We present tests of different spin and parity hypotheses for a particle H of mass 125 GeV produced in association with a vector boson and decaying into a pair of b-quarks. We use the combined analysis of the WH->lvbb, ZH->vvbb, and ZH->llbb channels using the full Run 2 dataset collected at a center-of-mass energy of sqrt(s)=1.96 TeV with the D0 detector at the Fermilab Tevatron collider. We also present a search for neutral supersymmetric Higgs bosons in the bh->bbb and bbh->bbbb final states. Resulting experimental limits and techniques used to enhance signal sensitivity and to model dominant backgrounds will be discussed.
