  We consider the B-ball cosmology of the MSSM in the context of D-term
inflation models where the reheating temperature is determined by the
Affleck-Dine mechanism to be of the order of 1 GeV. We show that such a low
reheating temperature can arise quite naturally as the result of a symmetry
which is required to maintain the flatness of the inflaton potential. In this
case the B-balls will decay well after the freeze-out temperature of the LSP,
allowing baryons and cold dark matter to originate primarily from B-ball
decays.
