چکیده مقاله :

This study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. Two hundred and seven days old Arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (SSB); 3) basal diet + 1% non-processed sodium bentonite (SB); 4) basal diet + 1% sulphated calcium bentonite (SCB) and 5) basal diet 1% non-processed calcium bentonite (CB). Forty birds in each group were assigned to four replicates (10 birds in each). The ratio of right ventricle to total ventricles weight (RV/TV) was significantly (P

چکیده انگلیسی:

به ­منظور شناخت ارتباط عوامل فیزیولوژیک و متابولیک با بروز آسیت در جوجه‌های گوشتی آرین و همچنین بررسی اثر ترکیبات مختلف بنتونیت بر این عوامل، تعداد 200 قطعه جوجه آرین هم جنس (نر) و هم وزن در یک طرح کاملاً تصادفی مورد آزمایش قرار گرفتند. جوجه‌ها در 7 روزگی بر اساس جیره غذایی به 5 گروه آزمایشی تقسیم شدند: 1) شاهد (بدون بنتونیت)؛ 2) جیره حاوی بنتونیت سدیمی فرآوری شده با سولفات مس (1 درصد بر اساس ماده خشک)؛ 3) جیره حاوی بنتونیت سدیمی فرآوری نشده (1 درصد بر اساس ماده خشک)؛ 4) جیره حاوی بنتونیت کلسیمی فرآوری شده با سولفات مس (1 درصد بر اساس ماده خشک) و 5) جیره حاوی بنتونیت کلسیمی فرآوری نشده (1 درصد بر اساس ماده خشک). 40 قطعه جوجه در هر گروه آزمایشی به 4 تکرار 10 قطعه‌ای تقسیم شدند. (نسبت RV/TV) به عنوان مهمترین شاخص آسیت در سن 35 روزگی در گروه تغذیه شده با بنتونیت سدیمی سولفاته کمترین (24/0) بود و نسبت به گروه شاهد (29/0) تفاوت معنی ‌داری داشت (05/0P<). جیره دارای بنتونیت سدیمی سولفاته غلظت هورمون‌های T3 و T4 سرم خون نسبت به سایر جیره‌ها افزایش داد (05/0P<). درصد تلفات در گروه تغذیه شده با بنتونیت سدیمی سولفاته نسبت به گروه شاهد تمایل به کاهش داشت (10/0P<). افزودن بنتونیت به جیره به ‌ویژه از نوع سولفاته سبب کاهش شاخص آسیت و بهبود بهبود صفات مرتبط با آن شد. به طورکلی افزودن بنتونیت به جیره جوجه‌های گوشتی، اثرات مثبتی بر شاخص‌های متابولیکی و فیزیولوژیکی مرتبط با آسیت داشت که احتمالاً این اثرات را می‌توان به جذب بهتر مواد مغذی در روده نسبت داد.
