In this paper, we investigate the conservation laws of different types of particles in theories with a universal gravity/matter coupling. The result brings new insight about previous studies on universal gravity/matter theories. Especially, the paper demonstrates that, for perfect fluids, there is an equivalence between the assumption L-m = -is an element of, where is an element of is the total energy density, and the assumption that the matter fluid current is conserved [del(sigma)(rho u(sigma)) = 0, where rho is the rest mass density]. However, the main result is given in the general case in which one does not make any assumption on the conservation of the matter fluid current.
