چکیده مقاله :
The objective of this study was to evaluate the best level of inclusion of cactus pear in the ensiling of elephant grass Brazil seeds (BRS) capiaçu (Pennisetum purpureum), its effects on fermentative characteristics; and nutritional value. Experimental treatments consisted of BRS capiaçu grass silage with five levels of inclusion of cactus pear (0, 5, 10, 15 and 20% inclusion as fresh basis) during ensiling. A completely randomized design with five treatments and six replicates was used. The inclusion of cactus pear in BRS capiaçu grass silage did not alter the pH of the ensiled mass (P=0.18), mean of 3.8. The marginal variation between the highest cactus pear inclusion dose and the control group (without cactus pear) for effluent was 50.33%, mean of 1.06% for each percentage unit of cactus pear inclusion. The ash content (P=0.79), total carbohydrates (P=0.30), total digestible nutrients (P=0.79), neutral detergent insoluble protein (P=0.66) and ether extract (P=0.42) did not change with the inclusion of cactus pear, being the averages of 8.01, 2.53, 3.14, 11.74, 80.88 and 44.69%, respectively. In vitro digestibility of dry matter (p <0.01) and neutral detergent fiber (p <0.01) increased linearly with the inclusion of cactus pear. The inclusion of up to 5% of cactus pear in silage BRS capiaçu grass improves the fermentation characteristics and the nutritional value of silage.
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.
