Here we study an anisotropic model of the universe with constant energy per
particle. A decaying cosmological constant and particle production in an
adiabatic process are considered as the sources for the entropy. The
statefinder parameters $\{r,s\}$ are defined and their behaviour are analyzed
graphically in some cases.
