  The supersymmetry (SUSY) may be one of the most favorable extensions of the
standard model (SM), however, so far at LHC no evidence of the SUSY particles
were observed. An obvious question is whether they have already emerged, but
escaped from our detection, or do not exist at all. We propose that the future
ILC may provide sufficient energy to produce SUSY particles if they are not too
heavy in the low background environment. The superflavor symmetry associates
baryons with mesons as long as both of them containing a heavy constituent and
a light one. In this work, we estimate the production rate of SUSY baryons near
their production threshold in terms of the $B\bar B$ production data. Our
analysis indicates that if the SUSY baryons with masses below $\sqrt s/2$
($\sqrt s$ is the ILC energy) exist, they could be observed at future ILC.
