  In this paper we study a H\'enon-like equation (see equations (1) below),
where the nonlinearity f(t) is not homogeneous (i.e., it is not a power). By
minimization on the Nehari manifold, we prove that for large values of the
parameter $\alpha$ there is a breaking of symmetry and non radial solutions
appears. This holds for sub- and super-critical growth of the nonlinearity f.
