بررسي اثرات مخلوط عصاره گياهان دارويي بر اجزا لاشه و پاسخ ايمني جوجه گوشتي

Evaluating the effects of medicinal plant extract mixture on carcass traits and immune response of broilers

اين آزمايش به منظور بررسي اثرات مخلوط عصاره 5 گياه دارويي بر اجزا لاشه و پاسخ ايمني جوجه گوشتي انجام گرديد. بدين منظور از 350 قطعه جوجه‌خروس يك روزه نژاد راس 308 در يك طرح كاملاً تصادفي با 7 تيمار و 5 تكرار و 10پرنده در هر تكرار به مدت 42 روز استفاده شد. تيمارهاي آزمايشي به منظور بررسي و مقايسه تركيبي عصاره هاي گياهي پونه كوهي، نعنا فلفلي، آويشن، رزماري، رازيانه و زردچوبه دسته بندي شدند و به ميزان 600 ميلي گرم به ازاي هر كيلوگرم خوراك به جيره افزوده گرديد. در سن35 روزگي از هر تكرار يك پرنده انتخاب و خونگيري به عمل آمد و تيتر نيوكاسل و آنفولانزا به روش HI محاسبه گرديد. در پايان آزمايش از هر تكرار يك قطعه پرنده كشتار و اجزا لاشه آن توزين و وزن نسبي آن‌ها تعيين گرديد. نتايج آزمايش نشان داد افزودن مخلوط عصاره هاي گياهي به جيره ي جوجه هاي گوشتي تاثير معني داري بر وزن نسبي اجزا لاشه و پاسخ ايمني عليه نيوكاسل و آنفولانزآ در مقايسه با تيمار شاهد نداشت.

This experiment was conducted in order to investigate the effects of 5 medicinal plant extract mixture on carcass components and the immune response in broiler chickens. For this purpose, 350 one-day-old of Ross 308 broilers were used in a completely randomized design with 7 treatments and 5 replications and 10 birds per replication for 42 days. In order to investigate and compare the experimental treatments, plant extracts of oregano, peppermint, thyme, rosemary, fennel and turmeric were grouped and added to the diet at the rate of 600 mg per kilogram of feed. At the age of 35 days, one bird from each replicate was selected and blood was taken. The Newcastle and influenza titers were determined by the HI method. At the end of the experiment, one bird from each replicate were slaughtered and its carcass components were weighed and their relative weight was determined. The results of the experiment showed that adding a mixture of plant extracts to the diet of broiler chickens did not have a significant effect on the relative weight of the carcass components and the immune response against Newcastle disease and influenza compared to the control treatment.
