Abstract :

هدف از این مطالعه ارزیابی بهترین سطحی از وارد کردن کاکتوس گلابی در سیلو کردن دانه‌های علوفه فیل برزیلی (BRS) capiacu (Pennisetum purpureum)، آثار آن روی ویژگی‌های تخمیری، و ارزش غذایی بود. تیمارهای آزمایشی شامل سیلاژ علوفه BRS capiacu با پنج سطح از وارد کردن کاکتوس گلابی (0، 5، 10، 15 و 20 درصد گنجانده شده به عنوان پایه تازه) در طول سیلوکردن بود. یک طرح کاملاً تصادفی با پنج تیمار و شش تکرار استفاده شد. گنجاندن کاکتوس گلابی در سیلاژ علوفه BRS capiacu مقدار pH حجم سیلو شده را تغییر نداد (P=0.18)، با میانگین 3.8. تنوع حاشیه‌ای بین بالاترین دز کاکتوس گلابی گنجانده شده و گروه کنترل (بدون کاکتوس گلابی) برای پساب (effluent) 50.33 درصد، با میانگین 1.06 درصد برای هر واحد درصد از کاکتوس گلابی گنجانده شده بود. محتوی خاکستر (P=0.79)، کل کربوهیدارت‌های (P=0.30)، کل مواد غذایی قابل هضم (P=0.79)، پروتئین محلول در شوینده خنثی (P=0.66) و عصاره اتر (P=0.42) با گنجاندن کاکتوس گلابی تغییر نکرد، میانگین‌ها به ترتیب 8.01، 2.53، 3.14، 11.74، 80.88 و 44.69 درصد بود. قابیلت هضم in vitro ماده خشک (0.01>P) و فیبر شوینده در محلول خنثی (0.01>P) به‌ طور خطی با گنجاندن کاکتوس گلابی افزایش یافت. گنجاندن تا 5 درصد کاکتوس گلابی در سیلاژ علوفه BRS capiacu ویژگی‌های تخمیری و ارزش غذایی سیلاژ را بهبود می‌دهد.
