چکیده

 این آزمایش با هدف مقایسه اثر کنجاله­ کنجد خام و فرآوری شده به ­روش تخمیر حالت جامد  بر خصوصیات استخوان درشت نی و برخی فراسنجه­ های خون انجام شد. تخمیر کنجاله کنجد با کشت مخلوط مایع حاوی لاکتوباسیلوس پلانتاروم در نسبت 1 به 1/2 انجام شد. پس از 28 روز تخمیر، میزان اسید فایتیک و تانن به ­ترتیب از 17/39 و 15/26 به 5/26 و 2/22 میلی­ گرم در گرم کنجاله کاهش یافت. تعداد 315 قطعه جوجه گوشتی راس 308 در قالب طرح کاملاً تصادفی با 7 تیمار آزمایشی و 3 تکرار اختصاص یافت. تیمارهای آزمایش شامل جایگزینی 25، 50 و 75 درصد کنجاله کنجد خام یا تخمیری با کنجاله سویا (تیمار شاهد) در جیره بودند. نتایج این آزمایش نشان داد استفاده از سطوح 25 و 50 درصد کنجاله کنجد تخمیری، مشابه با تیمار شاهد، افزایش میزان خاکستر، کلسیم و فسفر استخوان درشت نی جوجه­ های گوشتی را نسبت به کنجاله کنجد خام بهبود داد (0/05>P). هم­ چنین میزان کلسیم و فسفر خون در تیمارهای حاوی کنجاله کنجد تخمیر شده نسبت به سایر تیمارها افزایش معنی­ داری یافت (0/05>P).

چکیده [English]

This experiment was conducted for Comparison the effects of raw and fermented sesame meal by solid state fermentation on tibia bone characteristics and some blood parameters of broiler chickens. Raw sesame meal was fermented with the liquid mixed culture containing Lactobacillus plantarum in the ratio of 1:1.2. After 28-day fermentation phytic acid and tannin were reduced from 17.39 and 15/26 to 5.26 and 2/22 mg/g, respectively. A total of 315 Ross-308 broilers in a completely randomized design were allocated to 7 treatments with 3 replicates. Experimental treatments were containing 25, 50 and 75% raw or/and fermented sesame meal replaced by soybean meal in diets. The results of this experiment showed that the use of 25 and 50% levels of fermented sesame meal, similar to the control treatment, improved the amount of ash, calcium, and phosphorus in tibia bone of broiler chicken (P<0.05). The amount of calcium and phosphorus in the blood treatments containing fermented sesame meal compared to other treatments significantly increased (P<0.05)
