  Evolution of the density parameter in the anisotropic DGP braneworld model is
studied. The role of shear and cross-over scale in the evolution of
$\Omega_\rho$ is examined for both the branches of solution in the DGP model.
The evolution is modified significantly compared to the FRW model and further
it does not depend on the value of $\gamma$ alone. Behaviour of the
cosmological density parameter $\Omega_\rho$ is unaltered in the late universe.
The study of decceleration parameter shows that the entry of the universe into
self accelerating phase is determined by the value of shear. We also obtain an
estimate of the shear parameter $\frac{\Sigma}{H_0} \sim 1.68 \times 10^{-10}$,
which is in agreement with the constraints obtained in the literature using
data.
