این آزمایش به منظور تعیین معادلات پیش بینی اسید آمینه های قابل هضم استاندارد شده ایلئومی (SID) پودر گوشت طیوری بر اساس ترکیبات شیمیایی آن انجام شد. تعداد 270 قطعه جوجه گوشتی نر یک روزه نژاد راس 308 در یک طرح کاملا تصادفی در نه گروه آزمایشی (پنج تکرار/شش قطعه پرنده در هر تکرار) استفاده شد. گروه های آزمایشی شامل هشت جیره نیمه خالص که هر کدام حاوی یکی از منابع پودر گوشت طیوری به عنوان تنها منبع پروتئین جیره بود و همچنین یک جیره عاری از نیتروژن به منظور تعیین اسیدهای آمینه SID استفاده شد. در سن 28 روزگی، همه پرندگان کشتار شده و نمونه های ماده هضمی از ناحیه ایلئوم جهت اندازه گیری خاکستر نامحلول در اسید و اسید آمینه ها جمع آوری شد. از بین اسید آمینه هایSID اندازه گیری شده، برای مثال اسید امینه های متیونین و لیزین به ترتیب از 52/0 تا 89/0درصد و 88/1 تا 44/2 درصد متغیر بود (P<0.05). در نهایت، با توجه به شاخص های آماری ضریب تبیین تطبیق داده شده و خطای استاندارد پیشبینی، بهترین معادلات برای 10 اسید آمینهSID براورد شد که به عنوان مثال معادلات پیشبینی اسیدهای آمینهSID لیزین، متیونین، متیونین+سیستین و ترئونین پیشنهاد شد: dLys =0.937 + 0.022 × CP - 0.057 × Ash (SEP 0.033; Adjusted R2 0.966) dMet =0.055 + 0.009 × CP (SEP 0.550; Adjusted R2 0.806) dMet + dCys = 0.250 × CP (SEP 0.114; Adjusted R2 0.994) dThr = 0.023 × CP + 0.015 × EE (SEP 0.085; Adjusted R2 0.997) | ||

چکیده [English] | ||
This experiment was conducted to determine the prediction equations of standardized ileal digestible amino acids) SID (contents of poultry by-products meal (PBM) based on its chemical compositions. A total of 270 one-day-old Ross 308 male broiler chicks in nine dietary treatments (five replicates/six birds) were used. The treatments were included eight semi-purified diets containing each of PBM as the only source of dietary protein and one nitrogen free diet in order to determine SID amino acids. On day 28, the birds were euthanized to collecting ileal digesta for further analyses of acid insoluble ash and amino acids. The SID contents of Met and Lys was varied from 0.52 to 0.89% and 1.88 to 2.46%, respectively (P< 0.05). Finally, according to adjusted coefficient of determination and standard error of prediction the best prediction equations were selected to predict 10 SID amino acids of PBM. For example, the prediction equations of Lys, Met, Met + Cys and Thr was recommended as: dLys = 0.937 + 0.022 × CP - 0.057 × Ash (SEP 0.033; Adjusted R2 0.966) dMet = 0.0550 + 0.009 × CP (SEP 0.550; Adjusted R2 0.806) dMet + dCys = 0.250 × CP (SEP 0.114; Adjusted R2 0.994) dThr = 0.023 × CP + 0/015 × EE (SEP 0.085; Adjusted R2 0.997) | ||
