| این آزمایش به منظور تعیین سطح احتیاجات اسیدآمینه لوسین کل برای جوجه خروسهای گوشتی سویه راس 308 انجام گرفت. تعیین احتیاجات اسیدآمینه لوسین براساس شاخصهای عملکردی جوجه خروسهای گوشتی در قالب طرح کاملا تصادفی با250 قطعه جوجه خروس گوشتی یک روزه سویه راس 308 از سن 24 تا 39 روزگی در 5 تیمار و 5 تکرار (در هر تکرار 10 پرنده) انجام گردید. جیره غذایی پایه حاوی ذرت، گندم و کنجاله سویا برای مقادیر کافی تمام مواد مغذی به جز اسیدآمینه لوسین بر اساس کتابچه راهنمای مدیریتی راس 308 تنظیم شد. سطوح افزایشی اسیدآمینه لوسین به جیره غذایی پایه جهت ایجاد 5 سطح اسیدآمینه لوسین در دامنه 16/1 الی 36/1 درصد تامین گردید. افزایش وزن بدن، مصرف خوراک، ضریب تبدیل غذایی و راندمان غذایی در طی دوره آزمایشی اندازه گیری شدند. نتایج این تحقیق نشان داد که مدل خطوط شکسته خطی برای برآورد احتیاجات لوسین جوجههای گوشتی سویه راس 308 بخوبی روی دادههای افزایش وزن، خوراک مصرفی و ضریب تبدیل غذایی برازش داده شد و میزان لوسین مورد نیاز برای این سه صفت به ترتیب 217/1، 218/1 و 213/1 درصد جیره غذایی برآورد گردید. میانگین مقادیر شاخص خونی اسید اوریک بطور معنیداری تحت تاثیر افزودن اسیدآمینه لوسین قرار گرفت (01/0>p). نتایج این آزمایش نشان میدهد که میزان احتیاجات اسیدآمینه لوسین برای حداکثر عملکرد جوجههای گوشتی بین 213/1 الی218/1 متغییر میباشد و در این بازه، مقدار اسید اوریک خون در حداقل قرار دارد. | ||

| The aim of this experiment was to determine the total leucine requirement of male Ross 308 broiler chicks. To determinate valine requirement of male broiler chicks based on growth performance, a total of 250 male broiler chicks from 24 to 39 Days of age, was assigned to 5 treatments with 5 replicate using a completely randomized design. Wheat-corn-soybean meal-based diet was formulated to provide the all nutrient except leucine, based on Ross 308 management guide. Dietary leucine was supplied in 5 levels from 1.16 to 1.36 % for the experimental period. In the experimental period weight gain, feed intake, feed conversion ratio and feed efficiency ratio were determined. Result of this study showed that the liner broken line model were used for determine of total leucine requirement for Ross 308 male broiler chicks is the well fitted base on weight gain, feed intake and feed conversion ratio, and evaluated leucine content for these performance parameters were 1.217, 1.218 and 1.213 % of diet, respectively. The result of this experiment showed that the uric acid of chickens was significantly affected by the Leucine supplementation in diet (P<0.01). The results indicated that Leucine requirement for maximum performance of broiler chicks were tolerate between 1.213 to 1.218%, and the uric acid content is lowest in this limit. | ||
