We study the analytic Bethe, ansatz in solvable vertex models associated with the YangianY(Xr) or its quantum affine analogueUq(Xr(1)) forXr=Br,CrandDr. Eigenvalue formulas are proposed for the transfer matrices related to all the fundamental representations ofY(Xr). Under the Bethe ansatz equation, we explicitly prove that they are pole-free, a crucial property in the ansatz. Conjectures are also given on higher representation cases by applying theT-system, the transfer matrix functional relations proposed recently. The eigenvalues are neatly described in terms of Yangian analogues of the semi-standard Young tableaux.
