Following a paper by Berman and Marinho Jr (2001), where it was established an equation of state (p=-(1/3)rho), for the very early Universe, under which, Einstein's equations with lambda=0, render a scale-factor proportional to the time coordinate, and under which, Berman(2006, 2006a) showed that in the non-null lambda case, the Universe entered automatically into an exponential inflationary phase, we now study the corresponding effect in Brans-Dicke Cosmology. We find that the resulting models are similar to those in General Relativity Cosmology.
