A model for baryonic Regge trajectories compatible with the threshold behavior required by unitarity and asymptotic behavior in agreement with analyticity constraints is given in explicit form. Widths and masses of the baryonic resonances on the N and {delta} trajectories are reproduced. The MacDowell symmetry is exploited and an application is given.
