| چکیده | ||
| به منظور بررسی اثرات پروبیوتیک پریمالاک و پری‌بیوتیک فرماکتو به تنهایی و یا توأمان بر عملکرد رشد، قابلیت هضم ایلئومی مواد مغذی، ریخت‌سنجی مخاط روده و برخی فراسنجه‌های بیوشیمیایی خون، آزمایشی با استفاده از 256 قطعه جوجه گوشتی سویه تجارتی راس-308 در قالب یک طرح کاملاً تصادفی اجرا شد. چهار تیمار آنتی‌‌‌بیوتیک آویلامایسین (شاهد)، پریمالاک، فرماکتو و مخلوط پریمالاک و فرماکتو در چهار تکرار به جیره‌های پایه افزوده شده و به مدت 42 روز به جوجه‌ها تغذیه شد. استفاده از پریمالاک و فرماکتو با کاهش مصرف خوراک (01/0P<) موجب کاهش وزن جوجه‌ها شد (001/0P<). ضریب تبدیل غذایی در اثر مصرف جیره‌های حاوی پریمالاک بدتر شد (05/0P<). pH محتویات سنگدان و سکوم تحت تأثیر تیمارهای آزمایشی قرار نگرفت. قابلیت هضم ایلئومی انرژی توسط تیمارهای آزمایشی کاهش نشان داد (05/0P<). کاهش ارتفاع پرز ژژنوم در اثر پریمالاک و فرماکتو و افزایش عمق کریپت آن در اثر همه تیمارها مشاهده شد (01/0P<). استفاده از پریمالاک و فرماکتو و ترکیب این دو باعث کاهش کلسترول و کلسترول LDL (001/0P<) و مصرف این افزودنی‌ها به تنهایی موجب افزایش کلسترول HDLسرم خون جوجه‌های گوشتی شد (05/0P<). به‌طور کلی استفاده از پریمالاک و فرماکتو و یا ترکیب آنها در جیره، به جز کاهش سطح کلسترول سرم خون نتوانستند در مقایسه با آویلامایسین اثرات مشابهی بر عملکرد جوجه‌ها نشان دهند. از این‌رو نمیتوانند جایگزین خوبی برای این آنتی‌‌‌بیوتیک محرک رشد مطرح شوند. به علاوه بین پریمالاک و فرماکتو ویژگی سینبیوتیکی مشاهده نشد. | ||

| چکیده [English] | ||
| To evaluate the effects of Primalac probiotic and Fermacto prebiotic, alone or combined, on growth performance, ileal nutrients digestibility, intestinal mucosal morphometry and some blood biochemical parameters, a trial was conducted using 256 broiler chicks (Ross 308) by employing a completely randomized design. Four treatments including Avilamycin antibiotic (control), Perimalac, Fermacto and Perimalac plus Fermacto with four replicates were added to the basal diets and fed to birds for a period of 42 days. Primalac and Fermacto decreased feed intake (P<0.01) and lowered weight gain of the chickens (P<0.001). Feed conversion ratio was depressed by Perimalac containing diets as compared to the control (P<0.05). pH value of gizzard and cecal digesta was not affected by the treatments. Ileal digestibility of energy was decreased by the experimental treatments (P<0.05). Decreased villus height as the effect of Perimalac and Fermacto and increased crypt depeth as the effect of all treatments were observed (P<0.01). Applying Primalac, Fermacto and their combination in the diet declined total and LDL-cholesterol levels (P<0.001) while these two additives alone enhanced HDL-cholesterol levels of broilers sera (P<0.05). In overall, using Primalac and Fermacto alone or combined, except lowering effect on serum cholesterol, failed to show any similar effects as Avilamycin on broilers performance. In conclusion, Primalac and Fermacto could not be replaced for the growth promoter antibiotic. Moreover, no synbiotic characteristic was observed between Perimalac and Fermacto. | ||
