Strange and charmed baryon pair productions in proton-antiproton collisions are studied in the effective Lagrangian and Regge approaches. Unknown parameters of both models are determined from the comparison with the existing data for strangeness productions. Then, we predict charm production cross sections by extrapolating the amplitudes for strangeness productions to those for charm. As a result, the total cross sections are about 
to 
times smaller than those of strangeness productions, depending on the final states. By using the known total cross sections for strangeness, 
for 
and, 
for 
, the total cross sections for charm productions are predicted to be 
for 
, 
for 
, and 
for 
. Our results can be tested in the future experiments at 
ANDA.
