A fundamental weak-field test of a theory of gravitation is that it satisfies the Parametrized Post-Newtonian (PPN) parameters determined by solar system experiments. The production of primordial helium and deuterium in the big bang is a test of a gravitational theory in the strong-field approximation, and we suggest its use along with the PPN parameters. We apply this test to Rosen's bi-metric theory of gravitation. For a wide class of models of this theory we show that essentially no primordial helium or deuterium is produced.
