چکیده
دو آزمایش جهت تعیین قابلیت هضم ایلئومی مواد مغذی هسته خرمای خام و تخمیری و تأثیر آنها بر عملکرد و برخی صفات خونی در جوجههای گوشتی انجام شد. آزمایش اول در قالب طرح کاملاً تصادفی با 72 قطعه جوجه خروس گوشتی با سه تیمار و شش تکرار (چهار جوجه در هر تکرار) انجام شد. تیمارها شامل جیره پایه و دو جیره آزمایشی با جایگزینی هسته خرمای خام و تخمیری به جیره پایه با نسبت 25 درصد بودند. آزمایش دوم بهصورت فاکتوریل 4×2 با یک تیمار شاهد در قالب طرح کاملاً تصادفی با 540 قطعه جوجه یک روزه در نه تیمار و پنج تکرار (12 جوجه در هر تکرار) انجام شد. تیمارهای آزمایشی شامل جیره ذرت- سویا (شاهد)، جیرههای حاوی دو، چهار، شش و هشت درصد هسته خرمای خام و یا هسته خرمای تخمیری بود. قابلیت هضم فیبرخام، پروتئین خام و خاکسترخام در هسته خرمای تخمیری بیشتر از هسته خرمای خام بود (p<0/05). تغذیه با هسته خرمای تخمیری در مقایسه با هسته خرمای خام، باعث بهبود افزایش وزن (2110/5 گرم در برابر 1991/3 گرم) و افزایش مصرف خوراک شد (p<0/05). غلظت کلسترول و LDL-c سرم خون در جوجههای تغذیهشده با هسته خرمای تخمیری کمتر از جوجههای تغذیهشده با هسته خرمای خام بود (p<0/05). با توجه به نتایج این تحقیق، تخمیر هسته خرما موجب افزایش قابلیت هضم مواد مغذی آن و بهبود افزایش وزن جوجه های گوشتی میشود.

چکیده [English]
Two experiments were conducted to determine the nutrient ileal digestibility of raw date pit (RDP) and fermented date pit (FDP) as well as their effects on performance and some bloody traits in broiler chickens,. The first experiment was conducted in a completely randomized design with 72 male broiler chicks, three treatments and six replicates (four chicks each) . The treatments consisted of a corn – soybean diet and two experimental diets which prepared by replacing RDP and FDP to basal diet at 25 %. The second experiment was performed in a 2× 4 factorial arrangement along with a control treatment in completely randomized design in a population of 540 day old broiler chickens in nine treatments with five replicates (12 chicks each). Dietary treatments included a diet without date pit (control), and diets containing two, four, six and eight percent of RDP or FDP. The digestibility of crude protein, fiber and ash in the FDP were higher than RDP (p<0.05). Feeding broiler chickens with FDP compared to RDP, improved weight gain (2110.5 g vs 1991.3 g ) and increased feed intake (p<0.05). The blood cholesterol and LDL-c decreased in chickens fed by FDP compared to RDP (p<0.05). According to the results of this experiment fermentation of date pit increases digestibility of its nutrients and improves weight gain of broiler chickens.
