their ileum contents were used to determine the E. coli population. Results indicated that bursa of Fabricius weight increased in broilers receiving fresh crushed garlic cloves in their diets compared to the control group (P<0.05). There was not significant differences on E. coli population, cholesterol, triglyceride and total protein between the groups (P>0.05).
