چکیده

این آزمایش به منظور مطالعه اثر کاهش و یا حذف مکمل ویتامینی از جیره­ پایانی برپایهگندم بر شاخص­های عملکردی، راندمان لاشه، خاکستر استخوان درشت نی و پاسخ ایمنی همورالدر جوجه­های گوشتی با استفاده از 350 قطعه جوجه خروس گوشتی راس 308 در قالب طرح کامل تصادفی با هفت تیمار، پنج تکرار و 10 قطعه پرنده در هر تکرار انجام شد. تیمار­های آزمایشی شامل: تیمار یک (شاهد)؛ تغذیه با جیره­ی بر پایه گندم حاوی 5/2 گرم بر کیلوگرم مکمل ویتامینی در کل دوره پرورش، تیمارهای دو، سه و چهار؛ کاهش سطح مکمل ویتامینی جیره­ به 25/1 گرم بر کیلوگرم به ترتیب از سنین 25، 31 و 37 روزگی و تیمارهای پنج و شش و هفت؛ حذف کامل مکمل ویتامینی جیره­ به ترتیب از سنین 25، 31 و 37 روزگی بودند. نتایج نشان داد؛ کاهش سطح مکمل ویتامینیجیره به 25/1 گرم بر کیلوگرم از سن 25 روزگی تأثیر معنی­داری بر شاخص­های عملکردی نداشت. حذف کامل مکمل ویتامینی جیره از سن 25 روزگی باعث کاهش معنی­دار (05/0P<) شاخص­های عملکردی شد. راندمان لاشه، خاکستر استخوان درشت­نی و پاسخ ایمنی همورال جوجه­های گوشتی علیه تزریق گلبول­های قرمز گوسفندی تحت تأثیر کاهش و یا حذف کامل مکمل ویتامینی جیره از سنین مختلف (25، 31 و 37 روزگی) قرار نگرفتند. نتیجه­گیری می­شود که امکان کاهشسطحمکملویتامینی در جیره پایانی بر پایه گندم جوجه­های گوشتی وجوددارد.

چکیده [English]

This experiment was carried out to study the effect of vitamin premix (VP) reduce/withdraw of finisher wheat based diet on growth performance, carcass efficiency, tibia bone ash, and humoral immune response of broiler chickens. Three hundred and fifty, one day-old male broiler chicks (Ross 308) were used in a complete randomized design (CRD) experiment with 7 treatments of 5 replicates and 10 birds each. The dietary treatments were: T1 (control), fed the basal diet containing 2.5g VP/kg of diet; T2, T3 and T4, The reduce dietary VP levels to 1.25 g/kg of diet from 25, 31 and 37 day of ages respectively; T5, T6 and T7, The complete withdrawal dietary VP from 25, 31 and 37 day of ages respectively. The results showed; reduced dietary VP levels to 1.25g/kg of diet from 25d of age did not impair effects on growth performance. The complete withdrawal dietary VP from 25d significantly decreased growth performance (P<0.05). The reduced/ withdraw dietary VP levels from 25, 31 and 37 day of ages had not significant effects on carcass efficiency, tibia bone ash, and humoral immune response to SRBC injection. It is concluded that it is possible to reduce the vitamin supplements in finisher broiler wheat based diets.
