  Kasner cosmology is a vacuum and anisotropically expanding spacetime in the
general relativity context. In this work, such a cosmological model is studied
in another context, the bumblebee model, where the Lorentz symmetry is
spontaneously broken. By using the bumblebee context it is possible to justify
the anisotropic feature of the Kasner cosmology. Thus, the origin of the
anisotropy in this cosmological model could be in the Lorentz symmetry
breaking. Lastly, an application in the pre-inflationary cosmology is
suggested.
