چکیده

به‌منظور مقایسه تأثیر منابع مختلف فیبر و پری‌بیوتیک بر عملکرد و برخی صفات فیزیولوژیکی جوجه‌های گوشتی، آزمایشی با استفاده از 320 قطعه جوجۀ گوشتی در قالب طرح کاملاً تصادفی با هشت تیمار انجام شد. تیمارهای آزمایشی شامل جیره شاهد (ذرت- کنجاله سویا)، جیره شاهد به‌همراه پری‌بیوتیک (بیولکس MB40) و منابع مختلف فیبر (سبوس گندم، پوسته سویا و پودر هسته خرما) بودند. منابع مختلف فیبر در سطوح 5/1 و سه درصد و پری‎بیوتیک به مقدار دو گرم در کیلوگرم به جیره‎‌های آزمایشی اضافه شدند. تیمار دارای 5/1 درصد پودر هسته خرما، بهترین ضریب تبدیل خوراک را در مقایسه با سایر تیمارها به‌جز تیمار دارای سه درصد پودر هسته خرما و شاهد داشت (05/0>P). چربی حفره بطنی در پرندگان دریافت‌کننده منابع مختلف فیبر در مقایسه با تیمار شاهد کاهش یافت (05/0>P). قابلیت هضم ایلئومی ظاهری ماده آلی و پروتئین خام در جیره حاوی سه درصد پودر هسته خرما افزایش یافت (05/0>P). قابلیت هضم  ایلئومی ظاهری چربی خام، در پرندگان مصرف‌کننده پودر هسته خرما به‌طور معنی‌داری نسبت به تیمار شاهد کاهش یافت (05/0>P). استفاده از منابع مختلف فیبر سبب کاهش معنی‎دار تری‎گلیسرید و کلسترول سرم خون در مقایسه با تیمار شاهد شد (05/0>P). نتایج نشان داد که افزودن پودر هسته خرما به جیره غذایی جوجه‎های گوشتی سبب بهبود عملکرد، کاهش چربی محوطه شکمی و جمعیت‎های میکروبی ایکولای و کلی‌فرم و افزایش قابلیت هضم پروتئین خام و جمعیت میکروبی لاکتوباسیل‎ها در سکوم جوجه‌های گوشتی گردید.

چکیده [English]

In order to compare the effect of prebiotic and various types of fibers on performance and some physiological parameters of broiler chickens, an experiment was performed with 320 chicks with eight treatments in a completely randomized design. Dietary treatments were basal diet (corn-soybean meal), basal diet with prebiotic (Biolex, MB40), and various sources of fiber (wheat bran (WB), soybean hull (SH), and palm kernel meal (PKM)). Different types of fiber and prebiotics were added to the diet at 1.5,3% and 2 g/kg, respectively. The birds that consumed 1.5% of PKM had the best feed conversion ratio compared to the other treatments except 3% of PKM and control diet (P<0.05). Abdominal fat pad significantly decreased in birds that consumed various types of fiber compared to the control diet (P<0.05). Apparent ileal digestibility of organic matter and crude protein increased in birds that consumed 3% palm kernel meal (P<0.05). The apparent ileal digestibility of ether extract decreased in birds that consumed PKM compared to the control diet (P<0.05). Dietary inclusion of various types of fiber caused a significant decrease in plasma cholesterol and triglycerides compared to the control diet (P<0.05). The results showed that dietary inclusion of PKM improved performance, decreased abdominal fat pad and E.coli and coliform population of cecum and increased digestability of crude protein and population of Lactobacillus of cecum in broiler chickens.
