In models of dynamical electroweak symmetry breaking which sensitivelyinvolve the third generation, such as top quark condensation, the effects ofthe new dynamics can show up experimentally in Z->b\bar{b}. We compare thesensitivity of Z->b\bar{b} and top quark production at the Tevatron to modelsof the new physics. Z->b\bar{b} is a relatively more sensitive probe to newstrongly coupled U(1) gauge bosons, while it is generally less sensitive aprobe to new physics involving color octet gauge bosons as is top quarkproduction itself. Nonetheless, to accomodate a significant excess inZ->b\bar{b} requires choosing model parameters that may be ruled out within runI(b) at the Tevatron.Comment: LaTex file, 19 pages + 2 Figs., Fermilab-Pub-94/231-
