  Higgs-boson production in association with bottom quarks is an important
discovery channel for supersymmetric Higgs particles at the Tevatron and the
LHC. We present higher-order QCD predictions for inclusive cross sections and
for the production of a Higgs boson in association with high-p_T bottom quarks.
We compare calculations performed in a four-flavour scheme based on the parton
processes gg,qqbar -> b bbar H with five-flavour scheme calculations based on
bottom-quark scattering.
