| چکیده | ||
| این پژوهش بهمنظور بررسی تاثیر پرتوهای یونساز گاما و الکترون در دزهای 25، 50 و 75 کیلوگری، بر تجزیه شکمبهای ماده خشک و پروتئین خام، و قابلیت هضم برون تنی کنجاله کانولا انجام گرفت. بدین منظور از تکنیک کیسههای نایلونی و روش هضم دو مرحلهای استفاده شد. پرتو گاما باعث کاهش تجزیهپذیری ماده خشک شد (05/0P<)، اما پرتو الکترون تاثیری بر این صفت نداشت (05/0P>). تجزیه شکمبهای پروتئین خام بهوسیله پرتوتابی کاهش یافت (05/0P<). در این خصوص تاثیر اشعه گاما بیشتر از تابش الکترون بود (05/0P<). قابلیت هضم برون تنی کنجاله کانولا تحت تاثیر پرتوتابی افزایش یافت (05/0P<). با افزایش دز تابش پرتوهای الکترون و گاما، مقدار قابلیت هضم برونتنی ماده خشک، بهطور خطی افزایش یافت (05/0P<). تاثیر تابش الکترون و اشعه گاما در افزایش این صفت یکسان بود (05/0P>). نتایج این پژوهش نشان داد که هرچند تاثیر پرتو گاما در کاهش تجزیه شکمبه ای ماده خشک و پروتئین خام کنجاله کانولا بیشتر از پرتو الکترون بود، اما قابلیت هضم برون تنی آن به طور یکسانی تحت تاثیر این پرتوهای یونساز افزایش یافت. | ||

| چکیده [English] | ||
| This research was conducted to evaluate the effects of electron beam (EB) and gamma ray (GR) radiations at doses of 25, 50 and 75 kGy on ruminal degradation kinetics of dry matter (DM) and crude protein (CP),andin vitro digestibility of canola meal (CM). The nylon bag technique and in vitro two step method were used for this aim. GR decreased ruminal degradability of DM (P<0.05), but EB had no effect on this trait (P>0.05). The ruminal degradation of CP was reduced by irradiation (P<0.05). In this case the efficacy of GR was more than EB (P<0.05). In vitro digestibility of CM was increased by irradiation (P<0.05). With increasing dose of GR and EB, the value of in vitro DM digestibility increased linearly (P<0.05). The effects of EB and GR on increasing of this trait were the same (P>0.05) The results of this study showed greater effects of GR than the EB in reducing the ruminal degradation of DM and CP, while the in vitro digestibility of CM was equally affected by these ionizing radiations. | ||
