New strong gauge interactions remain a viable source for the electroweak symmetry breaking. However, addressing the generation of fermion masses remains a challenge. A basic observable which provides stringent constraints on the flavor extensions of Technicolor-type models is the decay rate of the Z boson into a bbbar-pair. In this paper we provide a general framework to evaluate the resulting constraints on the technicolor theory level taking into account the contributions from the vector and axial vector mesons and discuss the consequences for phenomenology.
