چکیده

به منظور بررسی اثرات مکمل سین‌بیوتیک حاوی انتروکوکوس فاسیوم و اینولین بر عملکرد، چربی سرم خون و پاسخ های ایمنی هومورال در برابر گلبول قرمز خون گوسفند (SRBC) آزمایشی با استفاده از 400 قطعه جوجه‌های گوشتی نر انجام گرفت. جوجه ها به طور تصادفی به 16 واحد آزمایشی (25 پرنده در هر واحد) تقسیم و با جیره بر پایه ذرت و سویا تغذیه شدند. هر 4 واحد برای یک تیمار در نظر گرفته شد و مقدار صفر، 5/0، 1 و 5/1 گرم در کیلوگرم مکمل سین بیوتیک به جیره هر تیمار اضافه شد. نتایج آزمایش نشان داد که افزایش وزن و ضریب تبدیل کل دوره پرورش در تیمار 1 (به ترتیب 2662 گرم و 72/1) و 5/1 (به ترتیب 2596 گرم و 74/1) گرم سین بیوتیک در کیلوگرم جیره بیشتر از شاهد بود (05/0>P). همچنین در روز 28 و 42، میزان کلسترول سرم در تیمار 1 (به ترتیب mg/dL 8/156 و 6/107) و 5/1 (به ترتیب mg/dL3/146 و 5/106) گرم سین بیوتیک در کیلوگرم جیره کمتر از شاهد بود (05/0>P). در روز 41، عیار پادتن علیه گلبول قرمز در تیمار 1 (09/8) و تیمار 2 (69/8) گرم سین بیوتیک در کیلوگرم جیره بیشتر از شاهد بود (05/0>P). به ‌طورکلی نتایج این آزمایش نشان داد که استفاده از سطوح 1 و 5/1 گرم/کیلوگرم سین‌بیوتیک در جیره غذایی جوجه‌های گوشتی می تواند باعث بهبود عملکرد رشد، پاسخ­های ایمنی و کاهش کلسترول خون گردد.

چکیده [English]

Eexperiment was conducted to investigate the effects of a synbiotic containing Enterococcus faecium and inulin on performance, serum lipid and humoral immune response against sheep red blood cell (SRBC) with using 400 one-day-old male broiler chicks. Broiler chicks were randomly divided into 16 experimental units (25 birds per unit) and fed corn-soybean meal-based diets. Four units were considered for each treatment and 0, 0.5, 1 and 1.5 g/kg synbiotic supplement were added to diet for each treatment. The results showed that body weight gain and feed conversion ratio during the whole experimental period were higher in treatments 1 (2662g and 1.72, respectively) and 1.5 (2596 g and 1.74, respectively) g/kg synbiotic compared to control (P<0.05). Also, on 28 and 42 d, serum cholesterol levels were lower in treatments 1 (156.8 and 107.6 mg/dL, respectively) and 1.5 (146.3 and 106.5 mg/dL, respectively) g/kg synbiotic compared to control (P<0.05). On 41 d, the antibody titer against SRBC was higher in treatments 2 (8.09) and 1.5 (8.69) g/kg synbiotic in comparison with control (P<0.05). In general, the results of this experiment showed that using of 1 and 1.5 g/kg synbiotic in broiler diets could improve growth performance, immune responses and reduce serum of blood cholestrol.
