The metallic phase of the two-orbital Anderson lattice is studied in the limit of infinite spatial dimensions, where a second-order perturbation treatment is used to solve the single-site problem. Using this approximation, in the Kondo regime, we find that the finite-temperature properties of the conduction electrons exhibit the same behaviour as is observed in the metallic phase of the two-channel Kondo lattice. Possible connections between these two models are discussed.
