چکیده

این آزمایش جهت بررسی اثر آلومینوسیلیکات، اسید هیومیک، دیواره سلولی مخمر، پودر گیاهی و یک توکسین بایندر تجاری برای کاهش آثار آفلاتوکسین B1 در جیره جوجه‌های گوشتی انجام شد. آزمایش با استفاده از 320 قطعه جوجه­­گوشتی در قالب طرح کاملاً تصادفی با 8 تیمار، 4 تکرار و 10 قطعه پرنده در هر تکرار از سن 7 تا 28 روزگی انجام شد. تیمار­های آزمایشی شامل: 1) شاهد منفی (بدون آفلاتوکسین)، 2) شاهد مثبت (حاوی 3/0 میلی­گرم آفلاتوکسینB1 در کیلوگرم جیره)، 3) شاهد مثبت + آلومینوسیلیکات، 4) شاهد مثبت+ آلومینوسیلیکات+ اسید هیومیک، 5) شاهد مثبت+ آلومینوسیلیکات+ دیواره سلولی مخمر، 6) شاهد مثبت+ آلومینوسیلیکات+ اسید هیومیک+ دیواره سلولی مخمر، 7) شاهد مثبت+ توکسین بایندر تجاری مگنوتوکس و 8) شاهد مثبت+ پودر گیاهی بود. استفاده از جیره حاوی آفلاتوکسین سبب کاهش عملکرد رشد جوجه‌ها، افزایش وزن کبد، قلب و پانکراس و کاهش غلظت آلبومین، پروتئین کل و گلوکز سرم شد (05/0>P). افزودن آلومینوسیلیکات به‌عنوان جاذب به تنهایی در کاهش آثار منفی آفلاتوکسین مؤثر بود. افزودن دیواره سلولی مخمرسبب تقویت اثرات آلومینوسیلیکات شد، اما افزودن اسید هیومیک زیاد مؤثر نبود. در مجموع، به نظر می­ رسد ترکیب آلومینوسیلیکات و دیواره سلولی مخمر بیشترین جذب آفلاتوکسین B1 را دارا می­باشد.

چکیده [English]

The experiment was carried out to investigate the effect of aluminum silicate (AS), humic acid (HA), Saccharomyces cerevisiae cell wall (SC), herbal powder (HP) and a commercial toxin binder to alleviate the effects of aflatoxin B1 (AFB1) in broiler diet.  In this experiment we used 320 day old chicks in a completely randomized design with 8 treatments and 4 replications, and 10 birds in each replicate, from 7 to 28 days of age. Experimental treatments were: 1) negative control (NC; without AFB1), 2) positive control (PC; contaminated by 0.3 mg AFB1 / kg diet), 3) PC + AS, 4) PC + AS + HA, 5) PC + AS + SC, 6) PC + AS + HA + SC, 7) PC + Magnotox as a commercial binder and 8) PC + HP. Feeding AFB1 contaminated diet reduced broiler performance, increased relative weights of liver, heart, pancreas and reduced serum albumin, total protein and glucose concentrations (P <0.05). Inclusion of AS in PC diet individually improved the negative effects of AFB1. However, supplementation of SC boosted AS effects, HA supplementation was rarely effective. Finally, it can be concluded that the combination of AS + SC has the highest adsorbing ability of AFB1.
