چکیده

این آزمایش به منظور تعیین اثرات آنزیم­های تجاری ناتافوس و سافیزیم در جیره­های غذایی حاوی سبوس برنج بر عملکرد جوجه­های گوشتی با استفاده از 200 قطعه جوجه از هیبرید تجاری رأس 308 در قالب یک طرح کاملاً تصادفی با پنج تیمار آزمایشی و چهار تکرار انجام شد. پنج جیره آزمایشی شامل جیره بر پایه ذرت و سویا (شاهد)، جیره حاوی سبوس برنج، جیره حاوی سبوس برنج + آنزیم ناتافوس، جیره حاوی سبوس برنج + آنزیم سافیزیم و جیره حاوی سبوس برنج + ناتافوس + سافیزیم بود. مقدار سبوس برنج در جیره‌ها در دوره­های آغازین، رشد و پایانی به­ترتیب 15، 20 و 25 درصد بود. نتایج نشان داد که جیره­های حاوی سبوس برنج و آنزیم نسبت به جیره حاوی سبوس و بدون آنزیم به مقدار کمتری مصرف شدند (05/0P<). افزودن آنزیم به جیره­های حاوی سبوس برنج، میزان افزایش وزن و ارتفاع پرزهای روده را افزایش داد (05/0P<). نتایج نشان داد که افزودن آنزیم ناتافوس یا سافیزیم به جیره­های حاوی 15، 20 و 25 درصد سبوس برنج، به ترتیب در دوره­های آغازین، رشد و پایانی و همچنین کل دوره بر عملکرد جوجه­های گوشتی اثر مثبت دارد.

چکیده [English]

The effects of phytase and glycosidase supplementation to diets containing rice bran on broiler performance were investigated by using 200 day old (308 Ross) broiler chicks in a completely randomized design with five treatments and four replicates. The five dietary treatments were as: corn-soybean meal based diet; diet containing rice bran; diet containing rice bran supplemented with Natafous; diet containing rice bran supplemented with Safizyme, and diet containing rice bran supplemented with Natafous and Safizyme. The dietary levels of rice bran were 15, 20 and 25 percent for the starting, growing and finishing diets, respectively. Birds fed on rice bran + enzyme added diets consumed less feed (P< 0.05) than those fed on unsupplemented rice bran contained diets. The enzyme addition to rice bran containing diets improved the villi length and weight gain of birds at different rearing periods (P< 0.05). In conclusion, results showed that the Natafous or Safizyme supplementation in diets could improve the performance of broiler chicks when rice bran was used at a level of 15, 20 and 25 percent in starter, grower and finisher diets, respectively.
