AB  - The aim of this study was to evaluate the effects of gamma irradiation (&#947;-irradiation) at doses of 15, 30 and 45 kGy on antinutritional factors, <I>in vitro</I> CP digestibility, ruminal Dry Matter (DM) and Crude Protein (CP) degradibility of Canola Meal (CM). Three ruminally fistulated Gezel rams were used to measure ruminal <I>in situ</I> Dry Matter (DM) and CP degradability. The chemical composition of raw and irradiated CM was similar. Results showed that phytic acid in &#947;-irradiated CM at dose of 15, 30 and 45 kGy &#947;-irradiated CS decreased (p&lt;0.01) by 26.2, 51 and 56.7%, respectively. Total glucosinolate contents of 15, 30 and 45 kGy &#947;-irradiated CM was decreased (p&lt;0.01) 26.3, 51 and 63.4%, respectively. From <I>in sacco</I> results, &#947;-irradiation decreased (p&lt;0.05) the washout fractions of CP at doses of 30 and 45 kGy. Gamma irradiation also reduced (p&lt;0.05) degradation rate of the b fraction of CP so at doses of 30 and 45 kGy, Effective Degradibility (ED) of CP (rumen outflow rate of 0.05 h<SUP>-1</SUP>) were decreased by 8.2 and 21.0%, Compared to untreated sample. On the contrary digestibility of ruminally undegraded CP of irradiated CM at doses of 30 and 45 kGy was improved (p&lt;0.05) by 10.6 and 15.5%.
