The factorizable W-exchange contribution to $\\bar B^0\\to\\Lambda_c\\bar p$ is negligible. Applying the bag model to evaluate the baryon-to-baryon weak transition matrix element, we find $B(\\bar B^0\\to\\Lambda_c\\bar p)\\leq 1.1\\times 10^{-5}|g_{B^0p\\Sigma_b^+}/6|^2$ with $g_{B^0p\\Sigma_b^+}$ being a strong coupling for the decay $\\Sigma_b^+\\to \\bar B^0 p$ and hence the predicted branching ratio is well below the current experimental limit.
