We examine one-loop vertex corrections to the process {ital Z}{r arrow}{ital b{bar b}} in the minimal supersymmetric standard model. The amplitude for this process may be enhanced by large Yukawa couplings which arise in the case of a heavy top or a very large value of tan{beta}. This leads to the possibility that supersymmetry might be observed indirectly by precision measurements of {ital B}({ital Z}{r arrow}{ital b{bar b}}).
