We calculate the effective thermal conductivity {kappa}{sub {ital e}{ital f}{ital f}} in the superfluid phase of {sup 3}He-{sup 4}He mixtures below {ital T}{sub {lambda}} within the nonasymptotic field-theoretic version of the model of Siggia and Nelson. The nonuniversal parameters appearing in statics and dynamics are taken from an analysis above {ital T}{sub {lambda}}. The temperature-independent values of {kappa}{sub {ital e}{ital f}{ital f}} for the concentrations analyzed (0.1%--37%) are in agreement with experiment.
