Abstract :

این آزمایش به منظور تعیین ترکیب شیمیایی و انرژی متابولیسمی پودر ضایعات کشتارگاهی طیور حاصل از دو کشتارگاه صورت پذیرفت. ماده خشک، پروتئین خام، خاکستر، عصاره اتری و انرژی خام نمونه‌ها مورد آزمایش قرار گرفتند. مقادیر کلسیم، فسفر، سدیم، پتاسیم، منیزیم، آهن، منگنز، مس و روی اندازه‌گیری شدند. انرژی متابولیسم ظاهری (AME)، انرژی متابولیسم ظاهری تصحیح شده برای ازت (AMEn)، انرژی متابولیسم حقیقی (TME) و انرژی متابولیسم حقیقی تصحیح شده برای ازت (TMEn) بر حسب کیلوکالری برگرم بر اساس روش سیبالد تعیین گردید. برای این منظور از دوازده قطعه خروس نیوهمپشایر با سن 230 روزه استفاده شد. بین انواع انرژی متابولیسمی در نمونه‌ها تفاوت معنی‌داری مشاهده نشد. همچنین میزان اسیدهای آمینه قابل هضم استاندارد تعیین گردید. بیشترین و کمترین میزان مربوط به لوسین و تریپتوفان بود. نتایج این تحقیق نشان داد که بین نمونه‌های مختلف پودر ضایعات کشتارگاهی طیور تفاوت وجود دارد.
