We present a comparative analysis of the non-perturbative intrinsic charm quark contribution in the proton, using the inclusive production of $\gamma +c $-jet in $ pp $ and $ p\bar{p} $ collisions and for the kinematic regions that are sensitive to this contribution. We discuss the $ Q^2 $ evolution of intrinsic quark distributions and present a code that provide these distributions as a function of $ x $ and $ Q^2 $ for any arbitrary momentum fraction. For the $ p\bar{p} $ collisions at the Tevatron, the results are compared with the recent experimental data of D0 at $ \sqrt{s} =1.96$ TeV and also predictions for $ pp $ collisions at $ \sqrt{s} =8$ TeV and $ \sqrt{s} =13$ TeV for the LHC.
