We study bottom flavor abundance in the early Universe near to a temperature
$T_mathrm{H}simeq150,mathrm{MeV}$, the condition for hadronization of
deconfined quark-gluon plasma (QGP). We show bottom flavor abundance
nonequilibrium lasting microseconds. In our study we use that in both QGP, and
the hadronic gas phase (HG) $b$ and $bar b$ quarks near $T_mathrm{H}$ are
bound in B-mesons and antimesons subject to $CP$ violating weak decays. A
coincident non-equilibrium abundance of bottom flavor can lead to matter
genesis at required strength: a) The specific thermal yield per entropy is
$n_b^{th}/sigma=10^{-10}sim10^{-13}$. b) Considering time scales, millions of
cycles of B-meson decays, and $bbar b$-pair recreation processes occur.
