چکیده

این آزمایش با هدف بررسی تأثیر افزودن پودر اِکلیل کوهی (Rosmarinus officinalis) به همراه روغن کنجد و سویا بر تغییرات ریخت­  شناسی روده، کیفیت گوشت و برخی از شاخص ­های خونی در بلدرچین ژاپنی طراحی شد. این آزمایش به‌صورت فاکتوریل در قالب طرح کاملاً تصادفی  با 6 تیمار،4 تکرار و در هر تکرار 15 قطعه بلدرچین گوشتی به اجرا درآمد. تیمارهای آزمایشی شامل: 1) روغن کنجد + سطح صفر اِکلیل کوهی  2) روغن کنجد + سطح یک اِکلیل کوهی  3) روغن کنجد + سطح دو اِکلیل کوهی  4) روغن سویا + سطح صفر اِکلیل کوهی  5) روغن سویا + سطح یک اِکلیل کوهی  6) روغن سویا + سطح دو اِکلیل کوهی. در روز 35 انجام آزمایش از هر پن دو عدد بلدرچین (نر و ماده) نزدیک به میانگین وزنی جمعیت انتخاب گردید هر بلدرچین به صورت دستی پوست کنده و تفکیک لاشه و توزین شد. نتایج نشان داد که تفاوت معنی ­داری بین تیمارهای آزمایشی برای وزن سر، وزن ران، وزن پانکراس، وزن قلب، وزن سنگدان و وزن بیضه وجود نداشت. اما اثر روغن کنجد بر صفات مذکور بیش تر از روغن سویا بود (0/05>P). در فراسنجه‌های خونی، میزان اوره با افزایش سطح اکلیل کوهی به طور معنی داری کاهش یافت (0/05>P). تفاوتی بین pH گوشت در بین گروه آزمایشی متفاوت نبود. شاخص تیوباربیتوریک اسید (TBA) در بین تیمارهای آزمایشی (سطوح روغن) اختلاف معنی‌دار وجود داشت (0/05>P). در شاخص افت ناشی از پخت اختلاف معنی‌داری بین تیمارهای آزمایشی نبود. در شاخص افت ناشی خونابه در بین تیمارهای آزمایشی تفاوت معنی‌داری وجود نداشت. استفاده از پودر اِکلیل کوهی به همراه روغن کنجد در جیره، سبب بهبود صفات لاشه شد.

چکیده [English]

The experiment was designed to investigate the effect of adding rosemary powder (Rosmarinus officinalis) along with sesame and soybean oil on changes in intestinal morphology, meat quality and some blood indices in the Japanese quail. The experiment was performed in factorial based on completely randomized design with 6 treatments, 4 replications and 15 meat quail pieces in each repetition. Experimental treatments include: 1) Sesame oil + zero surface of rosemary 2) Sesame oil + 1 g/kg rosemary 3) Sesame oil + 2 g/kg rosemary 4) Soybean oil + zero level of rosemary 5) Soybean oil + level one of rosemary 6 ) Soybean oil + level two rosemary. On the final 35 day of the experiment, two quails (male and female) were selected from each pen that weighed close to the average weight of the population. Each quail was manually peeled and carcasses separately, and different parts of the body were weighed and internal organs were weighed. The results showed that head, thigh, pancreatic, heart, gingival and testicular relative weight were not significantly different in experimental treatments (P <0.05). But the effect of sesame oil was more than soybean oil (P<0.05). In blood indices, urea levels were significantly reduced with increasing rosemary powder levels (P<0.05).Meat pH did not differ between the experimental group. Beyond the TBA, there was a significant difference between the experimental treatments (p<0.05). TBA decreased with increasing amount of Rosemary powder. In cookingloss, there was no significant difference between the experimental treatments. In drippingloss, there was no significant difference between experimental treatments. As a result, the use of Rosemary powder and sesame oil in  diet can have positive and beneficial effects on quail.
