چکیده

تأثیر استفاده از غلاف بادام‌زمینی به عنوان یک منبع فیبر نامحلول در جیره بر عملکرد رشد، ریخت‌شناسی روده و قابلیت هضم مواد مغذی با استفاده از 320 قطعه جوجه گوشتی سویه راس 308 در قالب طرح کاملاً تصادفی با چهار تیمار (سطوح صفر (شاهد)، 5/2، 5 و 5/7 درصد غلاف بادام‌زمینی در جیره) 5 تکرار و 16 پرنده در هر تکرار از سن 11 تا 42 روزگی بررسی شد. در دوره رشد (11 تا 24 روزگی)، استفاده از غلاف بادام‌زمینی در جیره، مصرف خوراک و ضریب تبدیل غذایی را کاهش داد، ولی پرندگانی که با جیره حاوی 5/7 درصد غلاف بادام‌زمینی تغذیه شدند، افزایش وزن روزانه بیشتری داشتند (05/0> P). غلاف بادام‌زمینی، ضرایب قابلیت هضم ماده خشک و عصاره اتری را بهبود بخشید و جیره­های حاوی سطوح 5/2 یا 5 درصد غلاف بادام‌زمینی قابلیت هضم ماده آلی بالاتری در مقایسه با جیره شاهد داشتند (05/0> P). طول پرزهای روده کوچک جوجه­های تغذیه شده با جیره­های حاوی 5 یا 5/7 درصد غلاف بادام‌زمینی در مقایسه با پرنده­های شاهد بیشتر بود (05/0> P). نتایج تحقیق حاضر نشان داد که استفاده از غلاف بادام‌زمینی تا سطح 5/7 درصد از جیره اثری منفی بر عملکرد رشد جوجه­های گوشتی ندارد.

چکیده [English]

The effect of peanut pod as insoluble fiber source in diets on growth performance, small intestine morphology and nutrient digestibility of broilers was evaluated. This study was conducted using 320 Ross-308 broiler chickens in a completely randomized design with four treatments diets (containing 0 (control), 2.5, five or 7.5 percent peanut pod), with five replicates and 16 birds in each from 11 to 42 days of age. At the growth phase (11 to 24 d) dietary peanut pod decreased feed intake and feed conversion ratio, however, the birds that fed the diet containing 7.5 percent had higher daily weight gain (P<0.05). Peanut pod improved the digestibility coefficients of dry matter and ether extract and the diets containing 2.5 or 5.0 percent peanut pod had more organic matter digestibility than the control diet (P<0.05) Chicks that fed the diets containing 5.0 or 7.5 percent peanut pod, the villous was (P<0.05) longer than control birds. The results of present study suggest that using peanut pod up to 7.5 percent of diet did not adversely affect chickens growth performance and can improve feed conversion ratio at the grower phase.
