چکیده
تأثیر پودر ریشه کاسنی، بر عملکرد، قابلیت هضم، سیستم ایمنی و ترکیبات لاشه جوجه‌های گوشتی با استفاده از 360 قطعه جوجه گوشتی یک روزه (مخلوط نر و ماده)، سویه راس 308، در قالب طرح کاملاً تصادفی با چهار تیمار و پنج تکرار در دوره سنی یک تا 42 روزگی بررسی شد. تیمارهای آزمایشی شامل جیره پایه، و جیره‌های حاوی سطوح 0/25، 0/5 و 0/75 درصد پودر ریشه گیاه کاسنی بودند. مصرف خوراک و وزن پرندگان به طور دوره‌ای اندازه‌گیری و افزایش وزن بدن و ضریب تبدیل محاسبه شد. قابلیت هضم مواد مغذی در سن 33 تا 36 روزگی اندازه‌گیری شدند. استفاده از پودر ریشه کاسنی در خوراک جوجه‌های گوشتی، سبب بهبود ضریب تبدیل در دوره یک تا 14 روزگی و 42-28 روزگی شد (p<0/05 )، اما تأثیر بر عملکرد در کل دوره آزمایش نداشت. قابلیت هضم پروتئین و چربی در جوجه‌های تغذیه شده با جیره حاوی 0/75 درصد پودر ریشه کاسنی بیشتر از جیره‌های دیگر بود (p<0/05). وزن نسبی کبد در جوجه‌های تغذیه شده با پودر ریشه کاسنی کاهش یافت (p<0/05). تغذیه جوجه‌های‌گوشتی با جیره حاوی 0/25 درصد پودر ریشه کاسنی، تعداد لنفوسیت‌ها را افزایش و تعداد هتروفیل‌ها را کاهش داد (p<0/05). بر اساس نتایج این آزمایش، استفاده از سطوح 0/25، 0/5 و 0/75 درصد پودر ریشه کاسنی در جیره جوجه‌های گوشتی اثری بر عملکرد جوجه‌های گوشتی ندارد ولی سبب بهبود فعالیت سیستم ایمنی آنها می‌شود.

چکیده [English]
The effects of chicory root powder on performance, digestibility, immune system and carcass characteristics of broilers were investigated using 360 pieces of Ross 308 strain day-old broiler chicks (male and female), in a completely randomized design with 4 treatments and 5 replicates and in a growth period of 1-42 days of age. The experimental treatments were consisted of a basal diet and diets containing the levels of 0.25, 0.50, and 0.75 percentages ofchicory root powder. Feed intake and weight of birds were measured periodically and body weight gain and feed conversion ratio were calculated. Nutrient digestibilities were measured at 33-36 days of age. The use of chicory root powder in the feed of broilers caused an improvement in feed conversion ratio at 1-14 and 28-42 days of age (P<0.05), but had no significant effect on perfomance traits in the whole of experimental period. The digestibility of protein and fat in broilers fed with 0.75% chicory root powder were higher than the other diets (P<0.05). The relative weight of liver decreased in broilers fed with chicory root powder (P<0.05). Feeding of broiler chickens with 0.25 percent dietary chicory root powder increased the number of lymphocytes and decreased the number of heterophils (P<0.05). According to the results of this experiment, the use of 0.25, 0.50 and 0.75% chicory root powder in broiler ration does not have significant effect on production performance of broiler chickens but improves the immune system activity of broilers.
