  We apply the dynamical large-$N$ Schwinger boson technique as an impurity
solver for the dynamical mean-field theory (DMFT) calculations of the Kondo
lattice model. Our approach captures the hybridization physics through the DMFT
self-consistency that is missing in the pure Schwinger boson calculations with
independent electron baths. The resulting thermodynamic and transport
properties are in qualitative agreement with more rigorous calculations and
give the correct crossover behavior over a wide temperature range from the
local moment regime to the Fermi liquid. Our method may be further extended to
combine with the density functional theory for efficient material calculations.
