چکیده
اثر اسیدی‌کننده‌های خوراکی گلوباسید ، گرین‌کب و استفاده‌ی همزمان آنها بر عملکرد ، خصوصیات لاشه، گوارش‌پذیری مواد مغذی و جمعیت میکروبی ایلئوم جوجه‌های گوشتی با استفاده از 128 قطعه جوجه‌ی گوشتی یک روزه سویه تجاری کاب 500 مخلوط هر دو جنس در قالب طرح کاملا تصادفی با چهار تیمار، چهار تکرار و هشت قطعه پرنده در هر تکرار بررسی شد. تیمارهای آزمایشی شامل جیره‌ی شاهد، جیره‌ی شاهد+ 085/0 درصد گلوباسید، جیره‌ی شاهد + 035/0 درصد گرین‌کب و جیره‌ی شاهد+ 085/0 درصد گلوباسید+ 035/0درصد گرین‌کب بودند. تیمارهای آزمایشی بر عملکرد، خصوصیات لاشه و جمعیت میکروبی معنی دار نبود و بیشترین مقدار گوارش‌پذیری ظاهری ماده‌ی خشک، ماده‌ی آلی و پروتئین در تیمار حاوی مخلوط دو نوع اسیدی کننده‌ی گرین کب و گلوباسید در مقایسه با تیمار شاهد مشاهده شد. بر اساس نتایج این مطالعه، استفاده از مخلوط اسیدی‌کننده‌های گرین کب و گلوباسید می تواند با بهبود گوارش‌پذیری ماده‌ی خشک، ماده‌ی آلی و پروتئین خام و تا حدودی کم کردن مصرف خوراک برای جوجه های گوشتی مفید باشد.

Effect of two types of dietary acidifiers on nutrient digestibilities, ileum microflora and growth performance in broilers
چکیده [English]
The effect of two types of dietary acidifier; Globacid®, Greencab® and their mixture on growth performance, carcass characteristics, nutrient digestibilities and intestinal microflora in broilers were studied by using hundred and twenty eight one-day old Cobb 500 broiler chickens of either sex, four treatments and four replicates of eight chicks in each in a completely randomized disign. The experimental treatments consisted of a basal diet; diet containing basal diet + 0.085 percent Globacid®; diet containing basal diet + 0.035 percent Greencab® and diet containing basal diet + mixture of 0.085 percent Globacid® and 0.035 percent Greencab®. The effect of treatments on growth performance, carcass characteristics and intestinal microflora was not significant and the higher digestibility of dry matter, organic matter and crude protein in comparison to control diet were seen in treatment containing the mixture of Globacid® and Greencan® acidifiers. According to the results of this study, the dietary mixture of Globacid® and Greencan® acidifiers can be useful in broilers by improving dry matter, organic matter and crude protein digestibilities and decreasing feed intake trend.
