We have measured the inclusive production cross sections of hyperons and charmed baryons from $e^+ e^-$ annihilation using a $ 800 fb^{-1} $ data sample taken near the $\Upsilon$(4S)resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider.
The feed-down contributions from heavy particles are subtracted using our data, and the direct production cross sections are compared for the first time.
