| چکیده | ||
| این آزمایش، با تعداد 700 جوجه بلدرچین ژاپنی به منظور بررسی اثر مکمل‌‌سازی سطوح مختلف پودر ژل آلوئهورا (صفر، 1/0، 2/0 و 3/0 درصد از جیره) بر عملکرد، وزن اندامهای گوارشی و میکروفلور روده جوجههای گوشتی در قالب یک طرح کاملا" تصادفی با 4 تیمار، 5 تکرار و 35 پرنده (بهصورت مخلوط نر و ماده) در هر تکرار به مدت 6 هفته (1 الی 42 روزگی) انجام شد. خوراک مصرفی، افزایش وزن و ضریب تبدیل خوراک جوجه بلدرچین به صورت دوره‌‌ای (آغازین: 1 تا 21 روزگی، رشد: 22 تا 42 روزگی و کل دوره پرورش: 1 تا 42 روزگی) مورد بررسی قرار گرفت. میکروفلور روده‌‌ای با استفاده از کشت محتویات ایلیوم در محیطهای ائوزین متیلن بلو، MRS Agar و نوترینت آگار در پایان دوره پرورش بررسی شد. خوراک مصرفی، افزایش وزن و ضریب تبدیل خوراک جوجه بلدرچین‌‌ها در دورههای مختلف تحت تأثیر سطوح مصرفی پودر ژل آلوئهورا قرار نگرفتند (05/0<P). با وجود تفاوت مشاهده شده در مورد وزن نسبی دئودنوم بین تیمار شاهد در مقایسه با تیمارهای 1/0 و 2/0 درصد پودر ژل آلوئهورا (05/0P<)، وزن ژژنوم و ایلیوم در بین تیمارها تفاوت معنیداری را نشان نداد (05/0<P). با افزایش سطح مصرف پودر ژل آلوئهورا، تعداد باکتریهای لاکتوباسیلوس افزایش یافت به طوری که تفاوت بین تیمار 3/0 درصد پودر ژل آلوئهورا با تیمار شاهد در این خصوص معنیدار بود (05/0P<). تعداد باکتریهای اشرشیاکلی با افزایش سطح مصرف آلوئه ورا کمتر شد هرچند تفاوت از نظر آماری معنیدار نبود (05/0<P). بنابراین و با توجه به مؤثر بودن پودر ژل آلوئه ورا در ارتقاء میکروفلور مفید روده‌‌ای و نیز کاهش تعداد میکروبهای مضر، استفاده از این ترکیب فایتوبیوتیکی جهت کنترل تعادل میکروبی دستگاه گوارش و ارتقاء سلامت جوجه بلدرچین ها توصیه میشود | ||

| چکیده [English] | ||
| This study was conducted in order to evaluate the effects of dietary Aloe vera gel powder on performance, gastrointestinal organs and intestinal microflora in Japanese quails. Seven hundred one day old Japanese quails were allocated in a completely randomized design with 4 treatments replicated 5 times each with 35 birds per replicate for 6 weeks. The experimental treatments were: 1) control group (basal diet, diet without aloe vera gel powder), 2) basal diet + 0.1 percent of aloe vera gel powder. 3) basal diet + 0.2 percent of aloe vera gel powder, and 4) basal diet + 0.3 percent of aloe vera gel powder. The bacteria populations of the intestinal tract were investigated using eosin methylene blue, MRS agar and agar nutrient media. The results did not show any significant differences between dietary treatments for feed intake, feed conversion ratio and weight gain (P>0.05). There were also no significant differences between the dietary treatments for the relative weight of thigh, gizzard and liver (P>0.05). For duodenal weight, there were significant differences between control group and treatments supplemented with 0.2 and 0.3 % of Aloe vera gel powder (P<0.05). However, threre were not significant differences between the dietary treatments for the relative weights of jejunum and ileum (P>0.05). In spite of non-effective impact of Aloe vera gel powder on the performance of the quails, the results indicated a beneficial effect for Aloe vera gel powder on gut microflora by decreasing and increasing the counts of E-Coli and lactobacillus, respectively. Therefore, adding Aloe vera gel powder to the diets of Japanese quails could be recommended in order to controlling the gut microflora communities and enhancing the health status. | ||
