| هدف این پژوهش بررسی پاسخ جوجههای گوشتی راس 308 به مولتی آنزیم سیزدهگانه حاوی بتا ماناناز با احتساب سطوح مختلف مواد مغذی معادل آنزیم در جیره بر پایه ذرت- سویا بود. این آزمایش در قالب طرح کامل تصادفی با 6 تیمار، 8 تکرار و 4 پرنده در هر تکرار و با استفاده از 192 قطعه جوجه خروس سویه راس 308 انجام شد. تیمار یک (کنترل مثبت) بدون استفاده از مولتی آنزیم سیزدهگانه تنظیم شد. تیمارهای 2، 3، 4 و 5 حاوی 3/0 کیلوگرم در تن مولتی آنزیم سیزدهگانه بود که به ترتیب 25، 50، 75 و 100 درصد معادل مواد مغذی آنزیم در تنظیم فرمولها لحاظ گردید. تیمار شش (کنترل منفی) مشابه تیمار 5 و بدون استفاده از مولتی آنزیم بود. صفات افزایش وزن بدن و ضریب تبدیل خوراک هر هفته اندازه‌گیری شد. در پایان دوره آزمایش تفاوت وزن و ضریب تبدیل تیمار یک و دو معنیدار نبود. تفاوت وزن بدن گروه کنترل منفی و تیمار 5 در سن 42 روزگی معنیدار بود (0001/0>P). عملکرد یکسان جوجههای تغذیه‌شده با تیمار دو، با وجود کاهش مقدار انرژی قابل سوخت و ساز، پروتئین خام و فسفر قابل دسترس، با افزودن آنزیم در مقایسه با تیمار کنترل مثبت، بیانگر پتانسیل آزاد سازی مواد مغذی توسط مولتی آنزیم است. | ||

| The aim of this study was to determine the response of the Ross 308 broilers to β-mannanase containing multi-enzyme with different percentages of nutrient equivalency values of multi-enzyme in corn-soybean based dies. A total of 192 male Ross 308 broiler chicks were used in a completely randomized design with six treatments, eight replicates, and four birds in each. Treatment one (positive control) was a normal corn-soybean meal diet without multi-enzymes. Treatments two, three, four, and five contained 0.3 kg/ton multi enzymes, using 25, 50, 75, and 100% of the nutrients equivalency value of enzyme, respectively. The sixth treatment (negative control) was like to fifth treatment but without added multi-enzyme. Body weight gain and feed conversion ratio (FCR) were assessed weekly. The results indicate, no significant difference among the treatment one and two in body weight gain and FCR. At 42 days of age, the difference in body weight of the negative control group and treatment five was significant (P<0.0001). The similar performance of birds in treatment two despite lower metabolized energy, crude protein, and phosphorus with added enzyme, comparing to the positive control group, indicating that multi-enzyme had the potential for releasing the feed nutrients. | ||
