Thermal conductivity measurements were performed on single crystal samples of the superconducting filled-skutterudite compounds PrOs4Sb12 and PrRu4Sb12 both as a function temperature transverse magnetic field. In zero field, low electronic thermal is consistent with fully gapped Fermi surface. For PrOs4Sb12, residual conduction in zero-temperature limit presence nodes energy gap. The for shows rapid rise at fields. PrRu4Sb12, this interpreted terms multiband effects. we consider Doppler shift nodal quasiparticles
