YFeO$_3$ and LaFeO$_3$ are members of the rare-earth orthoferrites familywith \textit{Pbnm} space group. Using inelastic neutron scattering, thelow-energy spin excitations have been measured around magnetic Brillouin zonecenter. Splitting of magnon branches and non-zero magnon gap is observed forboth compounds, which is similar to the behavior observed in multiferroicBiFeO$_3$. Spin wave calculations which include both Dzyaloshinsky-Moriyainteractions and single-ion anisotropy in the spin-Hamiltonian comprehensivelyaccounts for all the experimentally observed features. Our results offerinsight into the unifying physics underlying the Fe$^{3+}$-based perovskites aswell as their distinguishing characteristics.
