چکیده

به ‌منظور تعیین نیاز روی جوجه های گوشتی در شرایط تغذیه با جیره های بر پایه گندم آزمایشی با استفاده از 250 قطعه جوجه گوشتی یک روزه سویه راس 308 در قالب طرح کاملاً تصادفی با پنج تیمار، پنج تکرار و 10 قطعه جوجه در هر تکرار در دوره سنی یک تا 42 روزگی انجام شد. تیمارهای آزمایشی شامل تأمین پنج سطح غلظت روی جیره (30، 70، 110، 150 و 190 میلیگرم در کیلوگرم) با افزودن مکمل روی به فرم "ZnSO4.7H2O" بودند. با افزایش سطح روی جیره به 70 میلیگرم در کیلوگرم شاخصهای عملکردی شامل میانگین وزن در سنین، 10، 24 و 42 روزگی، مصرف خوراک و رشد روزانه در دوره های سنی یک تا 10، 42-25 و یک تا 42 روزگی و بازده غذایی در دوره سنی یک تا 10 روزگی به‌طور معنی دار افزایش یافتند. میزان احتیاجات روی به ‌منظور بهینه سازی شاخصهای میانگین وزن پایان دوره پرورش، مصرف خوراک، افزایش وزن روزانه و بازده غذایی با استفاده از مدل رگرسیونی خط شکسته خطی به ترتیب 68.77، 83.12، 66.99 و 62.75 میلیگرم در کیلوگرم جیره و با استفاده از مدل رگرسیونی خط شکسته درجه ‌دو به ترتیب 70.00، 79.93، 69.63 و 58.01 میلیگرم در کیلوگرم جیره برآورد شد. با توجه به نتایج این تحقیق احتیاجات روی جوجه های گوشتی در شرایط تغذیه با جیره های بر پایه گندم به ‌منظور بروز بهینه شاخصهای عملکرد رشد در دامنه 83-58 میلیگرم در کیلوگرم جیره، بیشتر از توصیه انجمن ملی تحقیقات و کمتر از توصیه سویه های تجاری است.

چکیده [English]

The present study was conducted to determine the zinc (Zn) requirement in broiler chickens fed wheat-soy based diet. Two hundred fifty day-old broiler chicks (Ross 308), were randomly assigned to a completely randomised design (CRD) experiment with 5 treatments, and 5 replicates of 10b each. The experimental treatments included five dietary Zn levels (30, 70, 110, 150, and 190 mg/kg) provided by the addition of reagent grade “ZnSO4.7H2O”. The experiment lasted from 1-42d of age. Increasing dietary Zn level to 70mg/kg significantly increased 10, 24 and 42d live body weight (LBW), feed intake (FI) and weight gain (WG) during 1-10, 25-42 and 1-42d of age and feed efficiency (FE) during 1-10d of age. The linear broken-line (LBL), quadratic-broken line (QBL) and the quadratic polynomial (QP) regression models were used to estimate the Zn requirement. The Zn requirement for optimal final LBW and FI, WG, and FE during 1-42d of ages by LBL model were 68.77, 83.12, 66.99 and 62.75 mg/kg of diet, and by QBL model 70.00, 79.93, 69.63 and 58.01 mg/kg of diet, respectively. In conclusion, Zn requirement varied between 58-83 mg/kg, which is higher than NRC and is lower than strain recommendation in the broiler chickens fed wheat-based diet.
