We consider a class of technicolor models in which techni-vector mesons are incorporated in analogy to vector-meson dominance in QCD. Modifications to standard-model results on {ital W}- and {ital Z}-boson properties are used to constrain some of the technicolor parameters. We also point out that even in the presence of a custodial symmetry, the relationship {ital M}{sub {ital W}}{sup 2}/{ital M}{sub {ital Z}}{sup 2} cos{theta}=1 is modified while the {rho} parameter defined in terms of the neutral-to-charged-current ratio is not.
