چکیده

تاثیر انواع فرآیند کاندیشنینگ(بخار و خشک) و سطح بنتونیت سدیم فرآوری شده در خوراک بر عملکرد، وزن نسبی اندام ها و برخی فراسنجه‌های خونی در دوره رشد جوجه‌های گوشتی بررسی شد. به همین منظور از تعداد 810 قطعه جوجه خروس راس 308 در یک آزمایش فاکتوریل 3×3 با سه روش فرآوری خوراک(بدون فرآوری یا خشک، دو دقیقه فرآوری با بخار، چهار دقیقه فرآوری با بخار) و سه سطح بنتونیت سدیم فرآوری شده (جی بایند) (صفر، 75/0 و 5/1 درصد) در غالب طرح کاملاً تصادفی با نه تیمار و شش تکرار مورد آزمایش قرار گرفتند. فرآوری خوراک به تنهایی بر افزایش وزن روزانه و ضریب تبدیل خوراک تاثیر معنی‌داری داشت، بطوریکه بهترین ضریب تبدیل در دو دقیقه فرآوری با بخار(33/1) و همچنین 5/1 درصد بنتونیت سدیم(39/1) مشاهده شد(05/0>P) و این در حالی است که اثر روش فرآوری، سطح بنتونیت سدیم و اثر متقابل آنها بر مصرف خوراک معنی‌داری نبود. اثر روش فرآوری بر کلسترول و HDL خون معنی‌دار بود و اثر متقابل شکل فرآوری و سطح بنتونیت سدیم بر VLDL خون معنی‌دار بود(05/0>P) و بهترین VLDL مربوط به تیمار بدون فرآوری و بدون جی بایند بود. بجز وزن نسبی کبد، وزن نسبی هیچ کدام از قسمت‌های مختلف لاشه و اندام‌های داخلی تحت تاثیر تیمارها قرار نگرفتند.. نتایج این آزمایش نشان می‌دهند که دو دقیقه فرآوری خوراک با بخار در کارخانجات تهیه دان باعث بهبود عملکرد رشد جوجه های گوشتی در دوره رشد می‌گردد.

چکیده [English]

The impact of the conditioning process (steam and dry) and processed sodium bentonite (SB) in pellet diet on performance, carcass characteristics and some blood metabolites of broiler chickens in growing period was investigated. For this purpose, 810 day-old male broiler chickens, Ross 308 strain were used.  A completely randomized experiment in a 3×3 factorial framework with three types of feed conditionings (without conditioning (dry), 2 minutes steam-conditioning and 4 minutes steam-conditioning) and three levels of sodium bentonite as a pellet binder (0, 0.75 and 1.5 percent) in with nine treatments and six replicates was explored. Processing form alone had a significant effect on the average daily gain and feed conversion ratio(P<0.05), so that the best feed conversion ratio was observed in two minutes of the steam processing (1.33) and 1.5% of sodium bentonite (1.39). The effects of processing, the level of sodium bentonite and their interactions was not significant on feed intake. The effect of processing type on cholesterol and HDL was significant, and the interaction effects of conditioning and G-bind showed a significant effect on serum VLDL of the birds (P<0.05) and the best VLDL was related to 0 minutes steam conditioning and without G-bind. Except for the relative weight of the liver, relative weight of any of the various parts of the carcass and inner organs were not affected by treatments. In general, the 2 minutes steam improves feed conversion ratio and performance of broilers in the growing period.
