  We discuss three manners to implement Lorentz symmetry breaking in a
superfield theory formulated within the superfield formalism, that is,
deformation of the supersymmetry algebra, introducing of an extra superfield
whose components can depend on Lorentz-violating (LV) vectors (tensors), and
adding of new terms proportional to LV vectors (tensors) to the superfield
action. We illustrate these methodologies with examples of quantum
calculations.
