  We present the results of searches for the standard model Higgs boson at CDF
in final states with bottom quarks. Results are derived from the complete
Tevatron Run II dataset, with a measured integrated luminosity of 9.5 fb$^{-1}$
of proton-antiproton data. The searches are performed for assumed Higgs masses
between 90 and 150 GeV, for Higgs bosons produced in association with W or Z
bosons. Employing several improved techniques, these are currently the most
sensitive searches in the world for these processes, surpassing previous CDF
results by 30% beyond what would be expected from the addition of new data
alone. Combining the search sensitivity of these production modes, 95% upper
confidence limits on the standard model cross section times branching fraction
are derived, yielding an observed (expected) upper limit of 4.3 (1.8) times the
standard model prediction for a 125 GeV Higgs boson. The significance of the
data relative to the background-only hypothesis is 2.5 sigma.
