| در این پژوهش تأثیرافزودن سطوح محتلف سین‌بیوتیک به جیره برعملکرد، جمعیت میکروبی و ریخت‌سنجی روده‌کوچک جوجه‌های گوشتی در شرایط تنش گرمایی مزمن بررسی و سطح بهینه سین‌بیوتیک برآورد شد. در مجموع تعداد240 قطعه جوجه گوشتی راس- 308 یک روزه، به طور تصادفی در 4 گروه آزمایشی و 5 تکرار و 12 پرنده در هر تکرار اختصاص داده شد. تیمارهای آزمایشی شامل سطوح 0، 5/0، 1 و 5/1 )گرم در کیلوگرم جیره( سین‌بیوتیک که به جیره آزمایشی (پایه) از 3 روزگی تا 42 روزگی اضافه گردید. تنش مزمن گرمایی برای همه گروه‌ها از روز 28 تا 42 اعمال شد (روزانه 6 ساعت، دمای 32 درجه سلسیوس از ده صبح تا 4 عصر). نتایج نشان داد تغذیه با سین‌بیوتیک باعث بهبود معنی‌دار افزایش وزن بدن و مصرف خوراک تا 28 روزگی و دوره تنش مزمن گرمایی شد (05/0≥p). بطوریکه گروه‌های دریافت‌کننده 1 و 5/1 گرم در کیلوگرم سین‌بیوتیک بالاترین عملکرد را داشتند. تیمارهای حاوی سین‌بیوتیک بر جمعیت میکروبی تأثیر معنی‌داری داشت و باعث افزایش جمعیت باکتری‌های تولیدکننده اسیدلاکتیک شد (05/0≥p). استفاده از سین‌بیوتیک در جیره باعث افزایش معنی دار ارتفاع پرز روده شد (05/0≥p). شاخص تولید اروپایی در تیمارهای حاوی 1 و 5/1 (گرم در کیلوگرم) سین‌بیوتیک افزایش معنی‌داری یافت (05/0≥p). نتایج پژوهش نشان می‌دهد که استفاده از سین‌بیوتیک در دوره تنش مزمن‌گرمایی با تغییر مثبت جمعیت میکروبی و ریخت سنجی روده، عملکرد را بهبود می‌دهد و بر اساس مدل‌سازی خطی و درجه دو، نقطه بهینه سطح سین‌بیوتیک برای افزایش وزن به ترتیب 3/1 و 42/1گرم در کیلوگرم جیره می‌باشد. | ||

| This study aimed to investigate the effects of different levels of synbiotic on performance, intestinal microbial population and morphology of broiler chicks subjected to chronic heat stress and estimation of optimal point of synbiotic using broken line modeling. In total, 240 one-day-old (Ross 308) broiler chicks were allocated into four experimental treatments with five replications (12 chicks) in complete random design. Treatments containing 0, 0.5, 1.0 and 1.5 (g/Kg) synbiotic added to experimental diet from 3 to 42 days. Chronic heat stress was induced from 28 to 42 days of age to all groups (32 degree Celsius for 6 hours, from 10:00 am to 4:00 pm).The results showed that synbiotic improved body weight gain and feed intake significantly to 28 day and during chronic heat stress (p≥0.05). So that, the groups receiving 1 and 1.5 (g/kg) of synbiotic had the highest performance. Treatments affected microbial population and caused increasing lactic-acid producing bacteria (p≥0.05). Moreover, the result showed that treatments made significant difference in intestinal morphology and increased villus height (p≥0.05). European production index significantly increased the groups receiving 1 and 1.5 (g/kg) of synbiotic (p≥0.05). The results of this study showed that using synbiotic during chronic heat stress, improved performance through positive changes in morphology and microbial population of intestine. Based on linear and quadratic broken line modeling, the optimal point of synbiotic are 1.3 and 1.42 (g/Kg diet) respectively. | ||
